How to preserve and access processing instructions in MSXML IXMLDOMDocument2

Question

I have this problem, that I need to access processing instruction in MSXML IXMLDOMDocument2 interface.
Is it possible to do XMLDocument.load() and have access to xml-stylesheet instruction?
If it is, how to do it right?

I have xml with:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="transform.xsl"?>
...

and I need to extract xml-stylesheet href value.
But XMLDocument seems to not contain this processing instruction after XMLDocument.load() operation.
So than I can't perform:

XMLDocument.transformNode(XSLDocument);

with XSLDocument being filled with what is inside transform.xsl, because I don't know where transform.xsl is being located.

Thanks for any help.

Assuming MSXML doesn't model the XML declaration as a node (I don't think it does but I am not sure) you should be able to access the processing instruction as XMLDocument.firstChild and XMLDocument.firstChild.data gives you then the "value" of the processing instruction, i.e. the complete string type="text/xsl" href="transform.xsl".

You should also be able to select the node using XPath and XMLDocument.selectSingleNode("processing-instruction('xml-stylesheet')").data, only XPath is not the default selection language in MSXML 3 (only in MSXML 6) so for MSXML 3 you would need to first set XMLDocument.setProperty("SelectionLanguage", "XPath").
