Yes. Or STaX which is a new API available only for Java right now and
looks like it's a  bit easier to deal with than SAX.

libxml2 does have a SAX implementation so if I make it part of Emacs
then that would be available.

James Clark and I have already had a discussion about this on the
emacs-devel list. James is writing an XML parser in Emacs Lisp and
his view was that native Elisp is always going to be better than a
foreign library.

I take his point. But there are other reasons why I'd like libxml2
integrated into Emacs (because I use it everywhere else other than
Emacs) so I might do it anyway.
