    Regex question

    Sorry if this is a repost. According to Outlook Express, I posted this
    yesterday but it's not showing for me and I can't find it on Google Groups,
    so I'm assuming it didn't go through for some reason. If it did and this is
    a dupe, I apologize....

    I have a regex question and it never occurred to me to ask here, until I saw
    Jesse Houwing's quick response to Phil for his Regex question.

    I have some filenames that I'm trying to parse out of URLs.

    (href=("|')http ://.www\.thesite\. com/.{1,7}/)(?<filename>.[^"|'])

    This generally works, but the problem is some of the image files have
    ..th.jpg at the end to indicate thumbnails. I want to exclude those. I just
    want the ones that don't have .th. before the file extension.

    I've tried using forward and reverse negative lookups, but I guess I'm not
    using them correctly. Any help on how to get a non-match for a .th. would be
    great.

      Oops

      Okay, I see what happened here. Outlook express grouped my question with
      another of the same topic, for some reason.. Sorry about the repost.
