XalanSimplePrefixResolver and XPath

Hi.  I'm tring to use Xalan's XPath support to run queries on some  
Collada documents I have.  I've run into the issue that the documents  
all declare themselves in an anonymous namespace:
        <?xml version="1.0" encoding="utf-8"?>
	<COLLADA xmlns="http://www.collada.org/2005/11/COLLADASchema";  
version="1.4.0">
                <asset>
                ...
                </asset>
        </COLLADA>
        
So I want my XPath expressions to refer through that namespace.  I  
thought I'd try using the XalanSimplePrefixResolver doing something  
like this:
        XalanSimplePrefixResolver thePrefixResolver(
                                  XalanDOMString("c"),
                                  XalanDOMString("http:// 
www.collada.org/2005/11/COLLADASchema"),
                                  XalanDOMString("http:// 
www.collada.org/2005/11/COLLADASchema")
                                  );
        XPathEvaluator  theEvaluator;

        // OK, let's find the COLLADA root node...
        XalanNode*      theContextNode = theEvaluator.selectSingleNode(
                       theDOMSupport,
                       theDocument,
                       XalanDOMString("/c:COLLADA"),.c_str(),
                       thePrefixResolver);


But all I get are exceptions:
        XSL exception: The prefix 'c' is not declared.
        
Now, I'm clearly guessing on the declaration of the XalanSimplePrefix  
resolver, as I don't know the difference between the URI and the  
NamespaceURI parameters to the constructor.

What am I doing wrong?  If I ditch the xmlns declaration out of my  
xml file (and ignore the resolver...) all is fine.

Thanks,

Paul
