There are two different XML based query languages. One is the W3C language
XML-QL (
http://www.w3.org/TR/1998/NOTE-xml-ql-19980819/.
The second one is
XQL (
http://www.ibiblio.org/xql/).
In addition, there are few different opinions if XPath (
http://www.w3.org/TR/xpath) can be considered, or not, an XML Query language. This is mainly based on the fact that being
"[...] a language for
addressing parts of an XML document. [...]", it does much of what a query
language should (and would) do.
An interesting reading, anyway, is this article (from the W3Consortium):
Ten Features Necessary for an XML Query Language.
