        Well, trying my solution on that new data works for me!

          I see my match get’s expanded until a report tag happens with action 000000.
          Scotts version is working for me as well.

          Cheers
          Claudia

            find what:

            (?s)<Report>(?:(?!</Report>).)*<Active>0000000000</Active>.*?</Report>

            replace with empty

            This seems to work as well :-D

            Cheers
            Claudia

              So some explanation is probably in order.

              The Find what will match EVERY <Report> thru </Report> (with line-ending after the closing tag) one-by-one as it moves thru the file. The difference is that when an all-zeroes Active field is encountered, it gets saved into “group #1”.

              The Replace with is where the difference comes in: If “group #1” was matched during the Find, the replacement text is “nothing” (thus a delete operation), otherwise it is the entire match (represented by $0) from the find stage.

              The ?1 is a “test” at replacement time. It’s general form is ?1a:b and means "if group #1 was matched at find time, replace with “a” at replace time, otherwise replace with “b”. In our specific case above “a” is omitted, which means “insert nothing here”.

                Hello, @christoph-kahle, @claudia-frank, @scott-sumner and All,

                Now, most members of N++ community, who use regexes, in search/replacement operations, know the main difference between a lazy and a greedy quantifier ! For instance, given the * quantifier, which is a shortcut of the syntax {0,} :

                • The (?-s)0.*9 regex matches the greatest range of characters, between digits 0 and 9 of a same line

                • The (?-s)0.*?9 regex matches the tallest range of characters, between digits 0 and 9 of a same line

                • The (?s)0.*9 regex matches the greatest range of characters, between digits 0 and 9, even of several lines

                • The (?s)0.*?9 regex matches the tallest range of characters, between digits 0 and 9, even of several lines

                So, assuming the one-line text, below :

                1234567890<Report>First Block</Report>123457890<Report>Second Block</Report>1234567890<Report>Third Block</Report>1234567890

                You should, easily, see the difference between the regex (?-s)<Report>.*</Report> and the regex (?-s)<Report>.*?</Report>

                Just note that the later regex could be rewritten, as well, (?-s)<Report>((?!</Report>).)*</Report> . Indeed, this regex means :

                • Find a zone, beginning with <Report>, ending with </Report> and which does not contain, at any position, after <Report>, till </Report>, the string </Report> !

                Now, why the first form the the Claudia’s regex, below, is not totally correct ?

                (?s)<Report>.*?<Active>0000000000</Active>.*?</Report>

                I, probably, would have build this one, at first sight, too :-) Indeed, this regex looks for the nearest string <Active>0000000000</Active>, after the start tag <Report>, itself followed by the nearest end tag </Report>. Everything seems OK…

                However, we do a mistake because the fact of reaching the nearest <Active>0000000000</Active> and the fact of reaching the nearest </Report> are independent events ! And we may find, first, a <Active>0000000000</Active> block, after crossing many end tags </Reports :-((

                So, in order to tell the regex engine to find, first, the nearest string <Active>0000000000</Active>, of the SAME block <Report>.....<Report>, we must use the second Claudia’s regex, below :

                (?s)<Report>(?:(?!</Report>).)*<Active>0000000000</Active>.*?</Report>

                Notes :

                • No need to change the first * greedy quantifier, before <Active>, in its lazy form ! Actually, due to the negative look-ahead, you already know that the range, between <Report> and <Active>..., is part of the current <Report>...</Report> zone, which always contains, in Christoph’s file, an unique block <Active>.....</Active> !

                • On the contrary, the last *? lazy modifier, before </Report>, is, of course, mandatory, to get the end of the current <Report> tag

                Cheers,

                guy038

                  Hi Guy! I’m sure you can appreciate the humor in your statement. Of course the string </Report> isn’t going to occur before the string </Report> ! Because if it did, then it would have! ;)

                    Hi, @scott-sumner,

                    Yes, my statement looks a bit weird ! But, English is not my mother language, and probably, a better formulation exists, in fluent English-American :-)

                    Oh !, Perhaps, I should had write :

                    • Find a zone, beginning with <Report>, ending with </Report> and which does not contain, at any position, after <Report>, till </Report>, AN OTHER string </Report> ?

                    Actually, I just wanted to point out, that the simple case (?-s)a.*?b, with a lazy quantifier, may, as well, be written, with a greedy quantifier :

                    • (?-s)a((?!b).)*b

                    • a[^b\r\n]*b

                    Cheers,

                    guy038

                      @Scott-Sumner,

                      You’ve got to admit, even for native speakers, it’s sometimes hard to translate a regular expression into clear English. I would probably phrase the non-greedy version as

                      Find a zone, beginning with <Report> and ending with the first instance of </Report>

                      and the greedy version as

                      Find a zone, beginning with <Report> and ending with the last instance of </Report>

                        Thank you. It works for me in a similar case.
