I'm not a JAXP expert, but I play one on mailing lists.  I checked the
javadoc of the Node class and it looks as if it's behaving as
documented: the nodeValue of an element node is null.

http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Node.html

see the table in the introduction.

After much futzing around I realized that the data is a child node and 
then things got better. Thanx for the help.
