Can HTML::Parser deal with this code? And do you really need to use XML::LibXML? If the answers are yes and no you can use HTML::TreeBuilder (and HTML::TreeBuilder::XPath for very usefull XPath support. Or use XML::Twig, which uses HTML::TreeBuilder to wrestle XML out of the HTML.

Othersiwe you could use HTML::Tidy, or just plain tidy, to clean-up the HTML before using it.

IIRC, the I was looking for a way to convert HTML to XML, HTML::TreeBuilder seemed to be the most robust parser available in Perl.
