ta, I did contemplate the GetChildren methods.
Due to time pressures, and a very specific need, I resorted to modifying 
the xml file via string manipulation.

If I ever need to revisit I may look to do it better, either within my 
code or extending the component.
Would XPath fit within the gb.xml component, or would you imagine a 
gb.xml.xpath component?
