Hi, Mark:
As a footnote on the suggestion from Chris, you should be able
to get elements without child elements this way:
/xh:BOOKS//*[empty(*)]
and elements without any child nodes this way:
/xh:BOOKS//*[empty(node())]
If I recall correctly, documents with a known schema can have
insignificant whitespace that doesn't count as a node, but I may be
misremembering the rules for insignificant whitespace.
Hoping that helps,
Erik Hennum

If you just want to get the elements below BOOKS:
/xh:BOOKS/element()
or, for all nodes
/xh:BOOKS/node()
