Jeff-
thanks for the reply. i can deal with context in a different method,
in your solution, i still grab "<a>" and "test." and "&wow*&&" as
keywords. i want to send this method a string, and get an array of
letter-only words returned. if you have context ideas, i'd love to
hear those too, but the first step is just harvesting only character
words from strings.
thanks,
dino
