###########################DESCRIPTION
This documentation is written to explain ways to use this module when writing your own excel parser. To use the general package for excel parsing out of the box please review the documentation for Workbooks, Worksheets, and Cells
This is the Zip file adaptor for reading the workbook meta file 'xl/workbook.xml'. The file has several default sets of information that should be gathered. They can all be retrieved post file initialization with Methods. The goal is to standardize the outputs of this metadata from non standard inputs.
Required Methods
These are the methods required by the role. A link to the default implementation of these methods is provided.
"advance_element_position( $element, [$iterations] )" in Spreadsheet::Reader::ExcelXML::XMLReader
"parse_element( [$depth] )" in Spreadsheet::Reader::ExcelXML::XMLReader
"start_the_file_over" in Spreadsheet::Reader::ExcelXML::XMLReader
"close_the_file" in Spreadsheet::Reader::ExcelXML::XMLReader
"squash_node( $node )" in Spreadsheet::Reader::ExcelXML::XMLReader
"good_load( $state )" in Spreadsheet::Reader::ExcelXML::XMLReader
Methods
These are the methods provided by this role (only).
load_unique_bits
Definition: This role is meant to run on top of Spreadsheet::Reader::ExcelXML::XMLReader. When it does the reader will call this function as available when it first starts the file. Therefore this is where the unique Metadata for this file is found and stored. (in the attributes)
Accepts: nothing
Returns: nothing
get_epoch_year
Definition: returns the parsed epoch year that should be found in this file
Accepts: nothing
Returns: (1900|1904)
get_sheet_list
Definition: returns the full array ref containg all discovered sheets in the file. This will include worksheets and chartsheets.
Accepts: nothing
Returns: an array ref of strings
get_rel_lookup
Definition: returns the hashref with relId's as keys and the sheet name as values
Accepts: nothing
Returns: a hash ref with $relId => $sheet_name combos
get_id_lookup
Definition: returns the hashref with sheet id's as keys and the sheet name as values. I beleive that Sheet ID's are the id number used in vbscript to identify the sheet.
Accepts: nothing
Returns: a hash ref with $sheetId => $sheet_name combos
