          I’m certainly willing to assist, but I have no clue what “send me the first request to check and I’ll tell you what results I want omitted” means. (Which to me is the long form of my earlier response of “???”.)

            thanks a lot,

            I was talking about the original, first message,
            ignore the follow-up for now,
            we’ll talk about them after the initial results

              Hello, @patrickdrd, @scott-sumner and All

              Scott, I suppose that @patrickdrd was expecting your first regex attempt, in order to test it on real data ! However, I must admit that the @patrickdrd’s formulation looks like more as an imperative order than a polite request for some regex help :-(


              Anyway, @patrickdrd, I’ll try to give you some hints !

              Here is, below, the general form of the regex S/R which deletes all lines containing, exactly, n times the Char character ;-))

              SEARCH ^(?:([^Char\r\n]*)Char){n}(?1)\R

              REPLACE Leave EMPTY

              In your case, as you, probably, want to delete all lines containing, exactly, 1 hash char, only, whatever its location, the correct regex becomes :

              ^(?:([^#\r\n]*)#){1}(?1)\R

              which can be shortened as :

              ^([^#\r\n]*)#(?1)\R

              Notes :

              • The [^#\r\n]* part represents the longest range, even null, of characters different from # and line-breaks, stored as group 1 and re-used, after the # symbol, in the (?1) sub-routine call syntax, which is equivalent to [^#\r\n]*

              • As usual, the \R form matches any line-break, whatever the file type ( Windows, Unix or Mac )

              Cheers,

              guy038

                  ok, I’ve just tested guy038’s suggestion and it’s not “safe” because
                  it matches these lines I would like excluded:

                  so maybe my best shot is #\s

                    the (?1) sub-routine call syntax

                    Gotta love the sub-routine syntax…why write something like [abc]{5} when you can write (?+1)(?'name'[abc])(?1)(?-1)(?&name) ? :-D

                    Example shamelessly stolen from here after I read up on it…and OK, that example includes named groups as well…but all good stuff (that works in N++).

                      Hey, you’ve been around long enough to know to indent every line of example text with 4 spaces before posting. :-)

                      (Noticed that you escaped some * but apparently not all because some of your text is in italics…way easier to just indent 4 and forgetaboutit)

                        Hi, @patrickdrd, @scott-sumner and All

                        Scott, your regex use of the (?1) syntax made me laugh a lot ;-)) Of course, it would be ridiculous to use such a regex !

                        So, the generic regex S/R, of my previous post, which deletes all lines containing, exactly, n times the Char character can, also, be written :

                        SEARCH ^(?:[^Char\r\n]*Char){n}[^Char\r\n]*\R?

                        REPLACE Leave EMPTY


                        Now, generally speaking, when you want to delete some lines of a file, based on a criteria, just determine :

                        • The common characteristics of all the lines which have to be to kept

                        OR the opposite :

                        • The common characteristics of all the lines which have to be deleted

                        patrickdrd, reading more carefully, and from your last example, it’s seemed that you would like to delete, either :

                        • All lines, containing the #$ string

                        • All lines, containing more than one hash character #

                        In that case, use the regex S/R, below :

                        SEARCH ^.*#(.*#|\$).*\R?

                        REPLACE Leave EMPTY

                        Cheers,

                        guy038
