I think you misunderstood. The new Extractor in the latest CVS is not a function at
all. It's a new gui element that gives you the same capabilities as the
__regexFunction. Look for it in the right-click menu under your sampler.
Your example below seems impossible, so I don't know what to say. I don't see
how your second regex could have possibly worked.
