XML::GDOME is actually a wrapper around libgdome which is a wrapper around libxml2, so it’s no surprise that it supports the same things. libgdome adds full DOM Level 2 support on top of libxml2 (including the Events stuff and such); unless you need that (which few people probably do), you can just use XML::LibXML. The code you’ll write is identical in both cases.
