METHODS
- $canon = XML::Canonical->new( comments => $comments );
-
Returns a new XML::Canonical object. If $comments is 1, then the canonical output will include comments, otherwise comments will be removed from the output.
- $output = $canon->canonicalize_string( $xml_string );
-
Reads in an XML string and outputs its canonical form.
- $output = $canon->canonicalize_document( $libxml_doc );
-
Reads in a XML::LibXML::Document object and returns its canonical form.
BUGS
Doesn't remove superfluous attributes begining with xml:
Doesn't check for relative namespaces.
NOTES
This module is in early alpha stage. It is suggested that you look over the source code and test cases before using the module. In addition, the API is subject to change.
This module implements the lastest w3 recommendation, located at http://www.w3.org/TR/2001/REC-xml-c14n-20010315 XML::CanonXMLWriter implements James Clark's Canonical XML definition.
