    Hi all,

    I try to create a Perl regexp search to allocate the spots in files that contain a line with the string

    Code: Select all

    ".ObjekteListe().Rows"
    that is NOT followed by

    Code: Select all

    "obj.ObjektFuerBesicherung"
    anywhere in the next 10 lines.

    Can this be done with one regexp? Or do I need to write a fat macro?

    Thanks for any tips.

      Let's try

      Code: Select all

      "\.ObjekteListe\(\)\.Rows".*\r\n(?!(?:(?:(?!"obj\.ObjektFuerBesicherung").)*$\r\n){10})
      No time right now for an explanation, will follow up if the regex works as desired :)

      Cheers,
      Tim

        Hi Tim !

        I tried it out but it did not find anything. So I reduced the problem a bit and cut out the " that I THINK are wrong and came to something like this:

        Code: Select all

        AAAAA.*\r\n(?!(?:(?:(?!XXXXX).)*$\r\n){10})
        I tried with these test lines and found both AAAAA lines instead of only the first occurrence in line 2:

        Code: Select all

          hkjh lskd hkghjjgjlks lhdhd 
        dfdg  AAAAA fdg d  FIND THIS LINE BECAUSE NO 5-X NEAR
        blibla

        We are near ...

          Ah, you're right. There was a "double negation" that screwed it up. How about

          Code: Select all

          AAAAA.*\r\n(?=(?:^(?:(?!XXXXX).)*$\r\n){10})
          This has one drawback: If there are less than 10 lines after AAAAA until end of file, it won't match even if there's no XXXXX in those lines.

            End of file drawback won't really mind.
            But still this one finds both AAAAA ...

              Jul 23, 2009#6

              STOP !!!

              I just figured out that I used the wrong hard disc having 14.20 on it.
              It works well with 15.10.0.1017 which I normally work on.

              Thanks Tim!

                The funny thing is that I think I found a bug in RegexBuddy with this regex. It highlights the second AAAAA although it shouldn't, and when I debug the regex, the debugger reports a failed match attempt. Will have to dig further into this... (and maybe find out a more elegant solution)?

                  There actually was a bug in RegexBuddy which is now fixed. So thanks again for providing us with that interesting problem :)

                    Hi everybody,

                    I don't know what I do wrong, but I need the opposite of what I needed some years ago. Find text AAAAA only when in the next 10 lines is a BBBBB.
                    I could paste the examples I tried, but it could lead you in the wrong direction. So I ask without my examples.

                    Code: Select all

                    lala
                    xyz AAAAA abc
                    bla
                    blubb
                    this is BBBBB so the AAAAA above should be found
                    ....
                    yxx AAAAA cmvnc
                    line 1
                    line 2
                    line 3
                    line 4
                    line 5
                    line 6
                    line 7
                    line 8
                    line 9
                    line 10
                    line 11
                    line 12
                    this is again BBBBB but AAAAA above shall no more be found
                    Any help appreciated.

                      Hi Bego,

                      this should work:

                      Code: Select all

                      \bAAAAA\b(?=(?:.*$(?!(?:\r\n(?:(?!\bBBBBB\b).)*+){11})(?=(?:\r\n.*){11}))|(?:.*$(?!(?:\r\n.*){11})(?=(?s:.*)\bBBBBB\b)))
                      BR, Fleggy

                      EDIT 1: Here is the "opposite" pattern - AAAAA followed by 10 lines not containing BBBBB (or less if there is less than 10 lines after AAAAA) - in another word your original problem

                      Code: Select all

                      \bAAAAA\b(?=(?:.*$(?=(?:\r\n(?:(?!\bBBBBB\b).)*+){11}))|(?:.*$(?!(?:\r\n.*){11})(?!(?s:.*)\bBBBBB\b)))
                      EDIT 2: Some polishing and fixing the near EOF situations.
