I disagree. Few parsers track byte offsets or other locational info in
the file, and I think you need that to do basic things like proximity
and phrase search.

I think you do need to build your own engine. Reason is, most existing
search engines have an atomic-document view of the world, and break
down completely when asked to model a general recursive hierarchical
structure like XML. -Tim
