[JXPath] Performance

[th...@ascentialsoftware.com]

I did a couple of searches in the mailing list and on the web to try to et
performance information on JXPath.
I did not find too much result, so I am asking the question directly to the
mailing list.
Anyone is any kind of performance numbers/comparisons between JXPath and
other Xpath processors that they could share?

More specifically, here is what I am looking for. Assuming that I have an
application processing XML documents. This application manipulates XML
documents themselves (string and DOM representation) as well as a Java bean
object tree representing those documents (typed/dedicated tree for each type
of document).
If I need to do some Xpath processing on those documents, what will be the
fastest: using something like Xalan to apply Xpath on the DOM tree or using
something like JXPath on the java bean object tree?

Thanks.
