Validating with external DTD

	Hi,
		Sorry for asking XML Question in this mailing list. I have
searched in lot of places
	But could not found the information.
		I have an XML file that has no DOCTYPE decleration in it.
But I have to validate it with 
	DTD. I am using Xerces C++. Is there is any way to do that with out
editing the XML file.
	(like setting DocumentType before parsing).

	Any help will be greately appreciated.


	Thanks,
	Raj
