replace / move numbers from one row to another with regular expression (in parentheses)

@Terry-R said in replace / move numbers from one row to another with regular expression (in parentheses):

So from your example it appears that file 1 isn’t changed, only file 2.
And I can see that file 2 lines have different wording. How do you determine which line in file 2 gets which number? Is it that the number in line 1 of file 1 gets copied to file 2 line 1? Or do you have some other rule used to determine which. To make a solution we need a rule to follow, something that can be translated into either a regular expression or some other function if a scripted solution.

I think of something. First, I will select all numbers from parentheses (including parentheses)

SEARCH: .*?($.*?$).*

REPLACE BY: \1\2

So, I will get:

(22)
(18)
(23)

(2)
(12)
(10)

Now, all I have to do is copy the first 3 rows instead of the next 3 rows to get:

(22)
(18)
(23)

(22)
(18)
(23)

The problem is, how do I copy the parentheses and numbers back to their place between tags?

Not sure where you are heading but you still haven’t answered my question.

I’m going to take a punt since it does seem a bit obvious from the examples:

both files contain the same number of lines and are in the same order, line 1 of file 1 corresponds with line 1 of file 2.
I’d prefix each line in each file with an ascending number 1,2,3. I’d also prefix (behind the number) and “a” for file 1 and a “b” for file 2.
I’d then combine both files and sort lexicographically.
I’d use a regex to copy the number from #a line and replace the equivalent number in the #b line, at the same time removing the #a line (since we don’t need the file 1 line anymore).
I’d then remove the prefix from the lines (#b) leaving the changed file 2 content.

ok, I made a regex, it is kind a step forward. I managed to move the numbers and parentheses from the first 3 rows to the next 3, but not in the correct order.

SEARCH: (?s)(<li><a href=)(.*?)($\d+$)(<\/a><\/li>).*?\K(\w+)

REPLACE BY: \3

if I could do that, it’s a sign that it’s somehow possible. but I am not very good at regex. Maybe @guy038 will improve my regex . :)

Hi, @robin-cruise, @terry-r and All,

Sorry, but a significant lot of information is missing for a good comprehension of your goal :

How many lines <li><a href="page-##.html" title="Page ##">Page ## (##)</a></li> contains your File 1.html file ?
Are all these lines consecutive ?
Even if some of these lines are consecutive, are there some other similar sections, containing this same type of lines ?
Does the File 2.html file contains the same number of lines <li><a href="page-##.html" title="Page ##">Page ## (##)</a></li> than the File 1.html file ?
If the File 2.html file contains also some sections of these lines, is the layout quite identical, between the two files ?

In short, could you provide a larger part of your files to get a more precise idea of the changes to do ?

Best Regards,

guy038

both of them, File 1.html just like File 2.html contains 40 lines. both files have the same structure, except the numbers in parentheses.
The numbers (in parentheses) are different on both files, but I want them to be the same. Right no, they are not consecutive numbers, but random ones.
page-1.html" title=“Page 1”>Page 1 is a short version, just an example.

The real pages are like: <li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (22)</a></li>

Basicaly, it’s about a meniu on a website translate in 2 languages, and that number in parenthesis , ex. (22), is the number of the articles on that section. Should be the same numbers in both languages

Did you ever read my questions? Specifically I asked whether the same number of lines in each. Also is line 1 in file 1 equal to line 1 in file 2, thus the line 1 number (##) copied across to line 1 in file 2.

If so then I have already provided the solution in words (just needs translating into code), which I wrote out for you. Since you seem to have a good idea on how to create regexes, did you not try to follow my instructions?

Given these condictions and if you are allowed to install the LuaScript Plugin, there is a script than can select, copy the numbers in parentheses from one page and paste them in the other.

Please confirm and will provide further details.

Take care and have fun!

sorry for my objection , but it looks easier to just change the wording of the file2 to make it fit file1 and keep the numbers untouched . so file 1 would get replaced and translated by file2 which is the right one concerning the numbers. idk

Robin Cruise

this solved the problem.

