Find/remove duplicate multiple lines and keep the first occasions



  • Hi,

    I’ve read a lot of topics now, but still can’t find it. I have a file with a lot of text, it is a save in html from a textbook. In this html is above every paragraph the module-title and the topictitle printed…I only want to keep the first appearence. I did it by hand by search and Replace, but it will take ages if I have to do this for the whole book, multiple times.

    I tried the string in the S/R box: (?s)<some thing>\R[^\r\n]?\R)(.?)\K\1 but it came back with that it isn’t a function…
    (?s)(<div class=“element”><div class=“learning-text__title–h1”>Groene chemie</div><div class=“learning-text__title–h2”>Wat is groene chemie?</div><div class=“learning-text__title–h3”></div>\R[^\r\n]?\R)(.?)\K\1

    And because it are multiple lines, I can’t use reordering the lines legicon…, because I wouldn’t know which would belong to which.

    So, the first question is: How do I remove every occasion except the first occasions of the titles?
    The second question will be “can I automate this proces for multiple modules and chapters”?

    But the first is the most urgent for me…

    I manually removed the next part in the first chapter to get the result what I wanted:

    					<div class="element">
    				<div class="learning-text__title--h1">Groene chemie</div>
    				<div class="learning-text__title--h2">Wat is groene chemie?</div>
    				<div class="learning-text__title--h3">
    					
    									</div>
    

    In the second chapter I removed:

    					<div class="element">
    				<div class="learning-text__title--h1">Groene chemie</div>
    				<div class="learning-text__title--h2">Kan het wat sneller?</div>
    				<div class="learning-text__title--h3">
    					
    									</div>
    

    I think you wil get the idea by know? I don’t know if this is information enough to work with…

    Below is an example of the text that isn’t edited by me, except that I replaced the texts from the paragraphs with … (copywright etc) and inserted “NEXT CHAPTER.”

  • @W-den-Boer

    Sorry, I’m confused. You’ve deleted

    					<div class="element">
    				<div class="learning-text__title--h1">Groene chemie</div>
    				<div class="learning-text__title--h2">Kan het wat sneller?</div>
    				<div class="learning-text__title--h3">
    					
    									</div>
    

    ?? But how is this a duplicate? Groene chemie is a duplicated line but *** Kan het wat sneller? *** is not isn
    t it.

    If you want to delete duplication from within one chapter the first thing to find out is how a chapter can be described?
    Where does it start and where does it end. If this is unique, then one might be able to use a regex to answer that question.



  • Well, it’s unique per chapter. The module-name is “Groene chemie”, the first chapter name is “Wat is groene chemie?”. The first chapter consist out of multiple paragraphes, in the example I uploaded the first is “Inleiding: wat is duurzame ontwikkeling?” and the second is “Zuinig met grondstoffen”, the third is “Wettelijke verplichtingen op het gebied energie”…I’ve deleted the others because of the length.

    The next chapter has again a unique repeating sequence, again “Groene chemie” but now with “Kan het wat sneller”.

    The whole textbook-html consists of 9 modules, each with about 10 chapters which have multiple paragraphes… I won’t mind if I have to copy-paste each “block” I want deleted and then run the function, but I do mind it the way I do it now. Now I go through the text, see if a new chapter starts, copy the complete set like I posted and search/Replace with nothing on it. But I accidentally delete the first one a lot…and have to scroll down to the next and repeat. Or sometimes I don’t scroll down but use the Search-function with “<div class=“learning-text__title–h1”>Groene chemie</div>”, because the others in this topic are now deleted it will bring me to the next chapter.
    Manual repetitions will create a lot of errors. I wan’t notepad++ to do it for me.

    I manually edited the code from my first post to how I want it to be afterwards.

  • @W-den-Boer

    Ok, deleting the duplicated lines is not the problem,
    but that the HTML tags remain intact, i.e. besides the duplicated lines,
    the closing </div> tags must also be deleted, correct?

    In the posted examples it looks like the 2nd occurance, the first one is not touched,
    are these lines:

    			<div class="element">
    				<div class="learning-text__title--h1">whatever</div>
    				<div class="learning-text__title--h2">whatever</div>
    				<div class="learning-text__title--h3"/>
    

    each further lines then like this

    	</div>
    	<div class="element">
    		<div class="learning-text__title--h1">whatever</div>
    		<div class="learning-text__title--h2">whatever</div>
    		<div class="learning-text__title--h3"/>
    

    and finally the closing tag of the last duplicate

        </div>
    

    Is that so? Or is your html data much more complicated?



