MSMXL 3 supports XPath so you need to set
   xmlDoc.setProperty "SelectionLanguage", "XPath"
after the loadXML call, then you can use the methods xmlDoc.selectNodes 
and xmlDoc.selectSingleNode to find nodes using XPath expressions.
XPath docs are here:
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/6da1b6e3-256e-4919-8848-53b425f72ed1.asp>

A short XPath tutorial is here:
<http://www.w3schools.com/xpath/default.asp>

If you need help formulating an XPath expression then show a short but 
relevant snippet of the XML.
