XalanNodeList and Xerces DOM

1. Create a XercesDOMParsedSource using XalanTransformer::parseSource
2. Call XercesDOMParsedSource::getDocument()
3. Call ::getChildNodes() on an element in that document
4. Every Node in that XalanNodeList is NULL (but the list size is
correct)

Is this expected behavior? Tracing through
XercesDocumentBridge::mapNode, I noticed:
- theXercesNodeImpl != 0
- m_nodeMap.getNode(theXercesNodeImpl) => 0
- m_mappingMode = false

Which leads to the NULL result.

Cheers,
Brian

Hi Brian,

Sounds like a bug.  Since we never use getChildNodes() internally (it's not
even supported in our default source tree), I'd bet it's never been tested.
Can you create a Bugzilla report and attach a small source code example
that reproduces it?

Thanks!

Dave
