XML::LibXML can do it as well, as was shown
here in this very thread.
XML::LibXML::Reader works similarly to
XML::Twig - it doesn't keep the whole data in memory, but if you tell it to, it can "inflate" a part of the data into a full-featured
XML::LibXML™ object you can process using all the available methods.
