check if string is empty

I have an XML document that may contain nodes with no children


in the XPath data model that node does contain a child, a text node
consisting of a newline and 6 spaces.

This is a VFAQ, the answers are

test="not(node())"  (tests if really empty)
test="not(*)"  (tests if no element children)
test="string(.)" (tests if string value is empty)
test="normalize-space(.)" (tests if string value is just white space)
