XmlSchemaCollection and schema imports question

[Jiho Han]

I am trying to validate a document against a set of schema [they are part
of a wsdl] and in order to do that, I am using XmlValidatingReader.Schemas.Add
to add the schemas.
However, since there are dependencies, the framework is crapping out (technical
term) saying that the referenced type is not available. Well, the type is
defined in the other schema which it imports. How do I get these schemas
in there first and then have it validate so the reference is not checked
until all the schemas are loaded?

BTW, this is on .NET 1.1.
Thanks

Do you have access to the WSDL and to the schemas it references?

If so, you can load the WSDL into a ServiceDescription object. This will
give you access to the schema locations by following the wsdl:import and
wsdl:types/xs:schema elements. You can then load them into XslSchema objects
using an XmlUrlResolver configured to permit access to the domain of the
schemas.

Actually, I am loading the wsdl by using ServiceDescription class.
I haven't used XmlUrlResolver.
Would you have any sample code for this? (even if pseudo)

Thanks
