NAME
OpenOffice::OODoc::Text - The text processing submodule of OpenOffice::OODoc
DESCRIPTION
This manual chapter describes the text-oriented methods of OpenOffice::OODoc, implemented by the OpenOffice::OODoc::Text class, and inherited by the OpenOffice::OODoc::Document class.
These methods are not essentially dedicated to string processing; they are more precisely focused on text containers. A text container is a document element which can (and must) be used in order to support a text and integrate it at the right place and according to the right presentation rules. The OpenDocument specification defines a lot of such containers, and the present API supports many of them, such as paragraphs, headings, tables (or spreadsheets), lists, sections, and draw pages. Some of these containers can host other containers: for example, a table contains rows, a row contains cells, a section can contain almost everything including other sections, etc.
These features are text-oriented, but can be used on documents of any class, such as spreadsheets or presentations as well as text documents. So, the 'Text' word doesn't mean that the features described in the present manual chapter are dedicated to OpenDocument Text (ODT) documents only. In the other hand, a few methods can't apply to any document class (ex: creating or retrieving draw pages makes sense with presentation and drawing documents only).
OODoc::Text should not be explicitly used in an ordinary application, because all its features are available through the OpenOffice::OODoc::Document class, in combination with other features. Practically, the present manual is provided to describe the text-oriented features of OpenOffice::OODoc::Document (knowing that these features are technically supported by the OpenOffice::OODoc::Text component of the API).
The OpenOffice::OODoc::Text class is a specialist derivative of OpenOffice::OODoc::XPath for XML elements which describe the text content of OOo/ODF documents. Here, "text content" means containers that can host text containers (i.e. tables, lists...) as well as flat text.
Knowing that the "styles.xml" member of an OpenDocument file can contain text (because some style definitions, such as page headers or footers, can contain text), the presently described features can be used against this member as well as the "content.xml" member.
This module should be used in combination with OpenOffice::OODoc::Styles, via the OpenOffice::OODoc::Document class, if the application has to handle detailed presentation parameters of text elements. This is because such parameters are held in styles elements and not in the text elements themselves, according to the principle of separation of content and presentation which is one of the foundations of the OpenDocument format.
Methods
Constructor : OpenOffice::OODoc::Text->new(<parameters>)
Short Form: odfText(<parameters>)
This constructor should not be explicitly used in ordinary applications
knowing that all the features of the returned object are inherited by
any Document object.
See OpenOffice::OODoc::XPath->new for common arguments.
Returns an OODoc::XPath OpenDocument connector with additional
features mainly focused on text containers.
This constructor is generally not explicitly called, knowing that
it's automatically triggered each time a Document object is created.
The XML member loaded by default is 'content.xml'. The most common
creation method is like this:
my $doc = odfText(file => 'my_file.odt');
This constructor should generally not be called directly, because it's
inherited by odfDocument().
Other parameters can be supplied as options (see the properties list
at the end of the chapter).
Example:
my %delim =
(
'text:h' =>
{
begin => '\sect{',
end => '}'
},
'text:list-item' =>
{
begin => '\item'
}
'text:footnote-body' =>
{
begin => '\footnote{',
end => '}'
}
);
my $doc = odfText
(
file => 'filename.odt',
paragraph_style => 'My Paragraphs',
heading_style => 'My Headings',
delimiters => { %delim }
);
This technique gives the default styles to be used when creating new
text elements. It also gives the particular delimiters (in this case
LaTeX style markers) to be used at the beginning or end of some
elements (in this case headings, list elements, footers) where the
text is to be exported "as is". See the getText method of
OODoc::Text for information about exporting text.appendDrawPage([options])
In a presentation or drawing document, appends a new page at the en
of the document.
Possible options are:
name => page name (unique)
id => page numeric ID (unique)
style => page style name
master => master page name
Returns the new draw page element if successful, undef if not.appendHeading([options])
Creates a new heading of any level and appends it to the end of the
document.
Options are given as a hash [key => value]:
'text' => <heading text>
'level' => heading level, default is 1
'style' => heading style, default is 'Heading 1'
Examples:
$doc->appendHeading(text => 'Next section');
adds the text 'Next section' as a level 1 heading.
$doc->appendHeading
(
text => 'Chapter Conclusion',
level => '2',
style => 'Heading_20_2'
);
adds a level 2 heading to the end of the text body. 'Heading_20_n'
styles, where 'n' is the level number, are presently available by
default in OpenOffice.org.
You can give any XML attribute to the new heading except for style or
heading level. In this case, the program must construct a hash
containing pairs of key-values for the attributes you want to create
and pass it using the 'attribute' option. Example:
my %attr = ( 'att1' => 'value1', 'att2' => 'value2' );
$doc->appendHeading
(
text => 'Attributes are important',
level => '1',
style => 'Chapter heading',
attributes => {%attr}
);
If the 'text' option is empty, the heading is created with an empty
content.
Caution, creating headings with level attributes is not always
sufficient to produce the needed result. For example, in order to
generate headings with appropriate levels of numbering, each one
must be attached to the right position in a hierarchy of lists,
in combination with appendItemList(), insertItemList(), and
appendListItem().
Note: this method can only be used with a new header i.e. it adds
while it creates. To add an already available element using
getHeading() from the same document or from another document, use
the appendElement() method instead which is inherited from
OODoc::XPath.appendItem(list [, text => text ,style => style ,[other_options]])
See appendListItem().appendItemList([type => list_type, [style => style [, options]]])
Creates a new (empty) list and appends it to the end of the
document.
In OpenOffice.org 1 documents, an unordered list is the default,
and if the 'type' option is given with the value 'ordered', then an
ordered list is created. In Open Documents, the 'type' option is
ignored because there are generic lists only (a list is ordered or
"bulleted" according to a style, and not natively).
The 'style' options controls the list's style (as opposed to each
item's style). If absent, the list takes the default paragraph style
(see appendParagraph).
Like appendParagraph, this method actually creates a new list
element. To copy an existing list in the same document or in
another, use appendElement or replicateElement instead.appendListItem(list [, text => text ,style => style ,[other_options]])
Adds a new item to a list (ordered or unordered).
The first argument is the existing list element (created using
getOrderedList or getUnorderedList, for example). Options are the
same as for appendParagraph.
If the 'style' option is absent, the element is inserted according
to the following rule:
- if the new item is not the first one of the list, it takes the
same style as the first item;
- otherwise, it takes the default paragraph style of the document.
The new item is created as a paragraph container by default. A
'type' option may be provided in order to require another type.
Possible values are 'header', 'paragraph' or the XML name of any
OpenDocument-compliant text container.
If the type is provided and set to undef, the new item is created
as an empty element, so it could/should receive a content later.
An empty item could be used as the attachment point of another
list, in order to create a hierarchy of lists.appendParagraph(<options>)
Creates a new paragraph and appends it to the document.
Options:
'text' => <paragraph text>
'style' => <paragraph style>
An 'attribute' option is also available under the same conditions as
for the appendHeading method (see above).
If the 'text' option is empty, calling this method is the equivalent
of adding a line feed.
If the 'style' option is empty, the style from the 'paragraph_style'
property of the OODoc::Text instance is used.
By default, the new paragraph takes place at the end of the document.
But it's possible to attach it as the last child of an existing
text container (ex: a table cell). To do so, the container must be
provided through an 'attachment' option. For example, to append a new
paragraph in a table cell, one can write
my $cell = $doc->getTableCell("Table1", "B12");
$doc->appendParagraph
(
text => "The cell, reloaded",
attachment => $cell
);
Note: this method can only be used with a new paragraph i.e. it adds
while it creates. To add an already existing paragraph using
getParagraph from the same document or from another document, use
the appendElement, insertElement or replicateElement methods instead
which are inherited from OODoc::XPath.
Note: The repeated spaces are not properly processed, so any sequence
of spaces (whatever its length) in the 'text' string is replaced by a
single space in the target document. See setText() and extendText().appendRow(table [, options])
Appends a row to the end of the given table either by reference, by
logical name or by sequential number. By default, the new row is
simply an exact copy of the preceding row (in terms of content and
presentation). You can pass an options hash which will give certain
attributes to the created row, under the same conditions as for the
appendElement method of OODoc::XPath. The returned value is the
created row element.
Example:
open SRC, '<', 'data.txt';
my $table = $doc->getTable("Table1");
my ($h, $l) = $doc->getTableSize($table);
for (my $i = 0 ; my $record = <SRC> ; $i++)
{
last unless $record;
chomp $record;
my @data = split ';', $record;
my $row = $i < $h ?
$doc->getRow($table, $i) :
$doc->appendRow($table);
for (my $j = 0 ; $j < $l ; $j++)
{
$doc->cellValue($row, $j, $data[$j]);
}
}
The above program reads a CSV format data file sequentially (one
record per line, comma-separated fields). Each record is split and
put into a row in table Table1. On reading each new record, the
reference for the following row is loaded by getRow, until the total
number of rows is reached (total obtained previously using
getTableSize). If the table is already full, it is lengthened by a
row using appendRow. The internal loop loads the read data into the
row's cells (pre-existing or newly created). See the sections on
getTable, getRow, getTableSize and cellValue for a better
understanding of this example.
However, if good performance is what you are after, massive
repetition of this method is not recommended (e.g. for lengthening a
table dynamically, row by row, whilst loading external data into
it). Rather than running dozens or hundreds of successive
appendRows, it would be better for the application to read the total
number of records to be loaded (using, for example, select count if
from a relational database or otherwise preloading the data into an
ordinary Perl table) and create a table of appropriate size in
advance using insertTable() or appendTable().appendSection(name [, options])
Creates a new section with the given name, and appends it by default
to the end of the document body. If the "attachment" option is
provided, with an existing element as its value, the new section is
appended in the context of this element. For example, if the value
of "attachment" is an existing section, the new section is appended
as the last sub-section of the existing one.
A section may be used either to hold a local content or to insert
a subdocument which can be reached through an external link.
In order to insert a subdocument link instead of an ordinary section,
the application must provide a "link" option whose value is either a
local file path or an URL.
Example:
$doc->appendSection
(
"Article",
link => "http://mycompany.com/doc/article.odt"
);
Other possible options:
'style' allows the application to explicitly select a style
for the new section
'protected' write-protects the section when the document is
edited; "true" or "false", default "false"
'key' in combination with "protected" => "true", write-
protects the section by password (the value of
"key" is not the real password, but an encrypted
password, so the end-user will never remove the
protection by simply typing the key as it is
written in the program); see lockSection(),
unlockSection() and sectionProtectionKey()appendTable(name, rows, columns [, options])
Creates a new table with the given name, number of rows and number
of columns, and appends it by default to the end of the document
body. The name must be unique within the document (the call is
rejected if the name already exists). Returns the created table
element if successful.
Beware: Creating simple tables from scratch is very easy; however,
for a realistic application, it's strongly recommended to replicate
XML table templates previously created with an ODF-compatible editing
software. A reasonably sophisticated table implies dozens of style
definitions and would require a lot of perl code and a deep knowledge
of the ODF specification, while it could be created in a few minutes
through a WYSIWYG tool.
'rows' and/or 'columns', if omitted, are replaced by the 'max_rows'
and 'max_cols' properties of the document (see the properties below).
By default, the table is set to fit the entire width between the
left and right margins with equal sized columns, cells of type
string and without borders or background colour.
Possible options:
'table-style' => table style
'cell-type' => default cell type
'cell-style' => default cell style
'text-style' => default cell text style
The first option is the name of a table style which defines
certain global properties for the table (width, background colour,
etc.). See the OpenOffice::OODoc::Styles manual for information about
styles.
The second option is the cells' default data type. The main types
available are string, float, currency, date, percentage. Caution: to
be properly treated as having a numeric format in OOo/ODF, a
cell needs more than to be just marked 'numeric'. If the cell really
needs to be treated properly as a number, you must also give it a
cell style which itself refers to a number style. The cell-style
parameter can do this. However, even though the OODoc::Styles module
is there to otherwise help you create and add styles from a program,
this type of exercise can become very labour-intensive. We therefore
recommend using basic tables created in advance from document
templates or style libraries created from an office application,
rather than creating complex number tables from code.
The text-style option selects the paragraph style applicable to the
text displayed in each cell.
Once the table is created, you can obviously modify each cell's type
and style individually.
Example:
my $table = $doc->appendTable
(
"Rate", 22, 5,
'table-style' => 'Table1',
'text-style' => 'Text body'
);appendTableRow(table)
See appendRow.autoSheetNormalizationOff()
Deactivates the automatic sheet normalization.
See autoSheetNormalizationOn().autoSheetNormalizationOn('full')
autoSheetNormalizationOn(height, width)
Activates the automatic normalization of any used table.
This method instructs the API to automatically normalize anything
table or sheet as soon as it's reached through getTable() or another
table-related access method. The automatic normalization is not
activated by default. It can be deactivated at any time using
autoSheetNormalizationOff().
See normalizeSheet() for details about the arguments and the
effects.bibliographyEntryContent(id [, key1 => value1, key2 => value2, ...])
Gets, and optionally sets, the properties of a given (existing)
bibliographic entry. The optionally updated properties are provides
as a hash. The returned description is a hash.
The first argument can be either the logical identifier of the entry
(as it appears for the end-user) or a previously found bibliography
entry element (see getBibliographyElements()).
Example:
my %desc = $doc->bibliographyEntryContent
(
"GEN99",
author => 'Genicorp',
pages => 62
);
This sequence updates the "Author" and "Pages" values of the "GEN99"
entry, then returns all the content of the entry in %desc.
Caution: Several bibliography entries can have the same identifier.
This method processes one element at a time. In the example above,
only the first occurrence of the "GEN99" entries is updated. So, if
the user needs to ensure that all the entries with the same identifier
have the same content, the appropriate code should be something like:
my @entries = $doc->getBibliographyElements("^GEN99$");
foreach my $entry (@entries)
{
$doc->bibliographyEntryContent
(
$entry,
author => 'Genicorp',
pages => 62
)
}
Caution: This method allows the user to create any new property and
to put any value in any property, without control. For information
about the legal and/or recommended properties, see the OpenDocument
specification and the OpenOffice.org bibliographic project
(http://bibliographic.openoffice.org).bookmarkElement(element, name [, offset])
See setBookmark().cellCurrency(table, row, column [, currency])
cellCurrency(cell [, currency])
Get/set the currency unit of a cell.
If a currency is provided, the cell value type is automatically
switched to 'currency'.cellFormula(table, row, column [, formula])
cellFormula(cell [, formula])
Accessor which returns the formula (or function) contained in the
given table cell. Returns undef if no formula is found in the cell.
The cell address is the same as for getCellValue().
If a formula is given as the last argument, it is put into the cell,
overwriting any existing formula. No check of the syntax is carried
out on the inserted formula. It is up to the application to insert a
formula which conforms to OOo/ODF syntax. Example:
$doc->cellFormula(1,3,2, "sum <C2:C5>");
Note 1: inserting or replacing a formula does not directly modify
the value or text of the cell. Proper interpretation of a formula
does not happen until the fields are updated when the document is
reloaded into the office software.
Note 2: syntax and functionality of cell formulae differ greatly
between office applications.cellSpan(table, row, column [, hspan [, vspan]])
cellSpan(cell [, hspan [, vspan]])
In a spreadsheet document, get/set the span of a table cell,
knowing that this span can be one or more columns. The cell addressing
is the same as with getTableCell().
Example:
$doc->cellSpan($table, "B4", 3);
creates a 3-cell span from B4 in a spreadsheet.
With only one span argument, this method works for horizontal, left to
right expansion. With an additional argument, the expansion is bi-
directional, covering one or more rows below the given cell. The
horizontal span should be set to 1 in order to get a vertical span
only.
The text of the covered cells (if any) is concatenated to the original
content of the expanded cell (as in OOo Writer or Calc).
The user should make sure that the cell expansion will not invade the
span of another, previously expanded cell. Assuming A is a the target
of cellSpan(), B is an existing expanded cell, and C is a covered cell
in the span of B, the following rules apply:
If B is to be covered by the span of A, the span of B is automatically
reset to 1, so C becomes visible, then B is covered by A. But if C is
in the target range of cellSpan() while B is not, the method produces
an inconsistency in the table (this inconsistency doesn't prevent
OpenOffice.org and KSpread from loading the file but the span of A is
just ignored).
In list context, the method returns the horizontal span, then the
vertical span. In scalar context, it returns the horizontal span only.
Caution: when related to table cells, "span" has not the same
meaning as when related to flat text (see getSpan() and setSpan()).cellStyle(table, row, column [, stylename])
cellStyle(cell [, stylename])
Get or set the style of a table cell.cellValue(table, row, column [, value [, text]])
cellValue(cell [, value [, text]])
Without the "value" argument: see getCellValue().
With "value" (and, optionally, "text"): see updateCell().cellValueType(table, row, column [, type])
cellValueType(cell [, type])
Get/set the data type of a table cell.
Possible value types are 'string', 'float', 'percentage', 'currency',
'date', 'time', 'boolean'.
Note: If an application must convert a 'string' cell to a numeric
one and fill it with a numeric value, cellValueType() must be called
*before* cellValue(). Ex:
my $cell = $doc->getTableCell('Sheet1', 4, 8);
$doc->cellValueType($cell, 'float');
$doc->cellValue($cell, 12.34);checkIndexMark(name, type [, context])
Checks the existence and validity of an index mark (see setIndexMark()
for details about range index marks). The mandatory argument are the
index entry identifier and the index entry type (namely 'toc' or
'alphabetical index'. A context element may provided in order to
restrict the search context.
This method may return 1, 0 or undef.
'1' means that the index mark is present and consistent;
'0' means that the index mark is present in the context but not valid;
undef means that the index mark doesn't exist in the context.
If the result is 0, the are 2 possible reasons: the start point or the
end point of the index mark has been found, but not both, or both have
been found but there relative positions are wrong (the end is located
before the start). Whatever the explanation, this result means that some
cleaning should be done (see deleteIndexMark()).checkRangeBookmark(name [, context])
Checks the existence and validity of a range bookmark (see setBookmark()
for details about range bookmarks). The mandatory argument is the
bookmark name. A context element may provided in order to restrict the
search context.
This method may return 1, 0 or undef.
'1' means that the range bookmark is present and in the right order;
'0' means that the bookmark is present in the context but not valid;
undef means that the bookmark doesn't exist in the context.
If the result is 0, the are 2 possible reasons: the start point or the
end point of the range has been found, but not both, or both have been
found but there relative positions are wrong (the end is located before
the start). Whatever the explanation, this result means that some
cleaning should be done (see deleteBookmark()).columnStyle(column_element [, style])
columnStyle(table, column [, style])
Returns the style name of the given column or replaces it with a new
one. A column can be indicated either directly by reference or by
the pair [table, column number]. The table itself can be indicated
either by a table element, its number or its logical name. If the
'style' argument is given, it replaces the old column style.
Giving a column a style is actually the only way to control the
width of a column in a table.
Example:
$doc->columnStyle('Table1', 2, 'NewStyle');
Caution: columns are numbered beginning at 0.copyRowToHeader(table, rownum)
copyRowToHeader(row)
This method appends a copy of a given table row to the header of the
table. It may be called repeatedly, allowing multi-row header
creation.
A table header is a row, or a sequence of rows, that is displayed at
the top of a table and repeated at the top of every page if the table
is spanned across more than one page.
The given row remains in place unchanged; it's used as a template for
the new header row.createParagraph([text [, style]])
Creates a free paragraph for later use. Unlike appendParagraph() or
insertParagraph(), this method doesn't attach the new paragraph to
the document.
Without arguments, the paragraph is created empty. The first argument,
if any, provides the text content of the paragraph. The second one,
if any, is regarded as the style name; the default style is
"Standard". createTextBox(options)
Creates a new text box. Can apply to any document class, but mostly
used in presentations or drawings (where text boxes are required to
host text content).
Text boxes are implemented through frame element, so you should see
createFrame() in the OpenOffice::OODoc::XPath manual chapter in order
to understand the meaning of every option.
The following options are allowed (and generally required in order
to make a text box really visible and properly rendered):
page: the page where the box must be attached; in presentations or
drawings, this option should be set with the page name;
name: the (unique) name of the text box;
size: the size of the box;
position: the page-relative position;
style: the graphic style of the box; like an image box, a text box
often requires a style to be properly displayed;
content: the content to be displayed in the box; if this option is
set to a literal, the given content is inserted as a paragraph in
the box; if the given value is the reference of an element, this
element is attached as is in the box (so it's possible to insert
any complex object, such as a table, an item list, etc).
The method returns the reference of the new text box element.
The example below creates an graphic style ("TB"), then a text box
("The Box") which uses the new style. See O::O::Styles for comments
about createStyle(). The text box is attached in a presentation page
identified by its name ("AnyPageName"). The size (width then height)
and position (x, y) options are provided in centimeters (other units
are allowed), each one in a single string.
$doc->createStyle
(
"TB",
family => "graphic",
parent => "objectwithshadow",
properties =>
{
'style:vertical-pos' => 'from-top',
'style:horizontal-pos' => 'from-left',
'style:vertical-rel' => 'page',
'style:horizontal-rel' => 'page'
}
);
$doc->createTextBox
(
page => "AnyPageName",
name => "The Box",
size => '12cm, 4cm',
position => '8cm, 14cm',
style => 'TB',
content => "The text in the box"
);
In this example, the content option is set to a flat text, so
it will be inserted as a standard paragraph. If we want to insert
a paragraph with a non-default style, this option must be set to
the reference of an existing paragraph (which may have been created
using createParagraph() or copied from another place).defaultOutputTerminator([chars])
Get or set the default terminator character for text export.
Example:
$doc->defaultOutputTerminator("\n");
After this instruction, a line-break will be appended at the end of
every paragraph or header exported by getText(), selectTextContent()
or other text extracting methods.
To reverse this behaviour, the user can call this method with an
empty string.
Without argument, returns the currently selected terminator, if any.deleteBookmark(name [, context])
Deletes the bookmark owning the given name (if defined).
A context optional argument is provided; if so, the bookmark is deleted
only if it's located in the given context.
If several bookmarks wrongly own the same name, they are removed.
The method returns the number of physical deleted elements, i.e. 1 for
a regular position bookmark, 2 for a range bookmark, 0 for nothing. Any
other return value means that deleteBookmark() has cleaned up a strange
situation (ex: more than one bookmark for a single name, a position
bookmark with one start and many ends, and so on).
Warning: if the context argument is set (or if the default current
context is not the whole document), and if the bookmark to be deleted
is not entirely included in the context, the result may be a partially
deleted bookmark (wrong).
See also deleteBookmarks().deleteBookmarks([context])
Delete all the bookmarks in the current context (by default the whole
document) or in a given optional context, and returns the number of
physical deleted elements (that may be greater than the number of
deleted bookmarks, knowing that a bookmark may be stored a one or two
XML elements).
Warning: some inconsistencies may result if the context is not the whole
document, knowing that a range bookmark could run across the border of
the restricted context.
See also deleteBookmark().deleteColumn(table, col_num)
deleteColumn(col_elt)
Deletes a given column in a given table.
Caution: Before using this method, the application should ensure that
the whole area from the beginning of the table to the last cell of the
column to be deleted is "normalized". See normalizeSheet() for details
about table normalization.deleteHeading()
See removeHeading().deleteRow(table, row_num)
deleteRow(row_elt)
Deletes a given row in a table.deleteIndexMark(id [, type [, context]])
Deletes the index mark owning the given identifier (if defined).
The first argument (mandatory) is the index mark identifier. The second
argument is the index type ('alphabetical index' or 'toc', the first one
is the default).
A context optional argument is provided; if so, the index entry is
deleted only if it's located in the given context.
If several index marks wrongly own the same identifier, they are
removed.
The method returns the number of physical deleted elements, that should
be 0 (if the index mark did not exist) or 2 (the start and the end
points). Any other return value means that deleteIndexMark() has cleaned
up a strange situation (less or more than two range delimiters).
See also deleteIndexMarks().deleteIndexMarks([type [, context])
Without argument, deletes all the TOC marks and alphabetical index marks
in the document (or the default context).
The first argument, if set, non-blank and non-empty, restricts the
deletion to one type of index marks; it should be either 'toc' or
'alphabetical index' (unless the user need to remove non standard index
marks).
A particular context may set through the third argument in order to
restrict the index mark removal to the content of a particular element.
See also deleteIndexMark().drawPageId(page [, new_id])
Returns the internal identifier of a presentation page, and changes
it if a second argument is provided. The page id is a positive
integer.
The first argument must comply to the same rules as with getDrawPage.drawPageName(page [, newname])
Returns the visible name of a presentation or drawing page.
The first argument can be a page order number, a page element or the
present page name (see getDrawPage). The page is renamed if a
second argument is provided. Example:
$doc->drawPageName("oldname", "newname");deleteTableColumn(table, col_num)
See deleteColumn().deleteTableRow(table, row_num)
See deleteRow().expandSheet()
Synonym of expandTable().expandTable(table, height, width)
Increases the size of the given table or spreadsheet.
This method silently executes a full normalization of the table before
resizing it. See normalizeSheet() for details about this operation.
This method is specially useful in order to ensure the availability of
an appropriate workspace in a spreadsheet whose apparent size is
almost unlimited through the GUI of a typical desktop software but
but whose real size is unknown and/or doesn't include all the target
area of the application.
