    Hello all,

    I have delved into the UltraEdit help files and this forum trying to find a solution to my problem. I have a log that documents the x, y, and z coordinates of an event. The event is run 12 consecutive times. 11 entries in the log contain pre-planned (theoretical/ideal) coordinates and a 12th entry contains the actual coordinates where all 12 events occurred. I need to replace (delete) the 11 theoretical event entries. I saw in a similar thread Removing lines with partial duplicate content with spaces.

    a solution for doing this but I don't understand how to employ the regular expressions (I'm not a programmer) in my application. I am using UEStudio version 6.20A+2. Below is a sample of an event log I am working on:

    Code: Select all

    Line               Point       X Value     Y Value       Z Value     JD&Time

    From the example above you can see the line, point, x, y, and z values are the same for 11 of the 12 recorded events and the 12th contains the actual positioning. The Julian Date and time stamp increments and is not identical.

    Can someone please help me with the regular expressions to search and replace these duplicate entries.

    Best regards,

      Hi,

      can you try if this Perl regex works for you? (If you haven't done so yet, activate Perl regular expressions in the options dialog first)

      Search string:

      Code: Select all

      (?:(?:^((?:[^\s]+ +){5})).*?\r\n){11}(\1.*?)$
      Replace string

      Code: Select all

      \2
      It assumes that there is the same number of spaces at each location in a 12-line block. If that's not the case, I'd run a replace multiple spaces by one space first, regex for that would be

      Code: Select all

       {2,}
      (note the leading space), replace with " ".

      One caveat: If you don't always have 12 consecutive lines that belong together, the regex might mismatch. If that may be the case, the regex will need to be changed.

      Best regards,
      Tim

        Tim,

        thanks for the input. The Perl regular expression as posted worked.

        Best regards,

        William
