Copy, search and replace between 2 HTML files

Hi @guy038 and all,

Definitely, it works perfectly with @guy038 smart solution. Many many many thanks for your solution which helps me a lots to save my time. It would be really nice if you can explain the regexes syntax, when you have free time!

In addition, I want to split file A into 895 files based on “KOSMOS”. Could you please give me a further favor? For instances,

file 1: From the very beginning of file A to the first KOSMOS, but not include it.
file 2: From the 1st KOSMOS to the 2nd KOSMOS (not include the 2nd)
file 3 ,… file 895 are similar file 2. The last KOSMOS (895th) I will be excluded.

Bests,
Kosmos

Hello, @hientwi, @astrosofista and All,

I’m quite confused, because I don’t see, exactly, the connexion between your previous goal and your new one ?

Indeed, once your file A has been modified with our previous process, it does not contain any KOSMOS line which have all been replaced with a specific line from file B. So, it would be more difficult to determine each section which would have to be saved in the 895 files !

On the other hand, If you decide to split the initial contents of file A into 895 files, first, then you’ll have to replace the first KOSMOS line of each file by the appropriate line of file B which seems to be more difficult than with my previous method !

Please, could you enlighten us ?

Best Regards,

Hi @guy038 and all,

Sorry that I made you and others confused. I have another purpose which is totally different from my previous question. It means that I have two copies of file A. The one I wanted to split into multiple files based on “KOSMOS”. The other is used for my previous question. They are totally different questions.

Best regards,

Hello, @hientwi, @astrosofista and All,

Sorry to be late ! So OK : these are two tasks absolutely different !

Well, as you would like to manage file’s creation, regexes are not a nice tool for such a task. Personally, I would use the Gawk application. So, if you do not have this program, yet :

Create a new folder
Download the gawk-5.0.1-w32-bin-zip archive from https://sourceforge.net/projects/ezwinports/files/
Double-click on the gawk-5.0.1-w32-bin-zip archive
Double-click on the bin folder
Extract only the 5 files gawk.exe, libgmp-10.dll, libmpfr-4.dll, libncurses5.dll and libreadline6.dll in the new folder
Copy your file A in that folder, which will be renamed as File_A.txt
With N++, just add a line KOSMOS, at the very beginning of File_A.txt
Open a DOS cmd window
Type in and run the following command :
- gawk "BEGIN {n=0} $0!=\"KOSMOS\" {print > \"File_\"n\".txt\"} $0==\"KOSMOS\" {n++}" File_A.txt
Wait a few moments … …

Et voilà ! You should see, in this new folder, 895 files from File_1.txt to File_895.txt ;-))

An other possibility would be :

With N++, just add a line KOSMOS, at the very beginning of File_A.txt
Change, in your File_A.txt, each KOSMOS line into a pure empty line, with the regex :
- SEARCH (?-i)^KOSMOS(?=\R)
- REPLACE Leave EMPTY
Then, in your DOS window, you would run the following command :
- gawk "BEGIN {n=0} NF {print > \"File_\"n\".txt\"} !NF {n++}" File_A.txt

That’s all ! Powerful, isn’t ?

Remark : I suppose that your file did not contain, initially, any true empty line !! ( may be searched with the regex ^\R )

For more information, you can download the latest PDF manual ( gawk v5.0 ) from https://www.gnu.org/software/gawk/manual/

Best Regards

P.S. :

In order to select each zone, beginning with a KOSMOS line, till the next KOSMOS line, excluded, of your File_A.txt, simply use the regex :

SEARCH (?-i)(KOSMOS)?(?s).+?(?=^KOSMOS\R|\z)

Dear @guy038 and all,

Dear @guy038, dear all

Today, I have tried your first solution (File_B.txt which contains KOSMOS) and I got the error as in the following:

It is the same with your second solution with File_A.txt with blank line) as well.

Could you please kindly give me a favor?

Many thanks in advance!

Dear @guy038 ,

I got the solution by correct quotations as the followings:

gawk ‘BEGIN {n=0} NF {print > "File_"n".txt"} !NF {n++}’ File_A.txt

Best regards,
Kosmos.
