goog.dom.xml is broken on MSIE9

[GoogleCodeExporter]

What steps will reproduce the problem?
1. var doc = goog.dom.xml.loadXml('<a><b><c>d</c></b></a>');
2. var aNode = doc.firstChild;
3. goog.dom.xml.selectSingleNode(aNode, 'b');

What is the expected output? What do you see instead?

Expected return value is a node element (b node). Instead, it returns null.

What version of the product are you using? On what operating system?

closure-library from trunk. Windows 7 using MSIE9.

Please provide any additional information below.

IE9 dom Element does not support selectSingleNode neither xpath.
So, if you creating an xml document using IE9 DOMParser or 
document.implementation.createDocument.

On IE9, goog.dom.xml.createDocument uses document.implementation.createDocument 
to create an xml document. It should use goog.dom.xml.createMsXmlDocument_ 
instead (method used by IE6, IE7 and IE8).

On IE9, goog.dom.xml.loadXml uses DOMParser to load xml and create an xml 
document. It should use goog.dom.xml.createMsXmlDocument_ instead (method used 
by IE6, IE7 and IE8).

Attachment is a patch containing a fix. Please apply it from trunk root using :
patch -p0 -i goog.dom.xml.patch

Sorry for incomplete sentence :
So, if you create an xml document using IE9 DOMParser or 
document.implementation.createDocument, you can't select nodes using 
goog.dom.xml.selectSingleNode or goog.dom.xml.selectNodes.

Problem is, on IE9, goog.dom.xml.createDocument uses 
document.implementation.createDocument, and goog.dom.xml.loadXml uses DOMParser.

IE9's XMLSerializer can't serialize MSXML2.DOMDocument object.
So, goog.dom.xml.serialize should use xml.xml instead (already used by IE6, IE7 
and IE8).

A new patch as attachment...
