NAME
XML::Toolset::LibXML - Interface to LibXML toolset
SYNOPSIS
my $toolset = new XML::Toolset::LibXML(%options);
if ($doc = $toolset->validate($xml)) {
... Do stuff with $doc ...
} else {
print "Document is invalid\n";
}
DESCRIPTION
XML::Toolset::LibXML is an interface to the LibXML validating parser which can be used with the XML::Toolset module.
METHODS
- new(%options)
-
Returns a new XML::Toolset::LibXML instance using the specified options. (See OPTIONS below.)
- validate($xml)
-
Returns a true value if $xml could be successfully parsed, undef otherwise.
Returns a true (XML::LibXML::Document) if $xml could be successfully parsed, undef otherwise.
- last_error()
-
Returns a hash ref containing the error from the last validate call. This backend currently only fills in the message field of hash. Note that the error gets cleared at the beginning of each
validate
call. - version()
-
Returns the version of the XML::LibXML module that is installed
OPTIONS
XML::Toolset::LibXML takes the following options:
- validation
-
If this boolean value is true, the document will be validated during parsing. Otherwise it will only be checked for well-formedness. Defaults to true.
- schema_location
-
Since the XML document is supplied as a string, the toolset doesn't know the document's URI. If the document contains any components referenced using relative URI's, you'll need to set this option to the document's URI so that the toolset can retrieve them correctly.
ERROR REPORTING
When a call to validate fails to parse the document, the error may be retrieved using last_error.
On errors not related to the XML parsing, these methods will throw exceptions. Wrap calls with eval to catch them.
DEPENDENCIES
XML::LibXML
BUGS
last_error currently returns a hash ref with only the message field filled. It would be nice to also fill the line and column fields.
