Simple XPath with namespaces not working

[pallibj]

Using input XML as:
<WG:R xmlns:WC="cNamespace" xmlns:WG="gNamespace" AF="22"><WG:F Id="22"/></WG:R>

Namespace resolver as:
` function Xml_NSResolver(strPrefix) {
if (strPrefix == "WG") {
return 'gNamespace';
}
else if (strPrefix == "WC") {
return 'cNamespace';
}

return null;

}`

The script initialized by:
mobjXpathEngineWindow = { document: {} };
wgxpath.install(mobjXpathEngineWindow);

Then calling evaluate as:

• evaluate("//WG:F[@id='22']", objContext, Xml_NSResolver, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null) - no results
• evaluate("//WG:F[@*[local-name()='Id']='22']", objContext, Xml_NSResolver, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null) - no results
• evaluate("//[local-name()='F' and namespace-uri()='gNamespace'][@[local-name()='Id']='22']", objContext, Xml_NSResolver, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null) - no results
• evaluate("//[local-name()='F'][@[local-name()='Id']='22']", objContext, Xml_NSResolver, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null) - Gives results, but doesn't distinguish namespaces so unusable.

All the above xpath queries work fine in online xpath testers.

Attached is a fully contained test.html for these tests.
