xalan DOM document

[Jim Maskus <jm...@collegenet.com>]

Hello,
I'm performing a sequence of transforms on a single source document in 
a xalan pipeline using SAXsource and SAXresult. To make the pipeline 
more intelligent I'd like to peek in the source DOM (if there's one?) 
to see which transforms in the pipeline need be executed. My question 
is in xalan is a DOM tree created by an XMLReader or other part of the 
process or do I have to set up my own DOM tree to query as in the 
ApplyXPath and ApplyXPathDOM examples. Any enlightenment is greatly 
appreciated.

Jim