  • @W-den-Boer said in Find/remove duplicate multiple lines and keep the first occasions:

    I only want to keep the first appearence.

    I’ve taken the last couple of examples (before and after) and compared them in depth and can see you need to remove the string:

    *					<div class="element">
    *				<div class="learning-text__title--h1">Groene chemie</div>
    *				<div class="learning-text__title--h2">Wat is groene chemie?</div>
    *				<div class="learning-text__title--h3">
    *					
    * leaving CRLF									</div>
    

    when this exact sequence has already occurred (it hinges on the h1 and h2 tag data). Disregard the * as I used these to determine what needs removing. I note the last line removed leaves behind a CRLF (carriage return line feed) and thus that creates the empty line you have. I’m not sure if this was intentional, but it can be removed or not, your choice.

    The concept I’m coming up with is something you mentioned in the first post, of not being able to sort lines etc. Well, actually you can. The steps I’m suggesting are:

    1. number ALL the lines with a numerical increasing value adding 1 to each line, this is achieved by using a NPP built-in function.
    2. cutting out just those sequences of lines which we need to process to another file
    3. processing these to remove the duplicates (this will actually most likely be multiple steps).
    4. returning the remaining lines back to the original file.
    5. sorting the lines by the original numerical value. there will be gaps in the numbers but that doesn’t matter as they will still appear in the correct order.

    Now the main reason for processing the lines separately from the original file is that although there is a way to do it in the original file, if that file becomes very large there is a chance the process will incorrectly select ALL lines and remove them. this is a known fault which rarely occurs but is an issue when dealing with requests like yours. I tend to just avoid being in that situation like the plague, hence removing the lines and processing separately.

    Terry



  • @Ekopalypse I think I understand what you ask…no, the document is not more complicated. It just has a lot of different chapters…and I have 2 versions, for different levels…
    And it can be I have to do it more in the future, when updates are made.

    I don’t mind half an hour repeating steps, but this is a lot more if I can’t get it at least partially automatic.
    I don’t understand how I can make an experssion that takes a block of lines and removes all the blocks but the first. If I can do that, then I can create a set of that expressions for each chapter and I copy-paste them. Or find a way to make it into a macro…

    Again, thanks for the thinking.
    And I don’t mind about the closing </div>, but it seems adequate to remove it since it closes a div in the portion that is removed, or not?

    Wdeb



  • @Terry-R It seems to me I’m missing at least 2 steps.

    • Automtion…step 2 and 3 means I have to go through the whole file each time? Or is there a trick you had in mind

    • Removing the numbers I added in step 1 (I presume you mean inserting it by ALT-C)

    But, I’m considering ordering Legic…and see what happens…

    Wdeb



  • @W-den-Boer said in Find/remove duplicate multiple lines and keep the first occasions:

    But, I’m considering ordering Legic…and see what happens…

    I’ve got the process boiled down to a few steps and yes it should be able to be made into a macro, might be 2 macros since I’m working across 2 files. Still have some fine tuning and presentation to achieve. I will be back at my work PC in approx 5hrs where my notes are and it should only take about 1hr to knock together the steps for you.

    I have 2 questions. I originally thought the blank line in your “after” example was the result of leaving the CRLF from the last line when the 6 or so lines are removed but I now think it was due to an actual blank line in the sequence which you never removed. Since this is html code this blank line probably should be removed, do you agree?
    2nd question, is it sufficient to ONLY use the h2 tag data to determine duplicity or should every title sequence need to test both h1 AND h2 tag data?

    I originally thought the duplicity test would be the hardest but it came together in just 1 step. It might even be possible to try it within the file now I’ve been testing so I will likely give you both processes as there is very little difference between them.

    Terry



  • @Terry-R First: Thanks.
    Second: Q1, A1: I checked, the only blank line in the original file (in the textbook-part) was here

    				<div class="learning-text__title--h3">
    blank					
    									</div>
    

    Q2: A1: I do think that the text between the h2-tags is also in the textbook as plain text. So only that text will result in more removals and not only the h1 and h2 and h3 etc tags. But if your duplicitysearch includes the notion it has to be next to h1, I think you’re right.

    Q2: A2: I need only unique sets of h1/h2 left in the document. Each h1 will be there about 10-16 times (depends on how many paragraphes there are), but each paragraph (h2) will be unique.

