      One more thing please.
      The “Chapter” is actually a book name.
      It is the first word in the file. I need that to be read into a variable and put in the beginning of the line instead of the word “Chapter”

      I am working on it, but if you can help that would be appreciated.

        Well, obviously some examples would be extremely helpful, otherwise I’m just guessing.

        And my first guess would be to have this as the regex:
        (?-s)^\\v (?=(.+\R)+?(.+?\d+$))
        You will see I’ve changed the Chapter<space>\d+ to .+?\d+$. The .+? means to consume characters in a non-greedy fashion and stop when a digit appears. Then the rest says to also consume digits (as many as occurs together) and stop at the end of the line ($). So if there are spaces behind the digits it won’t work. Without examples I can’t be sure.

        Terry

        PS you said first word in the file. So do you really mean it’s the word at the start of each group OR truly ONLY the first line in the file. If ONLY the first line then that is an entirely different sort of regex. Examples with say 2-4 groups of verses. And AGAIN include 2 code boxes, 1st being existing data and 2nd being how you want it to look.

          @Terry-R Thanx.
          I need the first word in this file to be used for all “\v”
          The next file will be a different book name and so needs to read the first word, and use it.

          Samu 1
          \v 1:1	Kukuputuka Lizu apwilengako, kah
          \v 1:2	Ikiye apwilenga naKalunga kukupu

          \v 1:4	Muli Ikiye mwapwile Mwono, kaha 
          \v 1:5	Musana kana wamunyika mumilima, 
          \v 1:6	Kwapwile mutu vatumine kufuma ku
          \v 1:7	Ikiye ejile apwenga chinjiho wak
          \v 1:8	Ikiye kapwile Uze Musanako, oloz
          \v 1:9	Musana wamuchano apwile nakwiza 
          \v 1:10	Apwile hakaye, kaha kaye vakaten
          \v 1:11	Ejile kuvyenyi, kaha vaze venyi 
          \v 1:12	Oloze veshovo vamutambwile, vaze
          \v 1:13	vaze vene vásemuwile, keshi kuma
          \v 1:14	Jino Lizu alilingishile Ivene ku
          Samu 2

            @Terry-R It is the first word, but is repeated for each Chapter

              That appears to have worked.
              Wishing you a great day.

                Hi, @robert-or-janet-diebel, @terry-r and All,

                Robert, I’m really sorry because I did a mistake regarding my second and main regex replacement : I mixed two different tests :-((

                The correct regex S/R was simply :

                • FIND (?-is)\\v (?=(?s:.+?^(Chapter \d+$)))

                • REPLACE $1:


                But, I agree that the @terry-r’s use of the Edit > Line Operations > Reverse Line Order, in order to get the Chapter name after its contents, is quite clever !

                So, if we use the @terry-r’s method and taking in account your further posts, the task is really simplified :

                • Run an Edit > Line Operations > Reverse Line order action

                • Perform the following regex S/R

                  • FIND (?-is)\\v (?=(?s:.+?^(\u[\u\l -]+ \d+$)))

                  • REPLACE $1:

                • Run again an Edit > Line Operations > Reverse Line order action


                I used the regex (?-i)\u[\u\l -]+ for the book’s name, just in case you have this kind of title : My very-Best-Novel !

                BR

                  @guy038 Thanx very much. I am still working on this as the total project requires more changes.

                  All help is appreciated.
                  I am trying to do what I can myself, but am in over my head here.

                    Adds Book name fine, but all chapters show as “1”

                        Your last few posts aren’t referencing anybody. The @name you use is how to “speak” to a particular poster.

                        The posts are also lacking in detail so it is difficult to know what your problem is.

                        Suggest adding some examples showing before and after the change and what regex you used.

                          I have, a number of times, needed to grab a Value (usually a book name in this instance)
                          Then I need to fit it into a search as a parameter (maybe as a group) to be used in the Replace.

                          I believe you did that, but I am not sure how.
                          Could you expand a bit one the change you did from “Chapter” to BookName?

                                  Well your example is what I’d call the “before” example. How about show the same data but with the changes you’d need to make. As for a book name, I don’t even know where in your example the book name is, it certainly isn’t obvious.

                                  In fact the examples now are looking a lot more complicated than your initial example. That leads me to believe some of the earlier stuff was perhaps made up, and this is the real data. Whilst we are happy to help, I (personally) feel a bit used if it turns out the original solutions weren’t really needed.

                                  If you have a “real” request, please lay it out. We’ve had other posters in the past that “beat about the bush” and only through lots of posts do we realise their actual problem wasn’t the one they initially started with. That is just wasting time and quite frankly can cause friction.

                                    @Terry-R I am truly sorry about this.
                                    There is no attempt to deceive, or use.
                                    And I know you time is valuable by the depth of your responses.
                                    I have a number of macros. They were being executed in a certain order. Your responses help me to think there could be a better way. Maybe doing them in a different order. I am experimenting with that, and will continue.
                                    As stated earlier:
                                    I have, a number of times, needed to grab a Value (usually a book name in this instance)
                                    Then I need to fit it into a search as a parameter (maybe as a group) to be used in the Replace.

                                    The book Name here is “Kuputuka”. I am trying to help some folks who speak the Luvale language.
                                    I need to grab that word, and be able to use it.
                                    I will continue to search.
                                    Your help thus far has moved me forward in understanding some RegEx syntax.
                                    If I can come up with a better example I will post it.
                                    Again, sorry to have troubled you.
                                    Your input has been very much appreciated.

                                      Your help thus far has moved me forward in understanding some RegEx syntax.

                                      I think you are trying to run before you can walk. Learning Regex is like learning a computer language, albeit with a small number of defined “reserved words”. This is a common issue when we help out, of which we are well aware. Often we will try to describe what our solutions do. Sometimes we will point out the website regex101.com as entering the regex there, you will get a description (sometimes it doesn’t work as there are many flavours of regular expressions).

                                      I also offer up rexegg.com as that can be a great tool as well. But as with any learning it is best to start with basics, much as building a house. Start with the foundations and work your way up.

                                      It is good that you are trying to find your own way. Just be aware that we can help. Just be honest, show what you have tried, where it failed as you did in your first post. When asking questions give as much background information as possible and please include examples, both before and after the required changes.

                                      One of your statements “I have, a number of times, needed to grab a Value (usually a book name in this instance). Then I need to fit it into a search as a parameter (maybe as a group) to be used in the Replace.” suggests to me that this is 2 separate steps. Bear in mind that regex does NOT store values across steps. If a regex cannot grab and then use that parameter within itself then the process will not work. At that point it might be necessary to go to a proper programming language. Notepad++ supports several, PythonScript and LuaScript being 2 of them.

                                          @guy038 Your RegEx works great.

                                          (?-is)\\v (?=(?s:.+?^(\u[\u\l -]+ \d+$)))
                                          

                                          The BookName is the first word in the file so when line reversed it is the last.
                                          Could you explain how your RegEx grabs that last word and is able to use it?

                                          This project uses a number of MACROs. It would be helpful for me to understand how I can get the BookName from the file.
                                          As it is now, I need to alter the shortcuts.xml file too often.
                                          I have gotten the manual and am trying to figure it out but any help you could give would be much appreciate and might shorten my search substantually.

                                            Hello, @robert-or-janet-diebel ,

                                            Sorry, but I’ve been away since Friday on a ski course at the French resort of Val-Cenis ! Now I’m back and preparing my reply concerning my search/replacement, which I hope will contain all the necessary explanations !

                                            See you soon !

                                            Best Regards,

                                            guy038