The vertical expansion is implemented by repetitive replication of the
last row, while the horizontal expansion is implemented by repetitive
replication of the last cell of the last row. So the new cells in the
right side are copies of the old bottom-right cell, while the new rows
are copies of the old last row.
Any size argument which is not larger than the previous height or width
is silently ignored, so method produces the same effect as
normalizeSheet() with the "full" parameter.
The return value is the table element itself in scalar context, or
the table size in array context.
Note that there is no direct method to shrink a table. However, it's
possible to do the job by deleting selected rows and or columns
through deleteTableColumn() and/or deleteTableRow().extendText(element, text [, style [, offset]])
Inserts the text provided as the second argument into the element
specified by the first argument. The second argument may be either a
flat string or another existing text element.
If the 'text' argument is a paragraph or heading element, the text
content (and not the element itself) is inserted. But if 'text' is
any other element (for example: a variable text field or a sequence
of spaces), its inserted as is.
This method is an improvement of the general extendText() method
which is documented in the OpenOffice::OODoc::XPath manual page.
If a third argument is provided and is neither 0 nor an empty string,
it's regarded as the desired style of the new text, which is inserted
as a "styled span" (see setSpan() for details about text "spans").
By default, the text is inserted without any special style (i.e. with
the same style as the containing element).
The new text is, by default, appended to the existing content of the
element. However, if a valid numeric value is provided as the fourth
argument, the new text is inserted within the existing content, at the
given offset. If the offset is negative, it's counted backwards from
the end of the string. If it's set to 0, the insertion takes place at
the beginning.
$doc->createStyle
(
"BlueYellow",
family => "text",
properties =>
{
"fo:color" => odfColor("blue"),
"fo:background-color" => odfColor("yellow")
}
);
my $p = $doc->getParagraph(4);
$doc->extendText($p, "New text", "BlueYellow", 5);
In the example above, "New text" is inserted at the offset 5 within
the 5th paragraph, in blue letters on a yellow background.
Of course, the offset argument can't be passed unless the style one is
present. However, in order to pass an offset without setting a style,
the application has just to provide a 0 or an empty string as the
third argument. Example:
$doc->extendText($p, "New text", "", 5);
Every string inserted through this method looks like it had always
been a part of the original string when edited using OOo. However,
each one remains stored in a separate space, like a "styled text
span" (see setSpan()). So, given the following example:
$doc->setText($para, "Old");
$doc->extendText($para, "New");
After this sequence, the displayable content of $para is "OldNew",
but "OldNew" is not retrievable by selectElementsByContent(),
setSpan(), or other text-searching methods, because "Old" and "New"
are physically stored in separate containers (each one can have a
distinct style). In addition, a subsequent call of extendText()
with an offset on the same target will not properly work if the
offset value is greater than the initial length (3 in the example).
However, all the internal text span borders may be removed by an
explicit call of flatten(). So, a third instruction could be
appended to the example:
$doc->flatten($para);
After this last instruction, the whole content of $para is stored
as a single string, and there is no internal separation between the
original content and the extension(s). In the other hand, flatten()
removes any previous formatting markup as well. For details about
flatten(), see OpenOffice::OODoc::XPath.getBibliographyElements([id])
Returns the list of the bibliographic entry elements contained in the
document.
If an argument is provided, the returned list is restricted to the
bibliographic entries matching it (this argument can be a regexp).
Example:
my @biblio = $doc->getBibliographyElements("^W3C");
returns the bibliographic entries where the identifier begins with
"W3C".getBookmark(name)
Returns the bookmark element (if defined) corresponding to the given
bookmark name.
If the bookmark covers a range of text (i.e. if it's not a position),
the returned element is the "bookmark start" one.getCell()
Synonym of getTableCell().getCellParagraph(table, row, column)
getCellParagraph(cell)
Returns the paragraph element contained in a given table cell, if
the cell contains a paragraph. If the cell contains more than one
paragraph, returns the first one.getCellParagraphs(table, row, column)
getCellParagraphs(cell)
Returns the list of the paragraph elements contained in a given
table cell (knowing that a single cell can contain one or more
paragraphs).getCellPosition(cell)
Returns an array corresponding to the zero-based, numeric coordinates
of a table cell in a document, which can be used later to retrieve
a cell at the same location through getCell(). The return values
represent, in this order, the table, the row and the column. The header
rows of the table, if any, are not counted.
Example:
my @coord = $doc->getCellPosition($cell);
A triplet such as (2, 4, 9) tells that the cell is located at the
10th position in the 5th row of the 3rd table of the document.
In scalar context, this method returns nothing more than the first
element of the triplet, i.e. the zero-based position of the table
in the order of the document. However, if the real need is to retrieve
the table element itself, $cell->parent->parent is more efficient.
This method produces a warning and returns undef if the argument is
not a table cell.
Caution: getCellPostion(), like any other accessor using object
coordinates related, works only with normalized tables.getCellValue(table, row, column)
getCellValue(cell)
Returns the value of a table cell, if the cell is defined and
uncovered. Caution, in order to get the cell element itself for
further processing, use getCell() instead.
The first form indicates a cell by its 3D coordinates, as with
getCell().
The second form (quicker) takes a cell element as its only argument
(e.g. as returned by a previous getCell call).
This method behaves in two different ways depending on the cell
type. The displayable text of the cell is regarded as the cell value
if the cell type is 'string'. If the cell type is one of the possible
numeric types ('float', 'currency', 'date'), the returned value is the
internal, numeric value.
This difference in handling is designed to allow programs to use
returned numeric values directly in calculations.
See also cellValueType().
Note: To get information about a cell other than its value or value
type (numeric, etc.), the best way is first to get its element
reference with getCell() and then use it with getAttribute.getChapterContent(heading [, options])
This method returns the list of the elements depending (from the
end-user's point of view) on a given heading element, not including
the heading element itself. The argument and the options are the
same as with getHeading().
Examples:
my @list = $doc->getChapterContent(2, level => 3);
foreach my $element (@list)
{
my $text = $doc->getText($element);
print "$text\n";
}
The code above selects and prints all the text elements below the
third level 3 heading of the document (not including the content of
the header itself. The following example creates a new section whose
content is made of a heading and the content of the depending chapter
(the heading text is used as the section name):
my $heading = $doc->getHeading(2, level => 3);
my $heading_text = $doc->getFlatText($heading);
my $section = $doc->appendSection($heading_text);
my @content = $doc->getChapterBodyElements($heading);
$doc->moveElementsToSection($section, $heading, @content);
(See appendSection(), getHeading(), moveElementsToSection() in the
present manual chapter, and getFlatText() in OpenOffice::OODoc::XPath)
Caution, this method returns a list of elements and not an element.
Chapters, unlike sections, are not defined in OpenDocument. So,
getChapterContent() should be used as a possible workaround in order
to isolate a logical set of content elements which is not packaged in
a section.getColumn(table, column)
Returns the element reference of the given column in the given
table. The first argument is either the table's sequential number in
the document, logical name or element reference. The second argument
is the column's number in the table. Synonym: getTableColumn.
Caution: The application should ensure that the area including the
needed column is "normalized". See normalizeSheet() for details about
table normalization.getDrawPage(pos/name)
For presentation and drawing documents.
Returns the element reference of the given page name or position.
If the argument contains an integer, the page is selected according to
its zero-based position. If the value is negative, the position is
counted backwards from the end.
If the argument is alphanumeric, it's regarded as a page name, and the
page is selected accordingly.
Caution: This method can't retrieve a page by name if the name
contains numeric characters only; selectDrawPageByName() should be
preferred to do so.getEndnoteCitationList()
Returns the list of all the endnote citations (i.e. references to
footnotes included in the text) contained in the document.getEndnoteList()
Returns the list of all the endnote body elements contained in the
document. Should be replaced by getNoteList() with the "class" option
set to "endnote".getFootnoteCitationList()
Returns the list of all the footnote citations (i.e. references to
footnotes included in the text) contained in the document.getFootnoteList()
Returns the list of all the footnote body elements contained in the
document. Should be replaced by getNoteList() with the "class" option
set to "footnote".getHeading(n [, options])
Returns the nth+1 heading element.
If n is negative, headings are counted backwards from the last.
getHeader(-1) returns the last heading element of the document.
The only one possible option is "level". It allows the application
to select the nth+1 heading element for a given level.
Example:
my $heading = $doc->getHeading(2, level => 3);
selects the third level 3 heading in the whole document.
See also getChapterContent().
Caution: without the "level" option, this method counts sequentially
through all headings along a single plane, irrespective of their
level. E.g. if you have a level 1 heading then two level 2 headings
then a level 1 heading, the call getHeading(3) returns the last
level 1 heading.getHeadingList([level => value])
Returns a list of heading elements (i.e. elements called 'text:h' in
the document body).
If the "level" option is provided, the list is restricted to the
headings having the given level.getHeaderRow(table [, row_number])
See getTableHeaderRow().getHeadingText(n)
Returns the text of the nth+1 heading element. Elements are counted
in the same way as for getHeading().getHeadingTextList()
Returns a list of document heading texts.
In a list context, the result is returned in the form of a list of
character strings. In a scalar context, the result is a single
string in which the headings are separated by a line-break character
("\n").
Note: This list is "flat". It contains no information about the
headings' hierarchy. To get a hierarchical contents list, you must
start with the list of headings obtained using getHeadingList and
check each element's level attribute ('text:level').getItemElementList(list)
Returns a list of elements which represent items of an ordered or
unordered list. The argument is a "list" element (obtained
previously e.g. using getItemList, getOrderedList or
getUnorderedList). Each element in this list can be used with item
handling methods.getItemList(n)
Returns the element which represents the nth+1 list in a document
if found.
WARNING: In the OpenOffice.org 1 documents, only "ordered lists" and
"unordered lists" can be present. In the Open Document format, there
are generic list objects only, and each one is made "ordered" or
"unordered" by its style. So, this method will never return anything
from an OOo 1 document.getLevel(element)
See getOutlineLevel().getList(n)
See getItemList().getListItem(list, n)
Returns the nth+1 item in a given list if found.
The list (1st argument) may be given either by its order number in
the document, or directly as an element reference.getNoteCitationList()
For OpenDocument only (doesn't work on old OpenOffice.org documents).
Returns the list of all the note citation elements (whatever their
note class, i.e. "endnote" or "footnote").getNoteClass(note_element)
Returns the class of the given note element. Possible values are
presently "endnote" and "footnote". Returns undef unless the given
element is a note.getNoteElement(class => $note_class, citation => $note_citation)
Returns the first note element matching the given class and citation,
if any. Returns undef if the target note element doesn't exist.
The "class" parameter is either "endnote" or "footnote".
The "citation" parameter is the numeric or literal which refers to
the note, as it's visible for the end user.
Caution: The uniqueness of a note citation in a given note class is
not a general rule. The citation is an identifier when it belongs to
an ordered sequence (such as 1, 2, 3... or "i", "ii", "iii"...). But
the author is allowed to use the same citation (ex: an asterisk) for
more than one footnote or endnote. In such a situation, the method
returns the first note matching the given citation and the given
class. As a consequence, the note identifier, if known, is a better
option (see the second form of getNoteElement()).getNoteElement(id => $note_identifier)
Returns the note element matching the given internal note identifier
(which is a "text:id" attribute according to the ODF specification).
This internal identifier is unique, whatever the note class, so the
"class" parameter is not needed. However, "class" may be provided as
an additional filter; if so, the method will return undef if the
element matching the identifier doesn't match the class.getNoteElementList()
Returns the list of the endnote and footnote main elements.getNoteList()
Returns the list of the endnote and footnote body elements.getOrderedList(n)
Returns the element which represents the nth+1 ordered list in a
document if found.
WARNING: Ordered lists are possible in the OpenOffice.org 1 format
only. Don't use it against OpenDocument.getOutlineLevel(element)
Returns the level number of a text element, or undef if the given
element don't have a level number. Every heading element should have
a level, while ordinary text body elements should not. Example:
my $level = $doc->getOutlineLevel($element);
if ($level)
{
print "There is a level $level heading\n";
}
else
{
print "Non-heading element\n";
}getParagraph(n)
Returns the nth+1 paragraph in the document body, or undef if the
given number is greater than or equal to the total number of
paragraphs in the document.
You can also pass a negative argument, in which case paragraphs are
counted backwards from the end (-1 being the last paragraph).
By paragraphs we mean 'text:p' elements, which excludes headers but
includes non-empty table cells, contents of list items and
footnotes.
Returned value is an element and not the text of the paragraph. All
read/write operations involving attributes and content can use this
element.getParagraphList()
Returns a list of paragraph elements (i.e. 'text:p' elements in the
document body).getParagraphText(n)
Returns the text of the nth+1 paragraph, counted using the same
rules as for getParagraph.getParagraphTextList([filter])
Returns a list of texts contained in the paragraphs of a document
('text:p' elements).