    Wdeb



  • @W-den-Boer said in Find/remove duplicate multiple lines and keep the first occasions:

    But if your duplicitysearch includes the notion it has to be next to h1, I think you’re right.

    My duplicity search/removal works on the 6 lines (exactly) which encompasses the h1,h2 and h3 tags. I note in your examples h3 is never used. Is that true for the entire file?
    How many lines in the whole file, this will give me confidence on whether to aim at doing it within the 1 file or extracting, processing then returning remaining lines back to original file and completing the processing.
    Currently my testing, as it is carried out in a separate file will only work on the sets of 6 lines of title data around the h1,h2 and h3 tags. Therefore no issue of removing too much as it does not see any of the “plain text”. If I keep it within the 1 file I will need to further test, but I feel it still won’t test against the “plain trxt” as I keep the test within those sets of 6 lines

    Terry



  • 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 :

      1. Backup your file
      1. Change the multi-lines block, above, in one single line, in your file
      1. Add a numbering at beginning of all lines of your file
      1. Bookmark all the new “single lines” of your file
      1. Paste these lines in a new temporary file
      1. Delete each first line of an identical lines block, in the temporary file
      1. Append the remaining lines of the temporary file in your file
      1. Delete all lines of your file which is repeated in the appended part
      1. 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 )

    If necessary, I could give you, next time, some hints on the regexes involved in the process !

    Best Regards

  • @Terry-R h3 is never used, yes. At least, not as I saw it. The total file has around the 10.000 lines.



  • @guy038 Ofcourse I tried this. I even understand the steps…but… the result of step 7 leaves a blank file. 2020-09-22_20-30-05 Result step 7.png

    Is that the problem Terry revered to?

    And I had a @ in my file, so I replaced with `, which was not in my file.

    Wdeb



  • And I tried it with one module, same result.



  • Hi, @w-den-boer, @ekopalypse, @terry-r and All,

    Unfortunately, you’re right about it ! Indeed, it’s the problem that @terry-r referred to :-(

    Just an example : imagine there are about 3.000 lines between a pseudo single line to delete and the same line, near the end of file, listed after the ====.... line. Then, It is very likely that a false positive match ( all file contents ) occurs !

    But, luckily, I’ve got the right solution :

    • Step 6 : Simply append the contents of new 1 file at the end of your file ( NO need to add the line of = signs ! )

    • New step 7 : Sort all the lines => The duplicate lines will, then, be all consecutive ! ( I should have thought about it . Obvious, isn’t it ? )

    • New step 8 : Modify the third S/R in order to replace two equal consecutive lines, with only, the numbering and a line-break character

    • New Step 9 = Old step 8 almost unchanged !


    So, here is my updated method :

      1. Backup your file
      1. Change this multi-lines block in one single line, in your file
      1. Add a numbering at beginning of all lines of your file
      1. Bookmark all the new “single lines” of your file
      1. Paste these lines in a new temporary file
      1. Delete each first line of an identical lines block, in the temporary file
      1. Append the remaining lines, of the temporary file, at the end of your file
      1. Sort all the lines of your file, lexicographically ascending
      1. Replace all two consecutive duplicate lines of your file with a single line ( Numbering + Line-break char )
      1. Restore the initial appearance of the file ( Rewrite the missing line_break characters and delete the leading digits )

    • 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 )

    • Paste the contents of the clipboard under the ===.... line ( so, the new 1 contents )

    => You should get the following Text_Book.txt contents :

  • @W-den-Boer said in Find/remove duplicate multiple lines and keep the first occasions:

    Is that the problem Terry revered to?
    And I had a @ in my file, so I replaced with `, which was not in my file.
    Wdeb

    I have an alternative to @guy038 solution, shorter in the number of steps and maybe a bit easier to process. It’s the solution I referred to but all in the one file.

    Surprisingly I just ran a test on a dummy file containing 50K+ lines and a size approx 5MB, it all worked in the file, no need to export. So I will provide the steps which you can execute manually for now as I’m still concerned that in your tests the fault I explained about DID occur. For all search and replace functions below the “Search Mode” MUST be “Regular Expression”. Turn “Wrap around” off and make sure cursor is in the very first position of the file.

