Parsing against a specific DTD

[Iban Torres]

Hi all           How do you parse a XML document against a specific DTD, not the one that is defined in the xml DOCTYPE tag?. The problem is that if I generate a XML file with a DTD in one client and I want to get the DOM in the server the DTD file could has another path, so I have to be able to specify the DTD file before parse the XML Document. Of course I need validation. I have tried to find it in the APIs, but no way.   Any idea?   Thanks in advance.
