TREX-Q : A query language based on XML Schema


TREX-Q is an off-shoot of work done by James Clark on an XML validation language called TREX. For an abstract outlining our work on TREX-Q, click here. The full paper as published in the 2001 conference for Linguistic Databases at UPenn is here in pdf format.

I strongly suggest you start by becoming familiar with TREX proper by reading through the TREX tutorial.

After that, then you should read the TREX-Q tutorial that desribes the additional features added to TREX-Q from TREX proper.

Then you can try the language out for yourself by downloading the sample implementation coded by extending James Clark's code written in Java.
