How to bookmark lines around a line containing a specific expression 'XXX' ?

mkupper

@sam-rathod As @PeterJones noted, your regular expression is valid.

@all - I discovered it’s challenging as I think I think @sam-rathod intended to start the extraction at the line that starts with SACS CONNECT Edition and that the does not count empty or blank-only lines as “lines.”

But, how can can we go backwards by nine lines that are not blank/empty from the IGNORED anchor?

Thinking forwards is much easier for me: ^SACS CONNECT Edition(?s).*IGNORED(?-s).*

@sam-rathod the (?s) part puts the regular expression engine in a mode where dot also matched end of lines meaning we will skip/match all lines from SACS CONNECT Edition up to the word IGNORED. Once we get to IGNORED we do (?-s) which turns the dot matching end-of-line thing off and the final .* picks up the remainder of the line.

To make this safer I would use the case-sensitive (?-i)^SACS CONNECT Edition(?s).*IGNORED(?-s).*

Hey
The output that I am expecting:

The area marked in grey is what i want MARKED

This is the error that it is showing after entering the regex command:

I tried attaching files but i am unable to.

Thanks guys for reaching out so quick to such an old topic, much appreciated.

Hello,

Actually the occurrence of SACS CONNECT Edition is at multiple times so i guess that might be one issue, also i tried the <(?-i)^SACS CONNECT Edition(?s).IGNORED(?-s).> but it is giving this error:

@sam-rathod - I start out by trying to see if there is a pattern to the data that I can take advantage of. I test this carefully to understand any possible exceptions to the pattern.

You have provided two examples and so from that the pattern I see is the the sections that you want to highlight start with these lines:

                                      ** SACS COLLAPSE IMPACT ENERGY ABSORPTION **
          **** FINAL DEFLECTIONS AND ROTATIONS FOR LOAD SEQUENCE LCE1 ****

I also see that above this is the page header which starts with SACS CONNECT Edition and so first do a test (?-i)^SACS CONNECT Edition and count how many page headers there are. Let’s say there are 957 in the file. I write down 957 so I won’t forget.

I then build a regular expression that matches the start of the data. I’ll do (?-i)^ +\*+ [A-Z0-9 ]+ \*+$ and verify that it matches exactly 957 times in the file. If it fails to match exactly 957 times then I tighten or loosen the regular expression as needed until it nails 957.

I do the same thing for the IGNORED lines. I first do (?-i)IGNORED$ and count. Let’s say there are 57 and so I write that down. The full pattern for the IGNORED lines seems to be (?-i)^ +\*{4} WARNING - THE REMAINING +[0-9]+ INCREMENT$S$ OF THE LOAD STEP WILL BE IGNORED$ Adjust that expression until it gets exactly 57 matches.

Now we know we have 957 page headers and 57 of them are the ones we are interested in. As the sample size you have provided only has one example of what we want to match I will use a more general

(?-i)^(?: +\*+ [A-Z][A-Z0-9 ]+ \*+\R)(?:.*\R){1,25}(?: +\*{4} WARNING - THE REMAINING +[0-9]+ INCREMENT\(S\) OF THE LOAD STEP WILL BE IGNORED)$

Drop that into Notepad++. I added a couple of extra parentheses in there so that when you move the cursor to a ( or ) that Notepad++ will highlight the other one of of the ( … ) pairs.

The groups within that rather long expression are:

(?-i) - Turn the ignore letter case flag off.
^(?: +\*+ [A-Z][A-Z0-9 ]+ \*+\R) - This is the thing that matches the start of the blocks we want to select. We know it matches 957 times.
(?:.*\R){1,25} - Allow for one to 25 lines that may be empty or may have stuff.
(?: +\*{4} WARNING - THE REMAINING +[0-9]+ INCREMENT$S$ OF THE LOAD STEP WILL BE IGNORED)$ - This matches the last line of the things we are interested in.

In this case I solved the problem by using (?:.*\R){1,25}. I know that the first line will match many times but don’t want to bother with scanning too far before testing for the last line. With a better sample size I likely would tune {1,25} to be a better match for how far down that IGNORED line is.

This is the error that it is showing after entering the regex command:

That’s an exeedingly fuzzy screenshot.

But to me, that looks a lot more like (.*\R}{10}^.*ignored.*\R instead of (.*\R){10}^.*ignored.*\R – the first group is accidentally closed by a curly-brace } instead of a close-parenthesis ). Assuming that fuzzy character really is }, I can replicate your error; and if I hover over the ... in the error message, it tells me exactly what’s gone wrong with the expression:

If it’s actually something else wrong with yours, that ... hover will help you diagnose it.

But either way, if I enter the regex that you claimed to use, rather than the one that your fuzzy screenshot shows, it just shows that it’s not finding text, not that there was an error in the regex.

I tried attaching files but i am unable to.

That’s not the right way of sharing data, as has been explained in the FAQs about formatting example text and the template for search/replace questions. Those FAQs show how to format your text so that it appears in the copyable text box (which is how I changed your original post using moderator powers to show the data in the text box – I will actually go back and remove the extra line endings, which may have been accidentally introduced when I did the first edit).

When i use the expression that you said you were using, on the data that you had in your post, I match almost what your followon post said you wanted to match:

The reason it doesn’t match everything is because you said you wanted 10 lines before the “ignored” line… but your screenshot with manual highlight shows that you actually wanted 12 lines before the “ignored” line, so you just need to change the count from {10} to {12} …

And, as your regex uses ignored but your actual text is IGNORED, and as we want to make sure that the . from the first capture group doesn’t match newlines, the final regex you should use is
FIND WHAT = (?i-s)(.*\R){12}^.*ignored.*\R – as shown below, this matches what you say you want to match.

