It sounds like the DOM implementation that you're using (probably stree)
just does not support the getAttributeNode(..) call. The stree DOM
implementation was designed to support XSLT and was not intended as a
full DOM implementation so it does not support all of the DOM calls.
It does support getAttribute(...) which might get you what you need.
Have a look at the class of nList.item(0) to see what DOM implementation
you're using.
