Yes, this functionality is provided through the WSH COM Object VBScript.RegExp; you'd create a pattern to strip words, and use the Execute method to return a Matches collection; this contains a set of Match objects which list the starting position of the word, the value of the word node, and it's length. See any of the WSH resources in my sig block for more details.
