XML::Liberal - Super liberal XML parser that parses broken XML
use XML::Liberal; my $parser = XML::Liberal->new('LibXML'); my $doc = $parser->parse_string($broken_xml); # or, override XML::LibXML->new globally use XML::LibXML; use XML::Liberal; XML::Liberal->globally_override('LibXML'); my $parser = XML::LibXML->new; # isa XML::Liberal # revert the global overrides back XML::Liberal->globally_unoverride('LibXML'); # override XML::LibXML->new globally in a lexical scope { my $destructor = XML::LibXML->globally_override('LibXML'); my $parser = XML::LibXML->new; # isa XML::Liberal } # $destructor goes out of scope and global override doesn't take effect my $parser = XML::LibXML->new; # isa XML::LibXML
XML::Liberal is a super liberal XML parser that can fix broken XML stream and create a DOM node out of it.
This module is ALPHA SOFTWARE and its API and internal class layouts etc. are subject to change later.
$parser = XML::Liberal->new('LibXML');
Creates an XML::Liberal object. Currently accepted driver is only LibXML.
XML::Liberal->globally_override('LibXML');
Override XML::LibXML's new method globally, to create XML::Liberal object instead of XML::LibXML parser.
This is considered so evil, but would be useful if you have existent software/library that uses XML::LibXML inside and change the behaviour globally to use Liberal parser instead, with a single method call.
For example, the following code lets XML::Atom's parser use Liberal LibXML parser.
use URI; use XML::Atom::Feed; use XML::Liberal; XML::Liberal->globally_override('LibXML'); # XML::Atom calls XML::LibXML->new, which is aliased to Liberal now my $feed = XML::Atom::Feed->new(URI->new('http://example.com/atom.xml'));
If you want the original XML::LibXML->new back in business, you can call globally_unoverride method.
XML::Liberal->globally_override('LibXML'); # ... do something XML::Liberal->globally_unoverride('LibXML');
Or, you can hold the destructor object in a scalar variable and make the global override take effect only in a lexical scope:
{ my $destructor = XML::Liberal->globally_override('LibXML'); # ... do something } # now XML::LibXML::new is back as normal
This module tries to fix the XML data in various ways, some of which might alter your XML content, especially bytes written in CDATA.
