It depends on what you wish to acomplish:
from ajt's answer to similar question:

Perl has many other excellent XML tools (including):

XML::LibXML and XML::LibXSLT are also c based, and very fast - a particular favourite
XML::DOM if you need a W3C DOM interface
XML::GDOME if you need a DOM level 2 iterface
XML::Parser if you want low level access to your XML
XML::Sablotron another fast c based parser/XSLT engine
XML::Simple a classic simple interface to XML in Perl
XML::TreeBuilder a useful yet underused XML tree manipulation module
XML::Twig another Perlish XML interface
