      @Terry-R Sir, Thanks. Worked Nicely Only thing its little lengthy process.
      Only one small Bug Found that after completion END tag creates another 4 empty Lines and one More END tag adds

      END



END

      Other than this All is fine. Thanks once again.

          I have another question, what if I have 20 txt files in one folder, and I want to make the replace with another 20 txt files in another folder, and each of files from folder 1 also begin with Start 1 and ends with END and the same in folder 2?

          And consider that the files from both folders has the same names:

          File-1.txt -> File-1.txt
          File-2.txt -> File-2.txt
          File-3.txt -> File-3.txt
          File-4.txt -> File-4.txt
          …
          File-20.txt -> File-20.txt

            @ohm-dios,

            You said :

            Found one Issue when replace, the number sequence looks like this(my file has ex:340 paragraph) 199,299,336,49,59,69,79,89,99,109,119,…199,209 etc Instead of 1,2,3.

            I did a quick test, replacing the values 1, 2, 3 and 4 with 199, 299, 336 and 49, without any problem !?

            So, as usual, could you provide some text to test against and some information on the issue. How can you expect some help without giving us any data and vision of your workflow ?!

            BR

              Hope you will get my point. The sequence or ordering changes instead of 1,2,3. It shows first 13.Thanks.

                Hello, @ohm-dios, @terry-r and All,

                Ah… OK ! I understood the problem :

                • First, I suppose that the last line of your file did not end with two chars CRLF. So the regex just considered the START 13 ..... END paragrah as the last valid one !

                • Secondly, I forgot to limit the same number to find, \1, with a line-break needed right after. Indeed, when searching in the second part ( File_1 part ) for START 1, we must tell the regex to avoid matches as START 11 or START 199 and, generally, START 1 followed with any range of digits !

                So, the following regex S/R should work correctly, even if the last line of current file does not end with CRLF :

                SEARCH (?s-i)START\h*(\d+).+?END\R(?=.+(START\h*\1\R.+?END\R?))|^===.+

                REPLACE \2

                You’ll note the new syntax \1\R to get the exact number, in the part under =========== and the \R? syntax, near the end of the regex, in order to match, whatever the last chars ending current file !

                Best Regards

                guy038

                    @guy038 P.S.: Again sorry to disturb it works upto 100 after that it just replace the whole content from file_1(the one which pasted after ===========).Please look into that.

                      Hi, @Ohm-dios and All,

                      But, my regex SR is just built to do so !!

                      Indeed, the result file File_3.txt contains :

                      • Firstly, the contents of File_2.txt

                      • The line ============

                      • Secondly, the contents of File_1.txt

                      • Then, when running the S/R, it :

                        • Copies all contents of paragraphs, located after the line ========, into the corresponding paragraphs, located above the line ========

                        • Finally, deletes the line ========== and everything, till the very end of file

                      • So, after saving the new contents of File_3.txt, this file becomes your new expected file File_2.txt

                      Or, am I missing something obvious ?

                      BR

                        @guy038 .Functioning is absolutely Right. Only 100 paragraph copied and corresponding file_1 deleted. But after 100 , the file_2 content totally replaced by file_1. Instead of copied and deleted. May be the number issue because until 100 perfect after that only issue comes.
                        I understood the function . lines ====== below will be copied to respective above after it gets deleted till the iteration of Paragraph Numbering.
                        1-100 NO ISSUE. Issue starts from 101 then all the content of file_1 directly replaced till end of file_2.Hope i explained a little you may catch my point.

                          @Ohm-Dios said in Copy From one text file and Paste it on another Text File using Regex:

                          Only one small Bug Found that after completion END tag creates another 4 empty Lines and one More END tag adds

                          If you are finding there are unpaired END tags then I would assume they were there from the start. As a suggestion you can count the number of START and END tags in each file to confirm each file has the same number. To do so, use the Find function. Then type in (?-i)^START\s*\d+$ and click on the Count button. perform the same with (?-i)^END$. After getting that number you could then also perform another count as a secondary verification to count each set of START/END tags by using (?s-i)^START\s*\d+\R.+?^END$. If any of those numbers differed from the others you have an issue with your data.

                          There is one other count I’d like you to do since I have thought of one possibility where the empty START/END line would appear after the replacement START/END line at step 4. Use (?-si)^START.+?\R[!"#$] on file 1 and confirm the number is 0. If it is NOT 0 then I may need to amend slightly my regexes

                          As for my solution being a lengthy process, it is, intentionally. @guy038 solution is a much neater solution, however as he pointed out there can be issues using it on larger amounts of data. That’s why I refrain from offering it.

                          You also posted a question about step 5 with 2 START tags. I don’t know if you completely understand each step, although I did provide a description for each step. In step 5 we have 2 START/END lines together. The first should be the “empty” START/END line, the second the replacement START/END line. As the first has the original “line number” attached at the end we need to keep that. Step 5 regex identifies the relevant strings of characters in both lines, keeps the replacement START/END string, but attaches the number from the first line.

                            Hello, @ohm-dios,

                            If your File_1 and File_2 files are not personal nor confidential, could you send me these files, by e-mail, for further testing sequences ?

                            My e-mail address, temporary displayed :

                              @guy038 Dear sir, Files are not personal. But i found the issue as i told after 100, then i checked START 101 it has START 101 . (FULL STOP) That only caused the issue. After clear the character it worked without any issue. It’s god’s grace that’s why i have got help from like you masters to save my efforts and time . My Love and Hug to You. Thanks You Rock always.

                                Hi, @ohm-dios,

                                Ah…, of course ! In the search regex :

                                (?s-i)START\h*(\d+).+?END\R(?=.+(START\h*\1\R.+?END\R?))|^===.+

                                You’ll notice the part START\h*\1\R, which defines the beginning of the paragraph that need to be copied, located under the ======== line

                                The back-reference \1 to the group 1 ( which is the number after the START string and space char(s) ) must be immediately followed with the EOL chars ( \R )

                                Thus, if anything is located between the number and the end of line, it cannot be equal to the corresponding number, located above the ========= line => NO match of this specific paragraph :-((

                                BR
