Very impressive, as usual.

I do have a concern/question: what is the overhead of XPath parsing in 
these cases vs coding the queries in Java using the VTDNav class? I 
think I remember you posting before that the overhead was negligible, 
but I wasn't sure in what context or what circumstances this was the case.

If you have any additional comments in this regard I'd appreciate 
reading them. In particular, if you had any performance tips using the 
XPath evaluator that would be great.

Also, I have just found out about XMLModifier. Do you have any example 
code that shows how best to use this class? Not that it looks difficult 
- I'm just incredibly lazy and just want to copy/paste code that sets up 
the VTDNav and calls bind() appropriately. :-)

I couldn't find a way to create a masterDocument with a specific 
character set or other prologue data...(mainly so I can just use 
updateToken(int, String) ).

It would also be interesting to see how well XMLModifier benchmarks 
against xerces.

Cheers.
