PyTREX is an implementation of Tree Regular Expressions for XML (TREX) in Python. This first release includes basic support for the concepts described in sections 1 through 6 of the TREX tutorial.

The author, James Tauber, would very much appreciate feedback. If bugs are found, please e-mail the TREX file and instance you used to him directly, and he'll fix the bug personally and add the document to the test suite.
