in thread regex needed with match operator

Thanks broquaint,
Would you mind explaining exactly what the \z and x are doing in the regex?

Thanks again

    Sure, to quote the docs
    \z Match only at end of string
    This is very similar to $ except $ matches the end of a line or before a newline.
    x Extend your pattern's legibility by permitting whitespace and comments.
    As it says, it allows for more readable regex, which is generally desirable considering the acute succinctness of regular expressions.

      Thank you,
      It makes a lot more sense now, and I didn't realize the differnece between $, and \z, but now I do.