A filter can be passed as an optional argument (literal or regular
expression). In this case, only paragraph texts whose content match
the filter are returned.
In a list context, the result is returned in the form of a list of
character strings. In a scalar context, the result is a single
string in which the paragraphs are separated by a line-feed
character ("\n").getRow(table, row_num)
Returns the element reference which corresponds to a row in a table.
The first argument is either the table's sequential number in the
document, logical name or element reference. The second argument is
the row number in the table. Synonym: getTableRow.
This methods ignores the table header (if any). It can retrieve a
row in the table body only. See getTableHeaderRow().getRowCells(table, row)
getRowCells(row)
Returns the list of the uncovered cell elements corresponding to a
given table row. The row can be provided either by table ID and row
number or by direct row object.getSection(name/number)
If the first argument is a number, returns the nth+1 section in a
document (section numbers are zero-based; if the argument is negative,
the sections are counted from the end).
The second form allows you to select a section by its logical name (as
it would appear to the end user when editing the section's
properties). This name is obviously easier to use than a number.
Moreover, this type of selection means the application will still
work even if a section changes position within a document.
The returned object is a "handle" that can be used for subsequent
element creations or retrievals in the selected section.getSpanList([context])
Returns a list of elements, in the given context, which correspond
to texts which "stand out" from the regular flat text, i.e. which have
been given a style which makes them stand out from the rest of the
paragraph containing them. The context may be a paragraph, a section,
or any other text container. The context argument is optional; the
default context is the whole document.
For example, a word in italics or in font size 12 in a paragraph of
mostly standard characters in font size 10 is a 'span' element and
would therefore appear in a list returned by getSpanList.getSpanTextList([filter])
Gets a list of texts which "stand out" in the same way as
getSpanList and returns it under the same conditions as
getParagraphTextList or getHeadingTextList, with optional filter.getStyle(path, position)
getStyle(element)
Obsolete. See textStyle.getTable(number_or_name [, 'normalize'])
getTable(number_or_name [, length, width])
Returns the reference of a table, selected by name or number, in a
scalar context. In an array context, returns the table size, like
getTableSize().
This method works with spreadsheets as well as with tables included
in other documents.
If the first argument is a number, returns the nth+1 table in a
document (table numbers are zero-based; if the argument is negative,
the tables are counted from the end). If it's a string, the table is
selected by its its logical name (as it would appear to the end user
when editing the table's properties). This name is obviously easier
to use than a number. Moreover, this type of selection means the
application will still work even if a table changes position within
a document. But the retrieval by name works with two restrictions:
- if a table name is made of digits only, or if if represents a
numeric expression, it's automatically regarded as a table number and
the table is selected according to its sequential (zero-based)
position in the document; if (and only if) the given number is greater
than the position of the last table, the given argument is regarded as
a name (for example, if the document contains 3 tables, getTable(365)
will attempt to retrieve a table whose name is "365"); in order to
avoid any retrieval by number, use getTableByName();
- getTable() can't retrieve a table by name if the name contains
one or more "$", "{" or "}" characters; these characters are allowed
in the table names in text documents (ODT), but not allowed
in spreadsheets (ODS).
The returned object is a "handle" that can be used for subsequent
accesses to its components (rows, cells).
The additional arguments, if any, instruct OODoc to normalize they
target table in order to allow subsequent addressing of its content.
If the "normalize" keyword is provided, the table will be fully
normalized. If length and width arguments are provided instead,
only an accordingly limited area, beginning at the "A1" position.
Practically, getTable() uses normalizeSheet() in order to perform
this job, so you should have a look at the normalizeSheet()
documentation (in the same chapter) for explanations.
Examples:
my $sheet = $doc->getTable('Checklist');
returns the reference of the sheet (or table) corresponding to the
given name, without processing
my $first_sheet = $doc->getTable(0);
my $last_sheet = $doc->getTable(-1);
returns the references of the first and the last tables according to
the physical order of the document
($lines, $columns) = $doc->getTable('Friends', 'normalize');
fully normalizes the table whose title is "Friends" and returns itself
size.getTableByName(name [, 'normalize'])
getTableByName(name [, length, width])
Retrieves a table according to its name (if it exists). This methods
allows the retrieval of a table whose name is made of digits without
possible confusion between names and numeric positions.
The optional arguments and the limits are the same as for getTable().getTableCell(table, row, column)
getTableCell(table, coord)
getTableCell(row, column)
Returns the element which represents the given cell. Possible
arguments are respectively: the table number or its reference in the
document, row number and column number. Each table cell contained in
the body of an OOo/ODF document can be referenced in this
manner, as if it belonged to a single 3D table irrespective of the
rest of the document.
If the cell is defined in the spreadsheet but covered (because of a
cell merge), the return value is undef. In other words, this method
doesn't provide access to a covered cell.
The first argument can be either the sequential number of the table
(starting at 0), the logical name of the table, or a 'table' object
(which can be retrieved in advance using getTable). If it's a number
or a name, getTable() is automatically called by getTableCell() in
order to convert it in a 'table' object. However, if the first
argument is a row object (previously obtained via getRow() or
getHeaderRow()), the second one is processed as the column number.
Before using several cells in the same row, it's a good idea to get
the row object and then to use it in every cell selection, in order
to minimize the coordinates calculation.
In tables including one or more header rows, the best way to get a
header cell is to use a header row (previously obtained using
getHeaderRow()) as the first argument. If the first argument is a
table, getCell() looks in the table body only.
Alternatively, the user can provide the cell coordinates in a single
alphanumeric argument, beginning with one or two letters and ending
with one or more decimal digits, according to the same logic as in a
spreadsheet. So, for example
$doc->getTableCell($table, 'B12');
is equivalent to
$doc->getTableCell($table, 11, 1);
(Remember that, with the numeric coordinates, the row number is the
first argument, while with the alphanumeric, spreadsheet-like ones,
the column letter(s) come first.)
Numbers can also be negative, where position -1 is the last. For
example:
$cell = $doc->getCell(-1, -1, -1);
returns the very bottom right cell of the very last table in the
document $doc.
Returns a null value if the given cell does not exist or if it's
covered by the span of another cell.
Any cellXXX() method in this module uses the same cell addressing
logic as getTableCell().
CAUTION: Remember that OODoc works with the XML representation of
the tables, and not with the tables themselves. The [x,y] direct
addressing feature works as long as there is a continuous, one-to-one
mapping between the logical view and the physical XML storage of the
table. But, according to the OpenDocument specification, several
contiguous objects (cells or rows) are allowed to be mapped to a
single XML object when they have the same content and the same
style, in order to save some storage space. This optimization is
systematically used, for example, by OpenOffice.org Calc. In addition,
OODoc can't address a cell that could be displayed through the GUI
of a typical interactive spreadsheet software but that isn't stored
because it's not initialized yet. As a consequence, the direct
addressing logic of getTableCell() may require some preprocessing.
See normalizeSheet() and/or expandTable() about such preprocessing.
Remember that the table addressing is zero-based and
the row comes before the column in OpenOffice::OODoc, so, for
example:
$cell1 = $doc->getTableCell($table, 0, 0);
$cell2 = $doc->getTableCell($table, 31, 25);
returns respectively the A1 and Z32 cells.
Note: in a spreadsheet, (0,0) are the coordinates of the "A1" cell,
and, for example, (16, 25) are the coordinates of the "Z17" cell.getTableColumn(table, column)
See getColumn.getTableHeaderRow(table [, row_num])
Returns the element reference which corresponds to a row in a table
header, or undef if the given table has no header row.
The arguments are processes in the same way as with getRow(), but
the second argument is optional; it's required only if the table
has more than one header row (the 1st header row is returned by
default).
The returned elements can be used with subsequent cell access methods
in order to process header cells (see getTableCell()).getTableList()
Returns a list of table elements in a document.getTableRow(table, row)
See getRow.getTableRows(table)
Returns the list of the rows contained in the given table.
When the user needs to process every row in large tables, this method
allows some performance improvements, because it's less costly than
a lot of successive getRow() calls.getTableSize(table)
Returns the size of a table as a pair of values which represent the
number of rows and columns. The table can be specified either by
number, logical name or reference.
Example:
my ($rows, $columns) = $doc->getTableSize("Table1");getTableText(n)
Returns the content of a table, if found, whose number or reference
is given as an argument. If not found, returns undef.
The content of each cell is extracted according to the rules of
getCellValue.
In a list context, the returned value is a 2D table with each
element containing the corresponding cell in the document.
In a scalar context, the content is returned as a single string in
CSV format. In this case, the rows are separated by a delimiter set
by the instance variable 'line_separator' and the fields by the
variable 'field_separator' in the OODoc::Text object. (These
delimiters are by default "\n" and ";" respectively.)getText(path, position)
getText(element)
Exports the text contained in the given element according to the
means appropriate to that type of element.
If the 'use_delimiters' flag is set to 'on' (default), the content
of each element (others than ordinary paragraphs, table cell,
headers) is preceded and/or followed by a character string depending
on the type of the element. This also depends on the settings given
to the delimiter values 'begin' and 'end' by the 'delimiters' hash.
In a default configuration where the application has not provided
any specific delimiters, the following delimiters are used:
- '<<' before and '>>' after sections of text highlighted within
an element (e.g. words in bold or underlined within a paragraph
of 'standard' font characters).
footnote citations (in text body) are placed between square
brackets.
'{NOTE:' and '}' for the content of footnotes.
(Footnotes are physically inserted into the text at the place
where they are called, just after the link element indicating the
footnote's number. Its display at the foot of the page or elsewhere
is a trick of the graphical interface.)
An application can change these delimiters, add more for other types
of elements (e.g. paragraphs, headers, tables cells, etc.), or
deactivate them using outputDelimitersOff. This depends on where the
text is exported to e.g. display in editable "flat" format,
conversion to non-OpenDocument XML or a markup language other than
XML, generating code from text, etc..
A default export (ex: "\n") terminator can be set for any element that
is not listed in the 'delimiters' hash (see defaultOutputTerminator()
above).
If the element is an ordered or unordered list, the text produced is
a concatenation of all the lines in the list, each separated by a
line-break in addition to any delimiters. The default line break
character is "\n", but it can be set to any other string (including
an empty string) through the 'line_separator' property of the document
object.
If the element is a string table cell, getText behaves like
getCellValue. If the cell contains more than one paragraph, the text
produced is a concatenation of all the paragraph contents, each
separated in the same way as list items.
If the element is a table, getText behaves like getTableText.getTextBoxElement(name/number)
Retrieves a text box element by its unique name or by its order
number in the document (or in the current context).getTextContent()
Returns the text of a document, as "flat" editable text.
In a list context, the content is returned as a table with one text
element (header or paragraph) per element.
In a scalar context, the content is returned as a single character
string with each text unit (header or paragraph) separated by a
line-feed ("\n").
The returned text contains no style or level information, so there
is nothing to distinguish a header from a paragraph.
Same as selectTextContent('.*').getTextElementList()
Returns the list of all the text elements, including headers,
paragraphs and item lists.getTopParagraph(n)
Same as getParagraph but only considers top level paragraphs. The
contents of lists, tables and footnotes are excluded.getUnorderedList(n)
Returns the element which represents the nth+1 unordered list in a
document, if found.
WARNING: Ordered lists are possible in the OpenOffice.org 1 format
only. Don't use it against OpenDocument.hyperlinkURL(hyperlink [, url])
Get/set the URL of an hyperlink element. The first argument may be
a previously retrieved hyperlink element (see selectHyperlinkElement
below), or the URL of an existing hyperlink. If a second argument is
provided, it replaces the URL of the hyperlink element.
With only one argument, just returns the existing URL of the link,
or undef if the first argument doesn't match an existing hyperlink
element.inputTextConversion(text)
Returns the UTF8 conversion of the given text, supposed to be in
the local character set of the document (see the 'local_encoding'
property).insertColumn(table, col_num [, options])
Inserts a new column in an existing table at a given position.
The second argument must be the number of an existing column.
Caution: this argument must be a column number, and not a column
element.
The new column is created as a copy of the column a the given
position. It's inserted before or after the existing one, according
to an optional "position" parameter (default 'before').
Caution: before using insertColumn() against a spreadsheet, the
application should ensure that the whole rectangular area from the top
left cell ("A1") to the last used cell of the column at the target
position is "normalized" (see normalizeSheet() for details about the
table normalization).insertDrawPage(page/pos [, options])
In a presentation or drawing document, inserts a new page before
or after an existing page.
Possible options are the same as for appendDrawPage(), with an
additional one:
position => 'before' or 'after' (default 'before')
The new page is inserted before or after the reference page, according
to the 'position' option.
The first argument can be a draw page element reference (recommended)
previously returned, for example, by a previous page retrieval or
creation method call. Alternatively, it can be a page position or
visible name, so it's regarded in the same way as in getDrawPage().
