Xmlns presence prevents e4x access to XML data

Question

I have been pulling my hair out trying to simply access data
within a tag from an XML object. When I remove the xmlns attribute
it works, otherwise it doesn't. In the code below when I remove
"xmlns=http://xyz" the List displays the data. What do I need to
add to keep this xmlns in the XML and still populate the List box?
Thanks, JH

Try declaring a default namespace. This is at the instance
socpe level:
default xml namespace = "
http://xyz";
