I have not had problems with XML::LibXML's documentation.

It all depends on the use you have, if its large documents, I would encourage a SAX-based parser, XML::Parser::ExpatXS, which is really fast. If its small documents, The DOM interface will work just fine, specially when you need to perform validation (DTD, Schema, RelaxNG, etc.).

With the DOM doc in memory you can perform XPath searches, which is fast, again for small docs.

You might also want to take a look at XML::Rabbit, which uses Moose and allows you to build Perl objects from XML docs.

Any of these approaches will work for you, you would have to share some of your requirements for me to give you more guidance.. is it performance? code readability/maintainability ? system constraints?
