Can I pass DOM from the Xalan XSLT processer to a Java

Hi

I have seen that using the xmlns:java="http://xml.apache.org/xslt/java" it is 
possible to invoke methods on java objects from within an XSL 

template, for example:

<xsl:template match="/language/text()">
   <!-- invoke a static method passing in the text node -->
   <xsl:value-of select="java:com.LSLocale.getJavaString(.)" />
</xsl:template>


Is it possible to pass actual DOM from the XSL processor back to a java 
object?  An article at Javaworld.com
http://www.javaworld.com/javaworld/jw-12-2001/jw-1221-xslt-p2.html
states that "Any Xalan extension function can also take NodeLists or Nodes as 
arguments and return these types to the XSLT processor".  The article 
demonstrates passing a Node to the XSLT processor but not taking one as an 
argument as I am trying.  So I tried: 

<-- object instance reference -->
<xsl:param name="DOMExtractor" />

<xsl:variable name="tree">
<a>
 <b>
  <c>
   <d/>
  </c>
 </b>
</a>
</xsl:variable>

<xsl:template match="root/blah/" >
  <!-- pass the node to the object -->
  <xsl:value-of select="java:setDataValue( $DOMExtractor, $tree )" />
</xsl:template>


Indeed I end up getting back is a org.w3c.dom.traversal.NodeIterator, 
specifically a org.apache.xml.dtm.ref.DTMNodeIterator.
But when I call the NodeIterator methods to get a Node such as getRoot(), or 
nextNode() NullPointers are thrown.  I could cast to the DTMNodeIterator but 
I have examined the object & it appears to be a flat representation of the 
tree, not DOM.

Anyone know if there a way to get a DOM Element out of xalan?

I'm using
Xalan 2.4.D1
jdk 1.3.1
