I guess that's what XML::Twig (http://www.xmltwig.cx) was designed for.

XML::Twig is a Perl module that allows you to process sub-documents, one
at a time, building a tree for each one, then discarding it when you are
done with it. You can also define elements for which you want the tree
built (you just define the root of the sub-trees, you cannot build a
"view" of the document, although that could be an interesting

The interface is not DOM though, it is more perlish.