    1. We will add line numbers. Yes we use the Ctrl-C function (Column Editor). I prefer to delimit the line numbers with a weird 2 character sequence so there will be no issues differentiating the inserted sequence from the original code. Make sure the cursor is in the very first position then add “#@” to start of every line, then add line numbering with leading zeroes. So with Column Editor we can either insert characters or numbers, the first run is with the #@ character sequence. Leave the cursor in the first position and repeat Column Editor, this time with the numbers, starting 1, incrementing 1 and tick leading zeroes.

    2. We sort the lines into “Integer Descending” order. Doesn’t sound right but in fact there is a method to this madness. In my testing I stumbled across the fact that by doing a decreasing sort the “title” sequences to be removed were the first ones of any pair. My regex (regular expression) grabs the first set, then compares with a look-ahead to the next set. If they are the same the set already captured are removed. This allows for the entire file to be processed in a single pass. Now this is likely where you will again stumble into the fault. If so I do have another alternative if my assumption is correct. That is, as this is a “book” duplicate titles (h2 tag data) will ONLY ever be sequential. They will always occur in groups, not randomly throughout the file. Is that assumption correct?

    3. Use the Replace function to remove duplicates
      Find What:(?-s)(^.+\R){3}.+title--h2">(.+)</div>\R.+title--h1">(.+)</div>\R(.+\R)(?s)(?=.+?\2(?-s).+\R.+\3)
      Replace With:empty field here, nothing
      Replace All button
      Currently it uses both h1 and h2 to determine duplicate status, As you suggest h1 does NOT change then this regex can be made simpler?

    4. Re-sort the file into integer ascending.

    5. Remove the line numbers using The Replace function
      Find What:^\d+#@
      Replace With:empty field here, nothing
      Replace All button

    6. Hopefully completed as expected.

    I did decide in light of what has been referred to, to remove that “blank line”. I see no need for it in a html coded file. It doesn’t really help with the viewing, as in editing of the file. Please do confirm one way or the other on whether you need this line or not. My processes above can be adjusted to suit. In my testing on a couple of the steps I went to run the regex only to find a previous step had left the first word in the file highlighted. This meant the regex was working on a selection ONLY. If this occurs, just click in the file’s very first position again before doing the next step.

    Please read all the above steps and be familiar with the overlying reason for each of the steps (the regex itself doesn't matter). If at all unsure on what is occurring post back and it can be explained in more detail.

    I especially (and I think many others) will be VERY interested in knowing how my process went.

    Cheers

  • @Terry-R I think it works. In step 1 it is ALT-C insteed of CTRL-C

    I have to compare it to the one I made, but here in the Netherlands it is late. So tomorrow. And I see you made the selection relative to the h2/h1 tags. Don’t understand it completely, but that;s what I make of it.

    Thanks, I’m gonna check the Guy-method too and in the end compare it…

    Will let you know.

  • @guy038 Thanks for the changes.
    I know have two files, one by method of Terry and one by method of Guy.

    Strange thing happens in the Guy-method. Module 1 is not correct and every title got removed, but from module 2 it seems correct. I think that the problem is caused by a fault in my document, but as I said…tomorrow. Thanks both.

    Yes, my bad. I didn’t actually check that hotkey, thought I knew it although that is the copy command DUH!.

    My quick test earlier was not a good one as I replicated a few sequences many times. So the regex never needed to search the entire file. However I just repeated the test, again with a 47K+ line file with only 1 pair of titles, one at the start and another very near the end. It still worked so I am very hopeful that your real life data should also work.

    The regex does indeed use both h1 and h2 tags to identify where it is. At the point the h2 tag line is found it has the preceding 3 lines as well. Now note we look for h2 not h1 as currently the file is reversed, so h2 comes first, actually h3 does but it does not contain any data. Then we continue on to capture the h1 data. both h2 and h1 are used in the look-ahead (?=.+?\2(?-s).+\R.+\3) to see if another sequence also has that same h2 and h1 data. In which case the regex is confirmed and the first set is removed.

    So I will work on removing the need to test for the h1 tag, leaving just the h2 tag as the identifier of a duplicate set. Also as this “seems” to work within the file (no export required) I might also be able to create a macro which then all you have to do is insert that into one of NPP’s configuration files. More on that later.

    So outstanding question(s):

    1. As this is a “book” duplicate titles (h2 tag data) will ONLY ever be sequential. They will always occur in groups, not randomly throughout the file. Is that assumption correct?
    2. The “blank” line. What is your requirement, keep or discard?

