MSXML3 doesn't have an evaluate() function, but if you're just after
resolving paths (as opposed to evaluating or expressions, for example)
then you can write a JScript script that will do it for you.

This is one that Andrew Kimball posted in January:

  <msxsl:script implements-prefix="some-prefix" language="jscript">
  <![CDATA[
     function selectNodes(nsetCtxt, strExpr)
        {
           // Evaluating strExpr must result in a node-set
           // (unfortunately there is currently no evalExpr method on the MSDOM)
           return nsetCtxt.nextNode().selectNodes(strExpr);
        }
  ]]>
  </msxsl:script>

You call it by passing a node to be used as the context for resolving
the path (usually the context node) and the string that you want to
evaluate.

I hope that helps,

Jeni