Returns the new page element, or undef in case of failure.insertHeading(path, position, options)
insertHeading(element, options)
Same as appendHeading, but inserts the new heading before or after
another element.
Position is that of an existing element which can be another heading
or a paragraph. Can be given by [path, position] or by element
reference.
Possible options are the same as for appendHeading, with the
additional option 'position' which determines if the heading is
inserted before or after the element at the given position. Possible
values for this option are 'before' and 'after'. By default, the new
element is inserted before the given element.insertItemList(path, position [, options])
insertItemList(element [, options])
Same as appendItemList, but a new list is inserted at the given
position. The point of insertion can be given either by the pair
[path, position] or by element reference. Options are the same as
for insertParagraph.insertParagraph(path, position [, options])
insertParagraph(element [, options])
Same as appendParagraph, but a new paragraph is inserted at the
given position.
Position is that of an existing element which can be another
paragraph or a header. Can be given by [path, position] or by
element reference.
Options are the same as for appendParagraph, with the additional
option 'position' which determines whether the paragraph is inserted
before or after the element at the given position. Possible values
for this options are 'before' and 'after'. By default, the element
is inserted before the given element.insertRow(table, row [, options])
insertRow(row_element [, options])
Inserts a new row into a table. In its first form, pass the table
(reference, logical name or number) and the position number in the
table. In its second form, pass the element reference of the
existing row which is directly before or after the position where
you want to make the insertion.
By default, the new row is inserted at the position of the
referenced row, which displaces it and the rest of the table down by
one row position. However, you can insert it after by using the
'position => after' option. By default, the new row is an exact copy
of the referenced row, but you can assign particular attributes to
it in the same manner as the insertElement method of OODoc::XPath.insertSection(path, position, name [, options])
insertSection(element, name [, options])
Creates a new section and inserts it immediately before or after
an existing element (paragraph, header, table). The referenced element
can be indicated as in insertParagraph.
There is a "position" option which works in the same way as with
insertParagraph() or insertRow().
For other options, see appendSection(). For example, insertSection()
may be used in order to insert a subdocument in a master document.insertString(path, position, text, offset)
insertString(element, text, offset)
Inserts a flat character string in a given element (whatever the type
of element) at the given offset. If the offset is not defined, the
text is appended to the end of the element (however, if the offset is
provided and set to zero, the string is inserted at the beginning).insertTable(path, position, name, rows, columns [, options])
insertTable(element, name, rows, columns [, options])
Creates a new table and inserts it immediately before or after
another element (paragraph, header, table). The referenced element
can be indicated as in insertParagraph. The other arguments and
options are the same as for appendTable with the additional option
'position' as in insertParagraph.insertTableColumn(table, col_num [, options])
See insertColumn().insertTableRow(table, row [, options])
insertTableRow(row_element [, options])
See insertRow().lockSection(section [, key])
Installs a write protection on the given section.
If a second argument is provided, it's stored as an encrypted key
which is associated to the write protection. Caution, it's not the
key as it should be typed by the OOo end-user.
Such a write protection works only when the document is edited through
an OpenOffice.org-compatible desktop software. It doesn't prevent the
programs using OpenOffice::OODoc from deleting or updating the
protected sections.makeHeading([options])
Creates a new heading element, or marks as a heading an existing
element.
Options:
element => an arbitrary existing element
If this option is provided, the given element is converted in place
to a heading, whatever its original type and position. No element
is created.
Without the 'element' option, a new heading element is created and
returned for later use. This element is free; it's not automatically
attached somewhere in the document. For direct heading creation and
attachment, you should prefer appendHeading() or insertHeading().
level => a numeric, positive integer value
Sets the hierarchical level of the heading (remember 1 is the top
heading level). Caution: no default value.
style => the name of a convenient heading style
While it's not mandatory, the 'style' option and a properly defined
heading style are generally required in order to allow the office
software to really process and display the element as a heading with
the right hierarchical level. Of course, any previously existing
hierarchical style is reusable here.
The main purpose of this method is to allow quick heading hierarchy
creation in a "flat" document. For exemple, an application can select
a set of flat paragraphs matching a given condition and convert each
one in place to a heading with a given level.moveElementsToSection(section, list)
Moves a list of elements from any place to a section.
The section may be passed by name or by element reference; it must be
an existing one (no new section is created).
The list is a set of arbitrary elements (including sections). Each one
is cut from its previous place and appended to the section in the
order of the list, without document consistency check.normalizeSheet(sheet, rows, columns)
normalizeSheet(sheet, 'full')
This method preprocesses a given sheet so its components (rows,
cells) become available for all the table-oriented methods described
in this chapter. In some situations, this method must be used before
any attempt to address any individual table component (column, row or
cell). The return value is the target table object in a scalar context
and the size (height, width) in an array context.
This method works with any kind of ODF tables, whatever the containing
document, and not only with spreadsheets.
In the first form, the 2nd and 3rd arguments define the size of a
rectangular area, beginning at the first cell ([0, 0] or "A1"), to
be processed, in order to save time and CPU resources when the
application needs to address objects only in the first corner of a huge
table.
The second form allows the OODoc to normalize the whole table,
whatever the size. It's certainly the preferred form, as long as
the target sheets are reasonably sized or the hardware is powerful
enough.
The processed area becomes a workspace which is safely
addressable by any cell/row/column processing method. This
preprocessing is sometimes required, sometimes not. For example,
it's required on present OpenOffice.org Calc spreadsheets, and
useless on present OpenOffice.org Text tables.
It's automatically executed when getTable() is called with size
arguments (or with the "normalize" option); therefore it's not always
explicitly invoked by the applications. However, it's useful to know
its purpose.
The object addressing logic (which, for example, allows a program to
directly reach a cell using its coordinates) relies on a continuous,
regular mapping between the user's view and the physical XML storage
of the tables. However, the OpenDocument specification allows any
conforming application to map more than one table element to a
single XML element. When two or more contiguous objects contain
the same value and have the same style and the same data type, they
*may* be mapped to a single XML element with a repetition attribute.
As a consequence, the position of the appropriate XML element can't be
directly calculated from the logical coordinates of the object, and
OODoc needs to scan the table in order to get all the repetition
attributes and calculate the real mapping. In addition, updating an
object whose the XML corresponding element has a repetition attribute
would automatically update all the objects mapped to the same element,
producing unpredictable and generally wrong results.
OpenOffice.org Calc systematically uses this storage optimization in
spreadsheets, while OpenOffice.org Writer doesn't use it for tables in
text documents. In Calc (sxc/ods) documents, the XML mapping of the
whole content is "denormalized" in order to save memory: several table
components can be mapped to a single XML element, so the XML address
of each one can't be simply calculated from its logical coordinates.
In order to allow the spreadsheet components to be addressed with the
same methods as the Writer table components, normalizeSheet()
reorganizes the XML mapping of the given sheet.
Caution: The OpenDocument specification doesn't make any difference
about this point between tables included in text documents and tables
in spreadsheet-only documents. So any ODF-compliant application
*could* denormalize the XML storage of any table and use the
repetition attributes. As a consequence, normalizeSheet() *could* be
required in the future for other documents than OOo Calc ones.
This method is not (presently) always needed for tables included
in OpenOffice.org Writer (odt/sxw) documents, because their storage is
"normalized" (i.e. each component is mapped to an exclusive XML
element), with the exception of the column objects. So,
normalizeSheet() is required with these tables when the application
needs to use a column-focused method such as getColumn(),
insertColumn() or deleteColumn().
In the other hand, normalizeSheet() is not required to address a sheet
which has been created through the OODoc methods (provided that the
document has not been edited with another application software in the
meantime). These methods, i.e. appendTable() and insertTable(), create
normalized tables, whatever the document class.
Because this method is time and memory consuming, it should never
be used to reorganize the largest possible area of a sheet (meaning
thousands of rows and hundreds of columns that will probably never be
used). So it's action is limited to a given area, controlled by the
rows, columns arguments. When these arguments are not provided, the
method uses the 'max_rows' and 'max_cols' properties instead (see the
Properties section for other explanations). The processed area should
be sized in order to cover all the cells to be reached by the program,
and nothing more.
The first argument can be either the logical name of the sheet (as
it's shown in the bottom tab by OOo Calc), the sheet number, or a
table object reference, previously returned by getTable(). The return
value is the table object (or undef in case of failure).
Example:
$doc = odfDocument(file => 'report.ods');
my $sheet = $doc->normalizeSheet('Sheet1', 7, 9);
my $result = $doc->cellValue($sheet, 5, 6);
In the sequence above, a top left area of 7 rows by 8 columns is
pre-processed, so the cells from A1 to H6 of this sheet can be
reached according to the same addressing scheme as in Writer tables.
The last instruction gets the content of G6. Note that the second line
of this example could be replaced by
my sheet = $doc->getTable('Sheet1', 7, 9);
knowing that, when called with size arguments, getTable() automatically
executes normalizeSheet().
The following code normalizes the whole table, whatever its size (but
I don't recommend this option for tables containing thousands of rows
by hundred of columns):
$doc->normalizeSheet('Sheet1', 'full');
This last instruction could be automatically and silently executed
through the following one:
$doc->getTable('Sheet1', 'normalize');
The transformed sheets, of course, are readable by OOo Calc.
They simply take some more disk space when the processed spreadsheet
is saved. If the document is later read then written by OOo Calc,
the storage is optimized again, so the effects of normalizeSheet()
disappear.
normalizeSheet() is neutral against already normalized tables.
An explicit call to this method can be replaced by getTable() with the
additional length and width parameters. In addition, normalizeSheet()
is automatically executed before resizing each time a table is
processed by expandTable().normalizeTable(table [, rows [, columns]])
See normalizeSheet().outputDelimitersOn()
outputDelimitersOff()
Turns delimiters on or off. Used to mark up text exported by certain
methods like getText or selectTextContent.
The delimiters actually used depends on the table loaded into the
OODoc::Text instance via the 'delimiters' property.outputTextConversion(text)
Returns the conversion in local character set of the given text,
supposed to be in UTF8. The local character set of the document
is used (see the 'local_encoding' property).removeBookmark(id)
See deleteBookmark().removeHeading(position [, level => level_no])
removeHeading(element)
Removes the given heading element.
Example:
$doc->removeHeading(4);
removes the 5th heading (whatever its level) counted from the
beginning of the document.
See getHeading() for the argument and option.
If the argument is an element reference (second form), the type is
not checked and this method becomes the equivalent of removeElement()
(which is documented with OpenOffice::OODoc::XPath generic methods).removeHyperlink(path, position)
removeHyperlink(element)
Removes any hyperlink contained in the given element, leaving
in place the previously hyperlinked text.removeParagraph(position)
removeParagraph(element)
Removes the paragraph at the given position (first form).
The paragraph to be removed can be indicated by element reference
(second form). In this case, the type of element is not checked and
this method becomes the equivalent of removeElement.removeCellSpan($cell)
Removes the multi-column, multi-row span of a table cell. The width
and height of the cell are reduced to one column and one row.The
uncovered cells take the same style and data type as the reduced cell.
Caution: This method works with cells that heve been expanded using
the "number-rows-spanned" and "number-columns-spanned" OpenDocument
attributes. The cell expansion is done this way by the cellSpan()
method, as well as with the present version of OpenOffice.org Calc.
But other applications (including the present version of
OpenOffice.org Writer) can implement the cell merge using subtables
instead of span attributes.removeSpan(path, position)
removeSpan(element)
"Flattens" a text element, removing all presentation distinctions
which may mark out some substrings of its content.
For a more drastic result, see flatten() in OpenOffice::OODoc::XPath.
See also setSpan().renameSection(section, newname)
Renames an existing section using the second argument.renameTable(table, newname)
Renames an existing table using the second argument.rowStyle(row_element [, style])
rowStyle(table, row [, style])
Reads or modifies a table row's style, in the same way as
columnStyle does for columns.sectionProtectionKey(section)
Returns the encrypted key which is associated to the given section,
if the section is write-protected by key.
This method can't provide the real key (as it should be typed by
the end-user to unlock the section), but the returned value may be
reused in order to protect more than one section with the same
password.
See also unlockSection().sectionStyle(section, [newstylename])
Without argument, returns the current style of a given section.
If an argument is provided, it becomes the new style of the section.selectDrawPageByName(name)
In a presentation or drawing document, returns the page element
identified by the given name, or undef if the name is unknown.
The names to be used correspond to the displayed page names in
OpenOffice.org Impress.selectElementByBookmark(name)
Returns the element containing the given bookmark.
Caution: this method works with position bookmarks only, not with
range bookmarks (a range bookmark can be spread over several text
elements).selectElementByContent([context,] filter [...])
Returns the first text element whose content matches the 'filter'
(which can be an exact string or a regular expression), or undef
if no matching content is found.
