Hi Henry,
thank you very much for your help.

We wouldn't like to change our stylesheets because we have so many developed
previously and we would have to change them for all our customers.
I read the article at
> https://issues.apache.org/jira/browse/XALANJ-2057

Is there any possibility to wrap a DOMSource in another object so I can pass
it as node-set as Parameter?
I have tried to adapt the code at this page to our requirements:

  DOMSource domSource = new DOMSource(node);
  XSLTCDTMManager mgr = new XSLTCDTMManager();
  DTM dtm = mgr.getDTM(domSource, false, null, true, true);
  int dtmRoot = dtm.getDocument();
  DTMAxisIterator iter = dtm.getAxisIterator(Axis.SELF);
  iter.setStartNode(dtmRoot);
  DTMIterator iterator = new OneStepIterator(iter, Axis.SELF);
  iterator.setRoot(dtmRoot, new XPathContext());
  XNodeSet xNodeSet =  new XNodeSet(iterator);
  transformer.setParameter("Node", xNodeSet);

I couldn't test this because I always get a NullPointerException:

   java.lang.NullPointerException
	at
org.apache.xpath.axes.ChildTestIterator.setRoot(ChildTestIterator.java:125)
	at org.apache.xpath.axes.OneStepIterator.setRoot(OneStepIterator.java:92)

So, I don't know if I have misunderstood you or might this be the right way?

Thanks a lot in advance,
Ulrich Heeger
