I just found another utility that is based on XQL:

http://www.cs.york.ac.uk/fp/Xtract/

The author describes it thus:

"Xtract is a command-line tool for searching XML documents. Just as `grep'
returns lines which match your regular expression, so Xtract returns all
those sub-trees from XML documents which match a query pattern. The query
expression language is simple but powerful, and is based loosely on XQL,
the recently proposed XML Query Language. An introduction to the Xtract
query pattern language, together with the full Xtract grammar is in this
tutorial."

"The major difference from XQL is that a query must return a sequence of
XML contents (either elements or text inside an element): it cannot for
instance return just an attribute value."

Looks useful.
