What is a way to test if the parent element has any children that actually
have data?  I will only process the parent if it has children that contain
data.

What does "having data" mean? No content (text, elements, whitespace, XML comments): test="not(*[node()])" No text, whether directly or in any descendant nodes test="not(*[string()])" No non-whitespace text, whether directly or in any descendant nodes test="not(*[normalize-space()])" No element nor text, but XML comments allowed test="not(*[text()|*])" No element nor non-whitespace text test="not(*[text()[normalize-space()]|*])" There are a few combinations more, check the list archive (this has just been discussed today)
