There are two different XML based query languages. One is the W3C language XML-QL
The second one is 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
