In IE9, how to reference XML document from JS after XSL processing instruction runs

Hello,

Below is a modified version of the example here: msdn.microsoft.com/en-us/library/ms757058(v=vs.85).aspx.
It demonstrates functionality that is very similar to a legacy site I am currently supporting.

The difference is that in my example, I am not using data islands. Instead I am using a Processing Instructions to transform the initial xml document and then I am attempting to use Javascript to transform the document again after the initial render.

The problem is that in IE9 Standards mode there doesn't appear to be any access to the initial xml or xsl document from Javascript, after the content has been transformed to HTML.

This example will however work in Compatibility View where I can still access document.XMLDocument and document.XSLDocument.

Q1. In IE9 Standards Mode, is there any way to access the XML/XSL documents that produce a HTML page after it is rendered?

Q2. Can anyone confirm that support for document.XMLDocument and document.XSLDocument went away with support for XML Data Islands in IE9?

Thanks in advance
