Probably you haven't set the "SelectionLanguage" property of the DOM
Document as "XPath" rather than "XSLPattern" or whatever it is that
MSXML uses as the default. The "XSLPattern" language doesn't support
as much as XPath and, of course, isn't standard.

Assuming that history[curDim].oDoc returns a DOM Document object, use
something like:

  history[curDim].oDoc.setProperty("SelectionLanguage", "XPath");
  history[curDim].oDoc.selectNodes("//Message[position() = 1]");

BTW, you can use just [1] instead of [position() = 1] if you like --
it means exactly the same thing.

Cheers,

Jeni
