The document discusses XML::Liberal, a Perl module that allows XML parsers to successfully parse XML documents that contain errors. It provides examples of how XML::Liberal can be used to override an existing XML parser like XML::LibXML to make it more liberal in parsing invalid XML. It also shows how XML::Liberal can be used to try parsing XML with a fallback parser if the primary parser fails due to errors in the XML.
