Verifying a document against a specific DTD with JDOM

[Brian J. Sayatovic]

I have a situation where I'm received XML with no DOCTYPE over HTTP.
However, this XML is supposed to conform to a DTD which I have
locally, so I'd like to be able to verify the incoming MXL stream
against the DTD.

Right now, I'm using JDOM b9 with a custom JDOMFactory to construct
cusotm Element subclasses for certain elements. I have not found
anything in the API that leads me to believe that I can specify to the
SAXBuilder a specific DTD to use.

As near as I can tell, JDOM's SAXBuilder uses an underlying "SAX
Driver" to feed it SAX events and construct the resulting DOM. In my
case, I Xerces is the underlying SAX parser. And, again, as far as I
can tell, I also can't force it to verify a document against an
arbitrary DTD.

Any ideas?

Brian.