With additional arguments after the filter, this method can be used for
replacement operations, or user-defined function triggering, in the same
conditions as selectElementsByContent().
The retrieval functionality of selectElementByContent() is the same
as selectElementsByContent(). See selectElementsByContent() for
limits.selectElementsByContent([context,] filter)
selectElementsByContent([context,] filter, replacement)
selectElementsByContent([context,] filter, action [, other_arguments])
This method returns the text elements whose content matches the search
criteria contained in 'filter' (a string that may be a regexp).
Note that this method can be used with a "non-filtering" regular
expression (".*") for unconditional movement through all text elements.
The default scope is the current context (practically it's the whole
document unless it has been changed using the currentContext() method).
However a context element may provided before the filter argument in
order to restrict the search space.
Be careful: if the search is successful, the returned elements may be
of various kinds; they are not always paragraphs or headings. They
may be, for example lower level text elements contained in paragraphs,
such as text spans or text hyperlinks.
The first form simply returns the given list without modifying the
text.
The second form returns the same list, but replaces all strings
which match the search criteria with the 'replacement' string as it
goes.
The third form, where the 'action' argument is a program function
reference, launches the given function each time the filter string
is matched. If defined, the value returned by the function is used
as the replacement value. If the function returns a null value
(undef) then no replacement is made. If it returns an empty string,
the retrieved text is deleted. The called function receives the rest
of the arguments, in this order:
1) all remaining arguments after 'action' ('other_arguments'), if any.
2) the element containing the retrieved text.
3) the string actually selected. If the filter is an exact string,
it is equal to the filter. If the filter is a regular expression,
it matches the "real" text retrieved.
The returned text (if any) must be encoded in UTF8.
The returned list is the same one returned by the first two forms.
Example:
sub action
{
my ($d, $element, $value) = @_;
if ($value < 100)
{
$d->removeElement($element);
return undef;
}
else
{
return $value * 2;
}
}
@list =
$doc->selectElementsByContent("[0-9]+", \&action, $doc);
In the above code, the subroutine "action" is called each time an
integer (one or more digits) is found. The subroutine receives the
document reference itself as its first argument (an OODoc::Text
object given by the application). Next, it automatically receives
the reference of the element in which the search string was found
(i.e. an integer) and, finally, it receives the exact number found
as its second-last and last arguments respectively. If this number
is less than 100, the element is removed. This is why the subroutine
needed the $doc object, used to invoke the removeElement method. If
more than 100, the number is multiplied by two and the result
replaces the original value in the element. The list returned by
selectElementsByContent contains all elements which contain the
search string, including any which might have been removed by the
called function while it was running.
It is the "main" elements containing strings which matched the
filter which are returned and not any of their sub-elements. For
example, if the returned string is found in one of the items in an
unordered list, the list element is selected and not the item.
Similarly, the table is selected when one of its cells matches the
filter, and the paragraph which is selected when the search string
is found in an attached footnote.
Important limit: This method can't retrieve elements whose display
content apparently matches the given filter but whose internal
storage doesn't. For example, a paragraph containing "foo bar" will
never be selected through selectElementByContent() if "foo" and "bar"
have different text styles. In the same way, a substring containing
multiple successive whitespaces will never match, because, according
to the ODF standard, multiple spaces (like tabs or line breaks) are
stored as special XML element instead of flat text. A character string
cannot be considered to match the filter unless it is entirely within
the same sub-element and all its characters have the same style. More
generally, a substring can match the filter if and only if it's
represented with only one style and if it doesn't contain multiple
spaces, tab stops or line breaks.selectHyperlinkElement(url_filter)
Retrieves the first hyperlink element (if any) whose the URL matches
the argument. Example:
my $e = $doc->selectHyperlinkElement("cpan");
could return an hyperlink element containing "www.cpan.org" as
well as "search.cpan.org", etc. The URL filter is processed as
a regexp.
Note: In order to get the text container (ex: paragraph) where the
hyperlink is located, the application can use the parent() element
method. Example:
my $e = $doc->selectHyperlinkElement("www.cpan.org");
my $p = $e->parent if $e;selectHyperlinkElements(url_filter)
Returns the list of the hyperlink elements whose the URL matches
the argument (and not only the first one).selectParagraphByStyle(stylename)
Returns the first paragraph (if any) using the given style.selectParagraphsByStyle(stylename)
Returns the list of the paragraphs using the given style.selectTextContent(filter)
selectTextContent(filter, replacement)
selectTextContent(filter, action [, other_arguments])
Returns a list of header texts and/or paragraphs (in the document's
own order) which match the given search criteria.
The filter can be an exact string or a regular expression. A filter
set to ".*" (no selection) will result in an export of the entire
text.
In all three forms, this method behaves like
selectElementsByContent, except that it returns text instead of a
list of elements.
Depending on the context (list or scalar), the result is returned in
the form of a list of rows or in the form of a single character
string where the elements are separated by a line-feed ("\n").
Note: called with a "non-filtering" regular expression, this method
will result in a "flat" export of the document:
print $doc->selectTextContent('.*');setAnnotation(element [, options])
Creates and inserts an annotation in a given element.
The possible options are:
'date' => the date/time of the annotation (ISO-8601 format); the default
is the current system date/time
'author' => the name of the author of the annotation; unless this
option is provided; the default is the current system user name
'text' => the text content of the annotation (no default)
'style' => a paragraph style for the annotation (no default)
'offset' => an integer value that specifies the position of the
insertion point of the annotation (default=0); a negative value means
that the position is counted backward from the end
'before' => a regular expression; specifies that the insertion point
should be before the first match
'after' => same as 'before' but the insertion point should be after the
first match
'replace' => same as 'before', but the matching substring is deleted
and replaced by the annotation
If 'before', 'after' or 'replace' (which are mutually exclusive) is set,
the 'offset' option, if provided too, specifies a search space
restriction and a search way. If 'offset' is positive, the search space
runs from 'offset' to the end; if 'offset' is negative, the search space
runs from the end and its size is the absolute value of 'offset'.
If 'offset' is 0, then it's possible to force the search backward from
the end to the beginning using an additional 'way' parameter whose
possible values are 'backward' and 'forward' (if 'way' is 'backward',
then 'offset' is regarded as negative whatever its sign).
Note that the 'capture' option doesn't work with annotations.
Returns the reference of the annotation element. Note that this
reference could be used later as a context for additional insertions
(for example in order to append several paragraphs to the content of
the annotation).setBibliographyMark(element, [, position_options][attributes])
Creates a new bibliography mark within a given text element.
The content of the new bibliography entry may be initialized through
a 'attributes' parameter whose value is a hash.
All the possible attributes of an ODF-compliant bibliography entry,
such as author, editor, isbn, title, year, and many others, are
allowed. A 'identifier' parameter is mandatory in order to get a
visible mark; note that this identifier is bibliography-specific and
is not the same as the generic identifier that could be get or set
using getIdentifier() and setIdentifier(). Other attributes are optional
(but, of course, an entry with nothing more than an identifier would not
be very useful in a final document).
By default, the object is inserted at the beginning of the target text
element. But, thanks to the optional position parameters, it can be put
anywhere within the text of the bookmarked element. The position
parameters are 'offset', 'before', 'after', 'replace', and 'way' and
they work like with setAnnotation().
$para = $doc->selectElementByContent("ODF-related book");
$doc->setBibliographyMark (
$para,
offset => -20,
replace => "reference needed",
attributes => {
identifier => "JDE",
title => "OASIS OpenDocument Essentials",
author => "J. David Eisenberg",
year => 2005,
isbn => "1-4116-6832-4"
}
);
This sequence replaces a "reference needed" substring in a given
paragraph by a bibliography mark that will be displayed by default as
"[JDE" and that contains various attributes. The 'replace' option means
that the given substring will be deleted and replaced by the mark. The
given (negative) offset means that the substring must be searched
backward and that the last 20 characters of the paragraph must be
excluded from the search space.setBookmark(element, name [, position_options])
According to the structure of the optional parameters, this method may
be used either to set a position bookmark (i.e. a named place holder
at some point of the text content in a pararaph) or to set a range
bookmark (i.e. a range of text that may spread across paragraph
boundaries and that is delimited by a bookmark start and a bookmark end
elements).
The first form is illustrated by the following example:
$doc->setBookmark(
$paragraph, "BM001",
offset => -20
before => "xyz"
);
This sequence puts a bookmark identified by "BM001" in a given
paragraph, immediately before the first "xyz" substring found in a
backward search among the last 20 characters.
The mandatory arguments are the target text element and the name of the
new bookmark (that should be unique).
By default, the object is inserted at the beginning of the text. But,
thanks to the optional position parameters, it can be put anywhere
within the text of the bookmarked element. The position parameters
are 'offset', 'before', 'after', 'replace', and 'way', and they work
like with setAnnotation(). See also setChildElement() in OODoc::XPath.
However, the 'text' option is ignored, knowing that a bookmark has no
text content. If the 'replace' option is used, the matching substring
is deleted and replaced by the bookmark, but the deleted text is not
reused.
The second form requires a bookmark name as the 1st argument, then
a 'start' and a 'end' parameters are required; each one is a hash of
parameters that specifies the position of one mark according to the same
options as for a position bookmark (namely with 'offset', 'before',
'after', 'replace', and 'way'). In addition, each of the 'start' and
'end hashes may contain an additional 'context' parameter that specifies
the elements that will contain the start and end marks, respectively.
The following example creates a range bookmark that starts after the
15th character of $p1 and ends before the "xyz" substring in $p2,
assuming that $p1 and $p2 are previously selected paragraphs in the
right order:
$doc->setBookmark(
"BM002",
start => {
context => $p1,
offset => 15
},
end => {
context => $p2,
before => "xyz"
}
);
The user is not prevented by default from creating a range bookmark
whose start point is after the end point of a range bookmark. However,
it's possible to force an order check using a boolean 'check' option.
If 'check' is 'true' while the order is wrong, the bookmark is not
created.
Note that the second form of setBookmark() is the same as
setRangeBookmark().setHyperlink(path, position, [context,] expression, url)
setHyperlink(element, expression, url [, options])
Puts an hyperlink on a text area in a given text element.
The first substring matching the given "expression" argument in the
text element (if any) will become the hyperlinked text. The "url"
argument is, of course, the URL of the hyperlink. If successful, the
method returns the new hyperlink element, or undef otherwise.
This short example illustrates the simplest use:
$doc->setHyperlink($para, "CPAN", "http://www.cpan.org");
This method works in the same way as setTextSpan(), described below,
but the text span is hyperlinked, and not only presented according to
a particular style. So, the third argument must be an URL instead
of a style.
A set of hyperlink attributes may be optionally provided as a hash
through an optional 'attributes' parameter. For example, the application
can provide a 'style-name' and a 'visited-style-name' as shown below:
$doc->setHyperlink (
$para, "CPAN", "http://www.cpan.org",
attributes => {
'style-name' => "ToBeVisited",
'visited-style-name' => "Visited"
}
);
'style-name' selects the style which applies to the text of the
hyperlink, as long as the URL is not visited, while
'visited-style-name' indicates, of course, the style in use if the
link location was already visited. These styles must belong to the
'text' family.
Other allowed hyperlink attributes are listed in the §5.1.4 of the
OASIS OpenDocument specification. They may be set through the
'attributes' options or later through the common setAttributes() method
(that may apply to the object returned by setHyperlink).
Note: The hyperlink is not always a remote URL, such as in the
example above. Internal references ere allowed as well. An
internal reference is prefixed by "#". If an internal reference
is a heading, it's prefixed by "#" and suffixed by "|outline".
An hyperlink may be aimed at a location inside another document;
such a link is the concatenation of a file path, a "#", and a local
name that makes sense in the target document (bookmark, heading...).setIndexMark(element, id [, options][, start =>{}, end =>{}])
Creates an alphabetical index entry in a given element. The first
arguments are the target element (generally a paragraph) and a
mandatory identifier (that should be unique).
A 'type' parameter allows to select the type of index; possible
values are 'alphabetical-index' or 'toc' (the last one stands for
"table of contents index mark"). The default is 'alphabetical-index'
(it may be wrote 'alphabetical index', knowing that every space is
automatically interpreted as a '-').
A 'content' parameter allows to specify an expression; the first
substring in the element that matches this expression will become the
indexed substring. It's possible to restrict the search area using a
'offset' option, a positive or negative integer; a positive value means
that the search space runs from the beginning to the given offset; a
negative value means that it runs backward from the end to the given
offset. In addition, a 'way' option whose legal values are 'forward' or
'backward' may control the search way: if 'way' is 'backward' then the
search is done backward even if 'offset' is not provided, and 'offset'
is regarded as negative even if it's provided without the minus sign.
Unless 'offset' is defined and negative, the default way is 'forward'.
The code below puts an index entry, identified by "idx001" and related
to the first match of a "xyz" expression:
setIndexMark(
$paragraph, "idx001",
type => 'alphabetical index',
content => "xyz"
);
Note that the 'type' option is provided for clarity only, knowing that
'alphabetical-index' is the default.
The following variant puts a TOC mark, searched backward from the end
of a given paragraph, within a 20-character-long area:
setIndexMark(
$paragraph, "idx001",
type => 'toc',
content => "xyz",
offset => 20,
way => 'backward'
);
The same result in this second example could be obtained without the
'way' option, with -20 instead of 20 as the 'offset' value.
A more sophisticated set or parameters may be provided in order to
specify the beginning and the end of the index mark separately. To do
so, 'content' must be omitted and replaced by the 'start' and 'end'
parameters, each one being a hash, just like with the second form of
setBookmark() that created a range bookmark, with a restriction:
The 'start' and 'end' optional parameters allows to specify the start
and the end positions of the index mark. Each one is a hash that may
contain the same options as with setBookmark() described below, namely
'offset', 'before', 'after', 'replace', and 'way', with the exception
of 'context', because (unlike a bookmark) an index mark is entirely
included in a single paragraph; its start and its end belong to the same
context, that is specified by the first argument.
The following example creates an alphabetical index mark that is
associated to a text range running from the "xyz" substring to the end
of the given paragraph:
$doc->setIndexMark(
$paragraph, "idx002",
type => 'alphabetical index',
start => {
before => "xyz"
},
end => {
offset => 'end'
}
);setNote(path, position, text [, options])
setNote(element [, options])
Creates and inserts a footnote or an endnote in the given element with
the given text as the note content. Returns the new note element in
case of success, or undef if the target element doesn't exist.
Supported options are:
'text' => the text content of the note
'class' => specifies the display class of the now note; may be 'footnote'
or 'endnote', default is 'footnote';
'id' => a note identifier, must be provided by the application and must
be unique for the class (be careful, the uniqueness is not automatically
checked and no default is provided);
'citation' => specifies the character string to display as note citation
(at the place in the host element where the note is anchored);
'label' => this option, if provided, means that the note should not be
processed as automatically numbered by the printing/editing applications
and that it should be represented by the given (arbitrary) string; if
'label' is defined, it becomes the default value of 'citation';
'style' => specifies the style of the note content (should be a regular
paragraph style).
By default, the object is inserted at the beginning of the text. But,
thanks to the optional position parameters, it can be put anywhere
within the text of the bookmarked element. The position parameters
are 'offset', 'before', 'after', 'replace', and 'way' and they work
like with setAnnotation().setRangeBookmark(name, start => {options}, end => {options}, ...)
Like the second form of setBookmark(): creates a range bookmark
according to a mandatory name (1st argument) and position options
provided through 'start' and 'end' parameters, each one being a hash
of options. See setBookmark() above for details.setSpan()
Deprecated.
See also setTextSpan() and setTextSpans(), more powerful but using
different options.setStyle(path, position, style_name)
setStyle(element, style_name)
Obsolete. See textStyle.setText(element, text ,[text, ...])
Alters the setText method of OODoc::XPath, so that it can handle
complex text elements. Please read the setText() entry in
OpenOffice::OODoc::XPath before the present entry.
If the element is a paragraph, a header or a list item (ordered or
unordered), its content is replaced by the 'text' argument. Caution:
setText() deletes and replaces the previous content of the paragraph.
If the element is a table cell, this method is the same as
updateCell.
If the element is a list (ordered or unordered), the content of each
'text' argument (however many) forces the creation of a new item
which is appended to the list (existing items remain unchanged).
Example:
$doc->setText($element, "Peter", "Paul", "John")
adds three items to the list if $element is a list. If $element is,
for example, a paragraph, then the second argument ("Peter") becomes
the content of the paragraph and the other arguments are ignored.
If the element is a note element or a note body, the given text
becomes the content of the note body.
If the element is a section, the whole content of the section is
deleted and replaced by a single paragraph containing the given text.
For all other types of $element, setText() behaves normally as defined
in OODoc::XPath.
Note: setText(), as any other text input method, doesn't properly
process repeated spaces by default. So, a sequence of spaces, whatever
its length, is replaced by a single space. See setText() and
extendText() in OpenOffice::OODoc::XPath.
setTextBoxContent(text_box, content)
Fills the given text box according to the given content.
The first argument may be the unique name, the order number or the
reference of a text box. The content is processed in the same way
as the content option in createTextBox().setTextField(element, field-type [, options])
Puts a variable text field in a given text element.
The 2nd argument specifies the type of field. The offical types are
described in §6.2 and §6.4 in the OpenDocument 1.1 specification,
corresponding to the so-called "document fields" and "metadata fields".
Examples of possible field type arguments are 'page number', 'chapter',
'paragraph count', 'time', 'file name', 'creator', 'creation date', etc.
The full syntax of the ODF field tags is not mandatory; the right
namespace prefix is automatically added if the given type indicator
doesn't contain a semicolon, and every space is replaced by a '-'. So,
a field type like, say "text:word-count" may be specified as
"word count".
This method may be used in order to display a declared user field. To
do so, the field type must be 'variable' instead of a regular ODF
text field, and a 'name' parameter must be provided with the name of an
existing (ot to be created) user field declaration.
While the content of a text field is often computed and displayed
dynamically by ODF-compliant viewers, it's possible to provide an
alternative text that will be persistently stored in the field and
available for applications which are note able to compute the content
and/or for users who need to know the last displayed value. Such an
alternative content is provided through a 'text' option.
It's possible to provide the new text field with one or more attributes
as a hash through a 'attributes' parameter. The most common attributes
are 'fixed' and 'style'; the first one is a boolean, the
second one is the name of a display format. The 'fixed' attribute, if
'true', prevents the ODF-compliant editors and viewers from refreshing
the content of the field (for example a fixed date field displays the
same date forever instead of the current date). The 'style' attribute
is the name of a display format (it's recommended to associate every
date, time or numeric field to a display format, while the default
display format of some ODF editors may be convenient for some needs).
Here the 'style' attribute is a shorcut for 'style:data-style-name';
see the ODF 1.1 specification §6.7.7 for a full description of this
kind of styles.
Other attributes depend on the kind of content. The following example
creates a fixed time field; the time value is stored as standard
(ISO 8601) date format and the alternative text is an arbitrary local
representation of the same; the presentation style (for applications
that can deal with ODF number styles) is "MyTimeStyle" (that is supposed
to be the name of a time style defined as an automatic style in the
document):
$doc->setTextField (
$paragraph, 'time',
text => "17:03:25",
attributes => {
fixed => 'true',
'time value' => "2010-02-25T17:03:25",
style => "MyTimeStyle"
);
Note that in this example, if 'fixed' was 'false' or undef, a fully
functional ODF editor could dynamically update the 'time value'
according to the current date and the text content according to the
current time and the given style. Here the internal value is a
'time value'; it would be the same for any field type containing a
time value (such as, say, a 'print time' or a 'creation time' field).
For other field types, the corresponding attribute would be
'date value', 'string value', 'boolean value', or just 'value'. For
any detailed information about the possible attribute combinations
according to the field types, have a look at the chapter 6 of ODF 1.1.
By default, the field is inserted at the beginning of the given text
element. But, thanks to the optional position parameters, it can be put
anywhere within the text of the element. The position parameters
are 'offset', 'before', 'after', 'replace', and 'way', and they work
like with setBookmark() and other methods. See also setChildElement()
in OODoc::XPath. If the 'replace' option is used, the matching substring
is deleted and replaced by the text field. The next example inserts
the name of the author of the last change (i.e. the 'creator', according
to the ODF vocabulary) as a replacement of a "AUTHOR HERE" substring
searched backward somewhere in a 50-character-long area at the end of
the target element:
$doc->setTextField (
$paragraph, 'creator',
replace => "AUTHOR HERE",
offset => 50,
way => 'backward'
);
and the code below appends after the last character of the paragraph a
'file name' field that will display the full path of the file:
$doc->setTextField (
$paragraph, 'file name',
offset => 'end',
attributes => {
display => 'full'
}
);
The last example creates a display area in a given paragraph after a
given substring for a declared variable whose name is "Amount" (see
setUserFieldDeclaration() in OpenOffice::OODoc::XPath to see how such
a variable may be declared):
$doc->setTextField (
$paragraph, 'variable',
name => "Amount",
replace => "AMOUNT HERE"
);setTextFields(element, expression, field-type [, options])
Replaces every substring that matches the given expression in the given
text element by a variable text field. See textField() in the present
manual chapter for some information about text fields.
This method works the same way as setTextSpans() to retrieve the strings
to be replaced. However, each matching string becomes invisible and
is replaced by the variable field.
Optional field attributes are allowed after the field type in the same
conditions as for textField().
The following example replaces every occurrence of "TIMESTAMP" in a
given section by a variable field displaying a time which is 2 hours
later than the current time:
$section = $doc->getSection("Variables");
$doc->setTextFields
(
$section, "TIMESTAMP", 'time',
'time-adjust' => 'PT02H'
);
This method returns the text field elements as a list.
See also setTextField().setTextSpan(path, position, style [, options])
setTextSpan(element, style [, options])
Inserts a substring with a special text style in a selected position
within the content of an existing text element (namely a paragraph or
a heading). Unlike setSpan() and setTextSpan(), inserts only one span
(or nothing if the conditions are not met).
A "text span" is a substring whose presentation style differs from the
style of the text element to which it belongs. For example, a given
"span" could be in italics while the rest of the paragraph is in normal
characters. A text span is a special element that contains text but that
must be included in a paragraph or a heading. Caution: the same word has
a different meaning when it's used about table cells (see cellSpan()).
The properties of a text span can be related to any kind of character
string presentation, such as font, font size, font weight, font
style, and colors (background and foreground). Whatever these
properties, they apply through a style.
setTextSpan() works on any kind of text container, whatever its
hierarchical level. For example, if the given element is a table,
the span style attribution applies to every cell of the table. And
the same change can be done in all the displayable content not
including page headers, page footers, and page backgrounds through
a single setTextSpans() call, if the given element is the document body
itself (see getBody() in OpenOffice::OODoc::XPath).
The first argument is the target element, the second one is the name of
a text style (existing of to be defined). The optional parameters that
follow specify how and where the text span should be inserted.
The method returns the new text span object, or undef in case of
failure.
The location of the text span may be specified using the same options as
the setChildElement() which is described in the OODoc::XPath manual.
A 'capture' parameter, whose value is a string, means that the first
substring that matches it should become the content of the new text
span. The following instruction replaces the first appearance of the
"ODF" substring in a given paragraph by a text span whose content will
be "ODF" and whose style will be "Standout"; in other words, it tells
that the style "Standout" will apply to the first "ODF" substring:
$doc->setTextSpan($paragraph, 'Standout', capture => "ODF");
It's possible to apply a text style and to change the text content in
a single operation using both the 'replace' and the 'text' options.
If 'text' is set, its value is used as the text of the new span element.
In the next example, the "ODF" substring will be removed and replaced
by a text span whose style will be "Standout" and content will be
"OpenDocument" instead of "ODF":
$doc->setTextSpan(
$paragraph, "Standout",
replace => "ODF",
text => "OpenDocument"
);
Note that there is no default text, so if 'replace' is set while 'text'
is not set, the matching substring is deleted and replaced by a text
span with a style but without content, resulting in useless markup
(there are more convenient ways to just delete a substring).
Practically, if both 'text' and 'capture' are set, the result is the
same as with 'replace'; however, as soon as the aim is to replace a
substring by a text span and not to capture the content of the substring
in the text span, I encourage the use of 'replace' in order to get a
more self-documented code.
It's possible to provide a search string with a 'after' or 'before'
option instead of 'replace'. If so, the new text span is inserted
after of before the first match, and no text is removed or moved into
the text span element, that may receive the value of 'text' (if set).
The example below creates a text span with the "Standout" style and
whose content is "OpenDocument" immediately after a the substring "the
best document format is ":
$doc->setTextSpan(
$paragraph, "Standout",
after => "the best document format is ",
text => "OpenDocument"
);
While the 'replace', 'after' or 'before' parameter automatically selects
the first match, it's possible to reverse the search, thanks to the
'way' option, whose possible values are 'forward' and 'backward'
(default='forward').
Caution: A substring located partly in a "span" and partly outside it
will never match. In addition, while a text span is allowed inside
another text span, a text span can not be spread across element
boundaries.
The 'offset' parameter is a positive or negative integer that specifies
the start position of the span in the text. So, this parameter allows
to insert a text span at an arbitrary position (counted forward from the
start or backward from the end).
