It's possible, although not terribly pretty or efficient.  However, this
really isn't the appropriate forum for processor-specific questions.  You
can always subscribe and post to the Xalan-C Users list:

   http://xml.apache.org/mail.html#xalan-c-users

Note you can also get the output as an instance of the Xerces-C DOM, if the
transformation produces a well-formed XML document.  See the samples for
more information.
