Experimental support for W3C XQuery is available in Fatdog's XML Query Engine 1.0, and Software AG have released QuiP, an W3C XQuery prototype implementation.

Announcing the 1.0 release of XML Query Engine, a Java-based search component for small to medium-sized collections of XML document, Howard Katz of Fatdog noted also that "early experimental support" for XQuery is included. XML Query Engine currently uses XQL as its query language; the engine is small (~160K) and can easily be integrated into SAX applications.

For Software AG, XML querying guru Jonathan Robie announced the release of their XQuery prototype, QuiP. Usable against either Software AG's Tamino database or against normal XML files, QuiP can be downloaded from the developer section of Software AG's web site.

Robie writes:

This distribution is a good way to get a hands-on grasp of the XQuery language - it conforms to the 7 June 2001 draft of XQuery, and it includes a large number of sample queries and data files, syntax diagrams in the online help, and a GUI.

A forum for discussion of the product is also available via a link from the download page.
