Re: testing child elements for text

I need to see if an element has children that contain data....

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
