I don't really understand why you need/want to use regexps for this...

Anyway, there is something similar on IBM's alphaworks site. It's
called 'XML Generator' and seems to works with DTDs instead of
Schemas, but maybe it could still be useful or give you ideas:

    "IBM's XML Generator is a Java program that creates test cases for
    XML applications by generating "random" instances of valid XML
    from a single document-to-document (DTD) input."

The web page is:
