XML parsing memory overhead concerns

Though James Clark has explained how you can do what you want with
expat, you might be interested in LT XML.  LT XML was originally
written to handle large natural-language corpora, some of which are
several gigabytes.  It allows you to read "bits" sequentially, and
when you find a start tag that you are interested in, easily fill in
the tree rooted there.  It can also validate if desired (validation
requires memory to store a table of IDs and IDREFs, but still works
without building a tree).
