It sounds like you are asking too much of java. I may be wrong, it's powerful 
in some ways, yes, but rarely powerful and fast at the same time.

If you post a link somewhere to an example of the document, I'm sure there are 
a stack of folks from a stack of companies that might give it a crack and 
come back with some commercial offers to help out.

I could even tell you how fast I can process each of the nodes, and others 
might even offer to do the same.

Otherwise, a very simple thing to do might be to get a local contractor with a 
fair degree of experience to give assistance.

Handling events on nodes in realtime within an xml document is a specialist 
task at the moment. Either have fun with more tinkering, or try one or more 
of the above.

Best Regards

David
