I would suggest that if you do have time, you
investigate both using VTD-XML, and a Stax
implementation (such as http://woodstox.codehaus.org).
My feeling is that it all comes down to which one API
you feel more comfortable with, or perhaps whether
have to use a xml-compliant standard-based solution or
not.
Both can perform well enough, assuming you are not
limited by VTD-XML due to main memory requirements.
Stax memory usage is not linear with document length,
so there are no practical input size limitations.

If you do end up both approaches, it would be very
nice to get the performance numbers, since this would
be an actual real-world use case, instead of
benchmarks. Plus if code is simple enough, perhaps it
could become a benchmark for these types of
operations?

You are correct here. While limit is much higher than
with, say, DOM (2x or perhaps 3x), there is a limit.