If 'before', 'after' or 'replace' (which are mutually exclusive) is set,
the 'offset' option, if provided too, specifies a search space
restriction and a search way. If 'offset' is positive, the search space
runs from 'offset' to the end; if 'offset' is negative, the start
position is counted from the end and the search space runs backward
from the given position and the beginning of the context.
More generally, this method uses the logic and the search options of
setChildElement() to compute the insert point, like setAnnotation() and
other special intra-paragraph markup insertion methods;
setChildElement() is described in the OODoc::XPath manual page.
Remember that setTextSpan() creates only one text span with various
options; if the aim is to automatically create a text span for every
match of a given substring, see setTextSpans().setTextSpans(element, style [, options])
Applies a special text style to all the substrings of a given text
element that match a given expression. See setTextSpan() for
explanations about the meaning of "text span". The main difference
with setTextSpan() is that setTextSpans() unconditionally sets a
span for each substring that matches the given expression in the whole
target element.
The context element and the style to apply are provided as mandatory
arguments. They are followed by the named search parameters. These
parameters are the same as for setTextSpan(). Warning: the user must
ensure that the provided search parameters make sense and can't result
in an infinite loop. For example, the following instruction will
attempt to create an infinite sequence of continuous bookmarks before
the first occurrence of "xyz" substring, if this substring exists:
$doc->setTextSpans( # Wrong !
$paragraph, "SomeStyle",
before => "xyz"
);
Taking the following paragraph as an example:
"OpenOffice.org includes Writer, Calc, Draw and Impress"
Assuming this text is contained in a $p element, the following
instruction gives the "Highlight" style to the "OpenOffice.org",
"Writer", "Calc", "Draw", and "Impress" substrings:
$doc->setTextSpans(
$p, "HighLight",
capture => 'OpenOffice\.org|Writer|Draw|Calc|Impress'
);
The given context may be any element, including the whole document,
and not only a paragraph. This last example produces the same effect
as the previous one, but it operates between two given arbitrary text
bookmarks that may be in different paragraphs in the document, while
the context is the document body:
$doc->setTextSpans(
$doc->getBody(), "HighLight",
capture => 'OpenOffice\.org|Writer|Draw|Calc|Impress',
start_mark => $doc->getBookmark("BM1"),
end_mark => $doc->getBookmark("BM2")
);
See also setTextSpan(), removeSpan() and setHyperlink().setUserFieldDeclaration(name [, options])
Creates a user field declaration for the document. Allowed options
are:
'type' => the data type (default=string)
'value' => the initial value (default="")
Returns the new variable element if successful. Does nothing and
returns undef if the variable already exists. The example below creates
a declaration for a variable whose name="Amount", type=float and
value=1234.56
$doc->setUserFieldDeclaration(
"Amount",
type => 'float',
value => 1234.56
);
See also getUserField(), userFieldValue(), setUserFieldReference().setUserFieldReference(context, name [, options])
Puts a displayable user field reference somewhere is the content of a
text element. The first argument is the context (should be a paragraph
or heading element). The second one is the name of a user field
(existing or to be created using, for example, setUserFieldDeclaration).
Each user field reference in a document displays the value of the
corresponding user field declaration.
If the 'check' option is set to 'true', warns and does nothing unless
the user field declaration exists.
A 'style' optional parameter is allowed; if set, it must specify the
name of an appropriate format style according to the data type of the
user field declaration.
By default, this tableName(table [, newname])
Returns the current name of a given table, or replaces it with a new
name given as the second argument. The table can be indicated
by number, logical name or reference.
Returns undef unless the given table is defined.
If the new name is the name of an existing table, the table is not
renamed and an error message is produced.tableStyle(table [, style])
Returns the current style of a given table, or replaces it with a
new style given as the second argument. The table can be indicated
by number, logical name or reference.textBoxCoordinates(text_box [, new_coord])
Gets or sets the position of a text box. The new coordinates, if
any, must be provided using the same syntax and units as with
the "position" option in createTextBox().textBoxDescription(text_box, [, new_desc])
Gets or sets the optional description (long label) of the given
text box.textBoxName(text_box [, new_name])
Allows the applications to get the name of the given text box
(which makes sense if the name is unknown, i.e. if the first
argument is the element reference or the order number and not
the name itself, of course). If a literal is passed as a second
argument, the text box is renamed accordingly.textId(element [, text_id])
This accessor gets or sets the "text identifier", an optional
attribute of any text container. This attribute is presently used
for a few elements by OpenOffice.org (ex: the notes).
With one argument only, returns the existing identifier of the given
element, or undef if the element doesn't own a text identifier.
If a second argument is provided, its value replaces any previous
value of the identifier, and the text identifier is created if needed.
The new value is not checked, so the application should take care of
its uniqueness.
The text identifier can be used as a bookmark, knowing that, unlike a
bookmark, this attribute is not visible for the end user.
See also selectElementByTextId().
Caution: The text identifiers created or changed by other applications
are presently *not* preserved when the document is edited through
OpenOffice.org.textField(type [, options])
Creates and returns a variable field to be inserted within a text
element.
Such a field doesn't contain any static text by itself. When
included in a text container, it tells the editing/printing software
to display dynamic context data, such as date, time, file name,
page number, page count, author, etc. Variable text fields are mainly
used in page headers or footers, but they are allowed in the page
bodies as well. Remember that a text field must be attached as a child
element of a text container (paragraph or heading) in order to be
displayed. However, the text container itself may be attached to
anything anywhere (ex: a page header, a table cell, a list item, etc).
The first argument (mandatory) is the field type. Many field types
are allowed, so they are not all listed here. For some of them,
options are allowed or required.
To get the full list of field types, and their possible options,
look at the chapter 6 "Text fields" in the OpenDocument 1.0
specification. However, a few ones are presented below as examples.
The field type, as well as each field option, must be provided as it
appears in the OpenDocument specification, without the "text:" prefix
(this prefix is automatically added). However, the application can
force any arbitrary field name and/or field option such as 'xxx:yyy'
(any name or option including a ':' is accepted as is).
Caution: textField() allows the user to create any kind of field,
without OpenDocument compliance check. So it can be used to insert
application-specific markup in any place. This feature could prove
useful in some situations, but remember that a typo in a field type
or option will not be automatically detected. In the other hand, every
non-OpenDocument field is silently removed if the document is later
edited and saved through OpenOffice.org.
Knowing that the created element is not attached to a text container,
it must be inserted or appended through another method. For example,
the following sequence creates a paragraph displaying "This document
contains <page-count> pages and we are in the page <page-number>":
$para = $doc->appendParagraph
(
text => "This document contains ",
style => "Standard"
);
$pg = $doc->textField('page-count');
$doc->appendElement($para, $pg);
$doc->extendText($para, " pages and we are in the page ");
$pg = $doc->textField('page-number');
$doc->appendElement($para, $pg);
The 'page-number' field type, introduced above, could be adjusted in
order to display the page number of any following or preceding page.
To do so, a 'page-adjust' option, set with a positive or negative
integer value, should be provided to createField():
$pg = $doc->textField
('page-number', 'page-adjust' => -2);
Note that, if the arithmetic sum of the real page number and the
'page-adjust' value doesn't match an existing page, the editing
application should display nothing.
As another example, a 'chapter' field displays the current chapter
number or title. It requires 2 options: 'outline-level', an integer
which selects the hierarchical heading level to be regarded as the
chapter level, and 'display' which controls the value to display
(chapter number, chapter name or both). The following instruction
creates a field displaying the number and the name of the current
level 1 heading:
$chapter_field = $doc->textField
(
'chapter',
'outline-level' => 1,
'display' => 'number-and-name'
);
Other possible fields display the current date or time (see the
setTextField() example about a time field with an optional ajustment),
the author's name, the file path or name, and many other variable or
fixed values, according to many options.textStyle(path, position [, style])
textStyle(element [, style])
Reads the name of a text element's style or, if a 'style' argument is
given, changes it. The text element may be a section, paragraph, a
heading, or a text span included in a paragraph or a heading.
The element can be indicated by the pair [path, position] or by
reference.
The returned value is a literal style identifier, i.e. the value
of the element's 'text:style-name' attribute. This identifier could
be used to retrieve the style element itself, through another method
such as getStyleElement() (see OpenOffice::OODoc::Styles).
Note: this method allows you to attribute a non-existent style to a
paragraph or heading. Such a style can be created later (e.g. using
createStyle) or not at all. The actual existence of the style is
only relevant to the needs of the application. Obviously,
opening a document which contains references to non-existent styles
in OpenOffice.org will give unpredictable results as to the viewing
of the given paragraphs or headers.unlockSection(section)
Removes the write protection (if any) of the given section. If the
section was key-protected, the key is removed and provides the return
value of the method.
Example:
my $key = $doc->unlockSection("Section1");
$doc->lockSection("Section2", $key);
The two lines above remove the protection of "Section1" and protect
"Section2" with the password which previously protected "Section1".unlockSections()
Removes the write protection of every section in the document.updateCell(table, row, column, value [, text])
updateCell(element, value [, text])
Modifies the content of a table cell.
In its first form, indicates a cell by its 3D coordinates, as with
getTableCell(). In its second form, indicates a cell by its element
reference.
If the cell is set to literal, its content is limited to its text.
In this case, the optional argument "text" is of no use (the text
equals the value).
If the cell is set to numeric (float, currency, date, etc.), you
should generally pass a literal argument as well as the value.
This method can be replaced by cellValue() which allows reads and
writes.updateUserFieldReferences(user_field [, context])
Forces an immediate update of the display representation(s) of
a given user field, according to the actual value of the field.
It's possible to restrict the scope to a particular context, that
may be provided as an optional argument.OpenOffice::OODoc::Element methods
While all the methods above belong to the document object, some
additional methods are defined for individual text containers. These
methods belong to the OpenOffice::OODoc::Element class. The most
general of them are described in the OpenOffice::OODoc::XPath manual.
Some of them (listed below) are simple read-only accessors allowing
the user to check the type of any element.isXXX() methods
A set of "isXXX" methods, returning true or false, allow to check
the type of a given element. Caution, this methods belong to the
elements, not to the document.
Example:
print "This is a list" if $element->isItemList;
Here is the list of element type indicators:
isBibliographyMark bibliography mark (in the doc. body)
isCovered covered (invisible) table cell
isDrawPage presentation or drawing page
isEndnote endnote main element
isEndnoteBody endnote body element
isEndnoteCitation endnote citation element
isFootnote footnote main element
isFootnoteBody footnote body element
isFootnoteCitation footnote citation element
isHeading heading
isItemList list (ordered or unordered)
isListItem list item
isNote main note element (end- or footnote)
isNoteBody note body (in end- or footnote)
isOrderedList ordered list (OOo only)
isParagraph paragraph
isSection section
isSequenceDeclarations set of sequence declarations
isSpan span element (see setSpan)
isTable table
isTableCell table cell
isTableRow table row
isUnorderedList unordered list (OOo only)Other element methods
For a neater and more direct access to element types, see the
getName method of XML::Twig::Elt. A call to $element->getName
returns the element's XML name including its namespace prefix
e.g. 'text:p' for a paragraph or 'table:table-row' for a table
row. Remember that all the features of XML::Twig::Elt are
available for any text container.Properties
No class variables are exported.
Instance properties are the same as for OODoc::XPath, plus:
'delimiters' => delimiter table
hash giving the relation between element types and the delimiters to
use when exporting text (see getText).
'use_delimiters' => delimiter usage (see getText)
indicates whether delimiters are to be used by getText or not when
exporting text. Set to 'on' by default. Can be set to 'off' or
another value to stop or limit use of delimiters.
'heading_style' => default header style
indicates the default header style to be used by element creation
methods when no style is specified. Set to 'Heading 1' by default.
'paragraph_style' => default paragraph style
indicates the default paragraph style to be used by element creation
methods when no style is specified. Set to 'Standard' by default.
'field_separator' => field separator
contains the character string to be used as the field separator when
exporting tables. By default it is ";".
'line_separator' => line separator
contains the string to be used to separate lines when exporting
"flat" text. By default, it is a line-feed ("\n").
'max_rows' => max table length (default 32)
'max_cols' => max table width (default 26)
these 2 properties control the size of the "managed area" in a
spreadsheet; the default "managed area" is the A1:Z31 rectangle,
corresponding to the (0,0)-(31,25) coordinates; see getTable() and
getTableCell() and normalizeSheet() for more explanations.
'expand_tables' => table transformation usage
indicates whether the XML representation of the spreadsheets are to
be expanded in order to allow the same cell/row addressing scheme
as with the tables belonging to text documents; by default, this
property is not set. If this property is set to 'on', the first
access to any sheet will automatically trigger this transformation,
so the explicit normalizeSheet() method will not be needed.
However, this automatic (but costly) transformation has a drawback:
it uses the same 'max_rows' and 'max_cols' values for every targeted
sheet, whatever the really needed managed area for each one.AUTHOR/COPYRIGHT
