RE: accessing (xml) objects from xsl

I was using Saxon 6.5.2 and could not get points 1 nor 2 working below. I tried it with Xalan-J 2 and point 2 below now seems to work.

These questions arised from the process of trying to use xsl templates that were created with the MSXML 3.0 XSLT processors and as such we were using their addObject() functionality and passing a DOM tree to be used in the xsl sheet the following way:

stylesheet tag:
====
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:preprocessors="urn:pre-process">
====

a parameter using it:
====
<xsl:param name="someparam" select="preprocessors:get-selectNodes('PREPROCPROCESSORS/SOMEPATH/FILE')" />
====

Question is: is it possible to get this working (using custom extensions?) with either Saxon or Xalan-J?

Thanks!
Sean.

The interface between XSLT and Java depends on which XSLT processor you
are using. So you'll need to identify the processor before anyone can
answer the question.
