Yes, you can do this. There have been several previous discussions about this on this list, and the xalan-c user's list, so you might want to search the archives for more info.
It involves using the Xerces DOM and Xalan's wrapper around it, so it's much less efficient. Here's a post from the archives to get you started: http://marc.theaimsgroup.com/?l=xalan-c-users&m=101552175609344&w=2 When I have some spare time ;-), I'd like to do a sample for this, but I'm really backed-up right now.

The problem is that parsing the source document the way it is done in XPath API samples gives a readonly document, so in step 3 I have to construct a new document and feed it back to Xalan, which makes code slow and complicated. Is there any way to evaluate Xpath expressions on a writeable document in Xalan? BR --Sergey Petrunia