    I’ve been doing a lot of testing and still can’t guarantee it will work correctly every time within the 1 file due to the fault previously mentioned. I’ve had success on a 50K line file, then on another occasion failure on a 10K line file.

    However there is a bright side, most of the steps can be automated into a macro, even when using the 2 file system (cut selected lines and insert into a temporary file). However all is not perfect. The initial steps of numbering the lines does NOT convert to a macro. Thus the steps to include the line number and #@ (my idea) must be completed manually. I do feel though that this a minor irritation.

    Macro’s are saved within the shortcuts.xml file. Depending on how your installation was completed it may be in one of several locations. I’m going to use the way mine is setup, it will be up to you to find the correct file (same name) if it’s not the one I’m using.

    1. Open Notepad++ (I’m going to call it NPP from here on) without ANY files being open (like a saved session). We need to operate this NPP session purely to edit the shortcuts.xml file ONLY!
    2. Select “Open…” and type %appdata% and press enter. This will open a folder listing (amongst other things) the Notepad++ folder. Double click to open this folder. Within it is the file we seek; shortcuts.xml; double click to open that file.
    3. Look within the file for a start tag of <Macros>. There will also be a ending tag </Macros>. Within this there may already be a macro recorded, if so it will be surrounded by the tags <Macro> and </Macro>. What you will do is copy the contents of the box below and insert into this area so it becomes a new Macro. So insert immediately before the </Macros> tag, but NOT in between the <Macro> and </Macro> tags as that will affect another macro, should it exist.

    Note I called this Macro 20027 (first line within box) in recognition of your post/topic number. Feel free to change this to a more suitable name upon inserting.
    4. Save the shortcuts.xml file and exit NPP, very important no other work is carried out in the current session!
    5. Re-open NPP and now under the Macro menu option there should be an item called in my case 20027, your’s whatever you named it to.
    6. That completes a one off process to get the macro “recorded”. Now comes the best bit, actually processing one of your files.

    1. So start NPP, again NO other files loaded, very important!
    2. Open the file you need to edit.
    3. Place cursor in the very first position of the file and open the “Column Editor”. First place the characters #@ as has previously been explained. Then repeat for the line number.
    4. Make sure cursor is again in the first position.
    5. Click on the Macro you created (20027).
    6. Hopefully the process is fairly fast, for me on an almost 10K line file it took about 5 seconds.
    7. The file you opened should now be without the duplicated titles, be aware that at the point the macro ceases the file is “edited” but NOT saved!. You will also have a second tab which is the title sequences which were edited. This is only a temporary file and does not need saving, close it.

    Obviously you will need to proof the changes made, I strongly suggest to do so. One way of determining the number of changes is to use a copy of the file (this is a destructive test), remove ALL but the h2 tag lines. Then sort and run your eye over the list to see what duplicates exist (if lots then a regex could identify them more accurately, you do seem to be somewhat regex aware so I leave that to you to do). For any duplicate use the tag data string (with the h2 tag string so it does not check “plain text”) to “Count” (within the Find function) on the original processed file, count should always be 1 ONLY!

    So it is very hard to decipher a macro once created, although there are amongst us some “experts” in that field (NOT ME!), there is also some documentation should you feel the need to do so which will help.
    What this macro does is:

    1. Bookmarks the 6 line sequences throughout the file, then cuts the bookmarked lines and inserts into a “new tab”, that’s the temporary file I referred to above. I should mention here that I’m using version 7.8.9 64bit as I believe the bookmarking function originally only marked the first line of a sequence of lines, it now bookmarks all the lines a regex selects in this version.
    2. Sorts in Integer descending order.
    3. Removes the duplicates using ONLY the h2 tag data as the identifier. The blank line is removed as part of the sequence of 6 lines.
    4. Copies the remaining lines back into the original file and re-sorts integer ascending.
    5. Removes the line number and following 2 character delimiter.

    Just check as there may be a straggler blank line either at start or end of the file. I came across that in testing and was never sure from where it came from. From a html coded file a blank line is inconsequential so I’ve haven’t been too bothered about it.

    I’ve quite enjoyed getting my teeth into a major bit of work so I thank you for supplying it. I will say though that my “dummy” data can never replace “real” data so you may well find issue with it. I’d be only too happy to take another look should that arise. Regexes such as this can be a bit fragile (although we do try to build in some flexibility) so any change in the input could well stop the process, or at least cause a malformed file, so continue to do spot checks.
