++ to XML::Twig; I was also surprised to find XML::Simple as the only Perl module listed in the poll. I've been using XML::Twig ever since some more experienced monks (Your Mother, toolic) guided me in this area, and it's not let me down. It also comes with the very handy xml_grep and xml_pp (pretty-printer), which find frequent use at work.
I'm one of those "Java people" and I regularly deal with XML. I don't understand all the hate for it; after all, the very content you're reading right now was delivered to your computer using a form of XML. Right tool in the right place and all that.
