Thank you again. I took the day and tossed my old code, and wrote a new 
reader that inherited from OpenLayers.Format.XML and it was pretty 
straight forward. New code works great and it much cleaner than my old 
hack. I'm not sure why I did not do this in the first place ... oh well!

Reading through OL code and the API, I see that concatChildValues() is 
depreciated and it points to getChildValue() which appears to only get 
the first child.

Is getChildValue() doing something tricky that I missed?

I also see getChildEl() and getNextEl() which might be used to loop 
through the children to concat the results.