This did the wonder, thanks for the help man on my own i would never been able to figure this out. I am new to notepad++ will appreciate if you can share some learning material to start from basics.

Thanks a Lot.

@PeterJones said in How to bookmark lines around a line containing a specific expression 'XXX' ?:

(?i-s)(.*\R){12}^.ignored.\R

The screenshot looks fuzzy but i had entered the same equation that was been mentioned by @guy038.

Will go through the FAQs for sharing data and will understand how to post on this.

I tried the final Regex :

(?i-s)(.*\R){12}^.*ignored.*\R

Thanks for actively resolving the issue i was facing, will appreciate if u can share some learning material to start from the basics.

Thanks & Regards,

Hello, @sam-rathod, @peterjones, @mkupper, @alan-kilborn and All,

I suppose that dealing with files with important size may lead to this regex message, even if this regex does work properly with small files :-((

So, @sam-rathod, could you try with this new regex version :

SEARCH/MARK (?-is)^(?:.*\R){12}.*IGNORED.*\R

Hello,

If i have range of text for example

"This is the specific text in the document that i will search"
Line1 that dont want marked
Line2 that dont want marked

Line3 that dont want marked

Line 1 want to mark
Line 2 want to mark
Line 3 want to mark
Line 4 want to mark
Line 5 want to mark

""This is the specific text in the document that i will search"
Line1 that dont want marked
Line2 that dont want marked

Line3 that dont want marked

Line 6 want to mark
Line 7 want to mark
Line 8 want to mark
Line 9 want to mark
Line 10 want to mark

The output i am expecting

Line 1 want to mark
Line 2 want to mark
Line 3 want to mark
Line 4 want to mark
Line 5 want to mark
Line 6 want to mark
Line 7 want to mark
Line 8 want to mark
Line 9 want to mark
Line 10 want to mark

^.*This is the specific text in the document that i will search.*\R(?:.*\R){5}((?:.*\R){5})

Tried various option but unable to skip the lines as everything after specific text is getting marked.

Hi, @sam-rathod and All,

I do not understand clearly what you want to achiveve !

Given this INPUT text, below :

"This is the specific text in the document that i will search"
Line1 that dont want marked
Line2 that dont want marked

Line3 that dont want marked

Line 1 want to mark
Line 2 want to mark
Line 3 want to mark
Line 4 want to mark
Line 5 want to mark

""This is the specific text in the document that i will search"
Line1 that dont want marked
Line2 that dont want marked

Line3 that dont want marked

Line 6 want to mark
Line 7 want to mark
Line 8 want to mark
Line 9 want to mark
Line 10 want to mark

And let’s suppose that you’ve previously bookmarked all the lines with the Line #..# want to mark syntax

Then just use the Search > Bookmark > Remove Unmarked lines option and you’re left with the following expected OUTPUT text :

Line 1 want to mark
Line 2 want to mark
Line 3 want to mark
Line 4 want to mark
Line 5 want to mark
Line 6 want to mark
Line 7 want to mark
Line 8 want to mark
Line 9 want to mark
Line 10 want to mark

No i am not able to bookmark only the specific line that i want mark.

Basically i want to find a specific text , ignore 4 lines after it and mark& select 5 line after the specific text & 4 lines.

@sam-rathod

Sample of data i am trying to figure out.

Hello, @sam-rathod and All,

Ah, OK. Now, I understand all the story !

Just note that you should have put your text as raw text, using the </> indication when replying and not pasting an image. Indeed, even with a OCR plugin, within my favorite graphic viewer, I was not able to convert the letters of your image into raw text :-(( This explains the delay of my reply !

So, with this kind of INPUT text :


 SACS CONNECT Edition V(15.1) - CL                                                        Company: .
             *********** SACS IX SEASTATE PROGRAM ***********               DATE 23-OCT-2024  TIME 07:31:44   SEA PAGE   208
                                     ***** SEASTATE COMBINED LOAD CASE SUMMARY *****
                                              RELATIVE TO MUDLINE ELEVATION
   LOAD  LOAD              FX           FY           FZ           MX           MY           MZ
   CASE  LABEL
                          (KN)         (KN)         (KN)       (KN-M)       (KN-M)       (KN-M)
                         
   127  7119             -125.62      -190.83     -4342.63       4582.3      -3032.8      -1382.1
   128  7120                0.54      -212.18     -4388.18       5164.0        863.9      -1432.1
   129  7121              111.01      -159.93     -4333.70       3602.5       4267.7      -1399.5
   130  7122              202.80       -78.61     -4340.74       1053.9       7076.4      -1374.5
   131  7131              264.55       -39.54     -4341.04       1111.7       8733.7      -1299.3

Just use the search regex, below, in order to mark the expected lines :

SEARCH / MARK (?-is)^.+SEASTATE COMBINED LOAD CASE SUMMARY.+\R(?:.+\R){5}\K(?:.+\R){5}

Notes :

Note that I use non-capturing groups (?:.......), instead of capturings ones (.......), for each block of five lines.
Now, after the complete line containing the string SEASTATE COMBINED LOAD CASE SUMMARY, with this exact case
And the five lines that follow,
The \K syntax cancel any previous search, so far
So, the next five lines are only taken in account by the regex engine and marked

Method :

Open the Mark dialog ( Ctrl + M )
Uncheck all box options
SEARCH / MARK (?-is)^.+SEASTATE COMBINED LOAD CASE SUMMARY.+\R(?:.+\R){5}\K(?:.+\R){5}
Just check the Bookmark line, Purge for each search and Wrap around box options
Select the Regular expression search mode
Click on the Mark All button
Now, you may either :
- Copy all these bookmarked lines in an other new tab with the Search > Bookmark > Copy Bookmarked Lines option
- Click on the Copy Marked Text button and paste the clipboard contents in an other tab
