[news.eclipse.webtools] Getting the Node given an ITextRegion

[David Carver <dcarver@xxxxxxxxxxxxxxxx>]

Is there a way to get the DOM node of a StructuredDocument, given a 
ITextRegion.

I've tried the following, but I'm not getting the Attribute Node or the 
DOM node I would expect:

	public static IDOMNode getNode(IStructuredDocumentRegion 
documentRegion, ITextRegion textRegion) {
		IStructuredModel sModel = 
StructuredModelManager.getModelManager().getExistingModelForRead(documentRegion.getParentDocument());
		IDOMDocument documentNode = ((IDOMModel) sModel).getDocument();

		return 
(IDOMNode)documentNode.getModel().getIndexedRegion(documentRegion.getStartOffset(textRegion));
	}

In particular, if I'm in an Attribute Value region, I would like to 
return the DOM Node for the attribute, or at least get the TextNode for 
the attribute.  However, the last is something that I don't think is 
implemented right in the WTP DOM implementation, as attributes aren't 
returning nodes even though the DOM Level 1 spec says they can have Text 
Nodes or Entity Nodes.   If it returned the value as a TextNode, then it 
would be a matter of just getting the parent Node.

Anyways, what is the correct way to get the information I'm looking for?
