[jdom-interest] How to manipulate a very large XML file? Any suggestions?

[Jason Hunter]

They stopped at XPath: "At the present time Xindice uses XPath for its 
query language".  It's too bad.  There are a lot of open source engines 
out right now.  Qizx/open looks most compatible with the spec (based on 
BumbleBee).  None of the open source engines I've tried can really scale 
though.  I need to add some scalability tests to BumbleBee to quantify 
these things.
