If you have MSXML v4 then use the language filter to only include VB, then search again.
Of course you need to use the SDK which comes with the XML parser. You should be able to download it from Micro$oft's site.
Of course I don't know what you want to do, but usually you should create an MSXML2.DOMDocument (which will represent your XML doc), read the XML file (with the load method), and set your doc's documentElement property (which is an IXMLDOMElement). From this point on you should be able to navigate through the XML tree structure.
Don't be frightened by the tons of properties and methods I was really scared the first time I saw them. You'll get familiar with them soon enough.
Good luck!
