Got it! I tracked it down in "Java & XML" by Brett McLaughlin,
published by O'Reilly.
BTW, the book makes use of Apache Xerces in its examples and that's
what I used.
Thanx,

The following xml text is what gets returned from the web service call.
I have tried a variety of methods to extract the values, as shown in
the included client source, using examples found on the web but with no
success. They all return the OMElement from the web service invocation
as a string with no children or siblings. Eclipse, however, seems to
understand the text as xml just fine, allowing me to use the graphical
view to view the elements and their values.
What tool(s) should I use to extract the values?
Thanx,
Garth