In short, I copy all text before the parentheses from File 1 into the column A from EXCEL. Then I copy the parentheses with numbers from File 2 into the column B from Excel, put the rest after the parentheses into the column C from Excel. Then select all Excel columns into FILE 2, and replace line. Now the parentheses are identical.

Step 1 - Use regex to select all parentheses (with numbers), then copy them to an excel in column 2

SEARCH: .*?($.*?$).* REPLACE BY: \1\2

Step 2 Use regex to select everything on each line before the parentheses:

SEARCH: $.*$.* REPLACE BY: (leave empty)

Step 3 - Copy the resulting lines to an excel file in column 1

Step 4 - Copy directly to column 4 of excel what is after parentheses: </a></li>

or use regex to obtain this result </a></li>, select everything after round brackets SEARCH: ^(.*\)).* REPLACE BY: \1

Step 5 - Copy all excel content to a new notepad ++ file.

If there are too many empty spaces, search and replace 2 spaces with one space

Hello, @robin-cruise, @terry-R, @astrosofista, @carypt and All,

Sorry to be very late, as I answered to many posts, recently !

Here is my method :

Open your File 1.html and File 2.html files in N++
At the end of the File 1.html contents, insert, for instance, a new line =====
Append the File 2.html contents, right after that new line

Note that we’ll need two specific characters, which are not used yet in your HTML files :

One char to separate the contents of the two files, in *File 1.html**. I chose the = sign. Hence the line of five = signs
One char used by the regex S/R in order to mark the numbers between parentheses already processed. I chose the # character
Of course, you may choose any character for these two specific chars. Just modify the regex, accordingly
Preferably, avoid the true regex symbols \ ^ $ . | ? * + ( ) [ ] { }

For instance, after merging the File 2.html contents into File 1.html, we would obtain this tiny text, with the ===== separation

<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (22)</a></li>
bla bla
bla bla
bla bla
bla bla
<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (18)</a></li>
bla bla
<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (23)</a></li>
=====
<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (2)</a></li>
bla bla
<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (12)</a></li>
bla bla
bla bla
bla bla
bla bla
<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (10)</a></li>

Move to the very beginning of File 1.html
Open the Replace dialog ( Ctrl + H )
- SEARCH (?s)$(\d+)$(.+=====.+?)$(\d+)$|^=====.+|#(?!.*^===)
- REPLACE ?1$\3#$\2$\3#$
- Untick, if necessary, the Wrap around option
- Select the Regular expression search mode
Now, keeping the Replace dialog opened, click on the Replace All button ( or preferably hit the Alt + A shortcut ) repeatedly, until the message Replace All: 0 occurrences were replaced from caret to end-of-file is displayed !

And you’ll get the expected File 1.html contents :

<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (2)</a></li>
bla bla
bla bla
bla bla
bla bla
<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (12)</a></li>
bla bla
<li><a href="Love-Master-A-Manga-Volume.html title=“Love Master A Manga Volume”>Love Master A Manga Volume (10)</a></li>

Save the new File 1.html contents, with all the updated numbers between parentheses !

Notes :

For N Replace All operations processed, in totality :
- The N - 2 first operations :
  - Replace the numbers of File 1.html with the corresponding numbers of File 2.html, located after the ===== line
  - Add a # marker to the two numbers processed
- The N - 1 operation deletes from line ===== till the very end of file, in order to suppress the temporary appended part
- The N operation deletes all the existing # markers, of the File 1.html

Best Regards,

It’s fairly “easy”: :-)

?1 controls the rest of it: If capture group #1 was NOT matched, the replacement is “nothing” (aka deletion)

If capture group #1 WAS matched, then the replacement consists of:

opening parens: (
what was matched with capture group #3
a literal #
closing parens: )
what was matched with capture group #2
opening parens: (
what was matched with capture group #3
a literal #
closing parens: )
