RELAX Verifier for Java checks whether an XML document is valid against the given REgular LAnguage description for XML (RELAX) syntax. The Full Version link downloads a distribution of RELAX Verifier that includes the IBM XML4J package. If you already have SAX and DOM parser, the Lightweight Version link downloads a smaller distribution without IBM XML4J. This page also includes a short tutorial.
