xerces2_6_2 validating using dtd and schema. please help

[mmartinh]

Hi I am having trouble validating an xml document using xerces2_6_2

I have a DTD that containes only entity references, and a schema that is used to ensure the xml is valid.

I get this error.

Element type "my root tag" must be declared!

It seems to expect all validation grammer to be in the dtd. I have sucessfully validated with xml spy and oxygen,(oxygen uses xerces too).

This is a real pain I really would lie to take advantage of using schemas, I know I could just use entity references in this form   and not have a dtd but this is really not acceptable.

I have tried out all the xerces specific properties and features but this has not worked either.

Perhaps I should implement a validator? Does anyone have any ideas?

thanks

Hi I have now found the answer, I made the asumption that the only poperties and features to be set for xerces were on the xerces site.

However setting ...

parser.setProperty("

http://java.sun.com/xml/jaxp/properties/schemaLanguage","http://www.w3.org/2001/XMLSchema");

allows schema only validation.
