Hello, @w-den-boer, @ekopalypse, @terry-r and All,
As @Terry-r said, any block of lines, below, after the first one, must be replaced with a single empty line
<div class="element">
<div class="learning-text__title--h1">Groene chemie</div>
<div class="learning-text__title--h2">xxxxxxxxxxxxxxxxx</div>
<div class="learning-text__title--h3">
</div>
So, I elaborated a method, which :
Backup your file
Change this multi-lines block in one single line, in your file
Add a numbering at beginning of all lines of your file
Bookmark all the new “single lines” of your file
Paste these lines in a new temporary file
Delete each first line of an identical lines block, in the temporary file
Append the remaining lines of the temporary file in your file
Delete all lines of your file which is repeated in the appended part
Restore the initial appearance of the file ( Rewrite the missing line_break characters and delete the leading digits and the appended lines, at end of file )
In all the explanations, below, relative to search/ replace or mark operations :
The search mode is always supposed to be the Regular expression mode
The Match case option is always ticked
The Wrap around option is always UNTICKED ( IMPORTANT )
We’ll need a temporary character to replace some line-break characters. I decided to use the @ char, absent from your file. Of course, any other character ( ¤, #, ~ … ), not present in your file, can be suitable
I assume that your file is given the name Text_Book.txt
So, first, backup this file as Text_Book.bak ( IMPORTANT )
Open your file Text_Book.txt
Move the caret to the beginning of the first line <div class="element"> of your file ( IMPORTANT )
Perform this first S/R ( Ctrl + H ) :
SEARCH (?-s)(^\h*<div class="element">|\G.+)\K\R(?!^\h*<div class="source source--12">)
REPLACE @
Click on the Replace All button ( 40 occurrences were replaced )
Replace the caret to the beginning of the first line of your file ( Ctrl + Home )
Select the Edit > Column Editor... menu option ( Alt + C )
Select the Number to Insert option
Type in 1 in all the zones
Tick the Leading zeros option
Tick the Dec button, if necessary
Click on the OK button
Move the caret to the beginning of the first line of your file ( Ctrl + Home )
Select the Search > Mark... menu option ( Ctrl + M )
SEARCH @
Tick the Bookmark line option
Click on the Mark All button ( 40 matches )
Select the Search > Bookmark > Copy Bookmark Lines menu option
Open a new file ( Ctrl + N ) I suppose that its name is new 1
Paste all the bookmarked lines in the new 1 file ( Ctrl + V )
Move the caret to the beginning of the first line of this temporary file ( Ctrl + Home )
Perform this second S/R ( Ctrl + H ), in the new 1 file :
SEARCH (?-s)^\d+(.+\R)((\d+\1)+)
REPLACE \2
Click on the Replace All button ( 2 occurrences were replaced )
Select all the remaining contents of the new 1 file ( Ctrl + A ))
Copy these contents in the clipboard ( Ctrl + C )
Select, again, the Text_Book.txt N++ tab
Go to the end of your file ( Ctrl + End )
Type in a new line containing, at least, three = signs and ended with a line-break
Paste the contents of the clipboard under the ===.... line ( so, the new 1 contents )
=> You should get the following Text_Book.txt contents :

Move the caret to the beginning of the first line of Text_Book.txt file ( Ctrl + Home )
Perform this third S/R ( Ctrl + H ), in the Text_Book.txt file :
SEARCH (?s)^((^\d+)(?-s).+\R)(?=.+^===.+^\1)
REPLACE \2\r\n
Click on the Replace All button ( 6 occurrences were replaced )
Move, again, the caret to the beginning of Text_Book.txt`** file, if necessary
Finally, perform this fourth S/R ( Ctrl + H ), which restores the initial appearance of the file :
SEARCH ^\d+|(@)|^===(?s).+
REPLACE ?1\r\n
Click on the Replace All button ( 94 occurrences were replaced )
If we compare with the expected results, given in this post :
https://community.notepad-plus-plus.org/post/57758
We do get identical files , if we except the final line-break ;-)) Nice, isn’t it ?
If necessary, I could give you, next time, some hints on the regexes involved in the process !
Best Regards
