How to delete a complete tag with specific content



  • Thanks Claudia,

    but if I use this one, tags are marked with Active Code 0000000001 also.

    How can I avoid that?

    Best wishes
    Chris

    With the info provided it seems that it is working.

    Not sure what I’m missing.

  • Unfortunately, Claudia’s regex can grab too much sometimes. For example, if run on the following data, it will select the first 3 lines with the first Find Next press (good!), but the second Find Next press will match the 6 lines after that (BAD! as that contains a non-zero “Active” field and a replace with “nothing” operation would delete that!):

    <Report>
        <Active>0000000000</Active>
    </Report>
    <Report>
        <Active>0000000001</Active>
    </Report>
    <Report>
        <Active>0000000000</Active>
    </Report>
    

    Try this instead:

    Pre-step: Back up your data!
    Find what zone: (?s-i)<Report>.*?<Active>(?:(0000000000)|(\d+))</Active>.*?</Report>\R
    Replace with zone: (?1:$0\r\n
    Search mode: Regular expression
    Wrap around checkbox: Ticked
    Action: Press the Replace All button



  • Still the same.

  • @Christoph-Kahle

    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



  • @Christoph-Kahle , @Scott-Sumner

    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 said:

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

    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>
