Error parsing a valid XML Schema

[Minh Kama Yie <mi...@nuix.com.au>]

Hi all,

I'm trying to parse a XML Schema document that is validated succesfully at 
the url: 
http://www.w3.org/2001/03/webdata/xsv

I'm using xerces 1.4.3 and running sun's jdk 1.3.1 on a linux box.
I'm currently doing a fairly simple parsing process, just:

            DocumentBuilderFactory builderFactory =  
DocumentBuilderFactory.newInstance();

            builderFactory.setValidating(true);

            builderFactory.setNamespaceAware(true);
            
            DocumentBuilder docBuilder = builderFactory.newDocumentBuilder(); 
         
            docBuilder.setErrorHandler(new MyHandler());            
            
            Document w3cDoc = docBuilder.parse(new InputSource(new 
StringReader(xsdString)));


However in doing this I generate the following error. From what I understand 
from reading the source code, it is a result of not being able to resolve the 
grammar for the xsd namespace, and the namespace keys in the list for the 
grammar resolver is empty. I can't quite interpret what to do about this 
however.

org.xml.sax.SAXParseException: General Schema Error: Grammar with uri: 
http://www.w3.org/2001/XMLSchema , can not be found; schema namespace may be 
wrong:  Xerces supports schemas from the "http://www.w3.org/2001/XMLSchema" 
namespace or the instance document's namespace may not match the 
targetNamespace of the schema.

	...

Would anyone know what I'm doing wrong? I've got a feeling its something 
bleeding obvious that I've missed....

Thanks in advance guys.
