Find text x followed by text y up to 10 lines later

Bego · Jul 23, 2009#12009-07-23T07:26+00:00

Hi all,

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

".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
blubb sdflökjsdaf iobjekt 
blubb besicherung
sdkfj sdlkjaflöksja öskfdj sk
blibla
blubb sdflökjsdaf iobjekt 
blubb besicherung
sdkfj sdlkjaflöksja öskfdj sk
blibla
blubb sdflökjsdaf iobjekt 
blubb besicherung
sdkfj sdlkjaflöksja öskfdj sk
blibla
blubb sdflökjsdaf iobjekt 
blubb besicherung
sdkfj sdlkjaflöksja öskfdj sk
   dfdg  AAAAA fdg d  DO NOT FIND THIS LINE, 5 - x is near
blibla
blubb sdflökjsdaf iobjekt 
blubb besicherung
sdkfj sdlkjaflöksja öskfdj sk
g klfsdglskh XXXXX d gh jh
blibla
blubb sdflökjsdaf iobjekt

We are near ...

Best regards, Bego

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.

Bego · Jul 23, 2009#52009-07-23T19:38+00:00

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

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.

Oh yes.

Thanks man!
