Finding and replacing all data between two points?

Joey Flaig

Yeah, this is what I was looking to do! This regex looks great… but it sometimes fuses the line indicating a speaker change [the ones with all the dashes that look like ----------------) with the dialogue! Any way to tweak the regex to prevent that?

If it matters, the speaker change lines contain 60 dashes!

Hi, @@joey-flaig and All,

I’ve got no much time, right now ! So try the exact regex, below :

SEARCH (?-si)^<ORIGINAL N°\d+>\R.+?\K\h*\R\h*+(?!<|-{5,})

REPLACE \x20

I’ll explain to you when I’m back, about six hours later !

Cheers,

And it seems like you could have a full time job, writing this person’s regexes!

Hello, @@joey-flaig and All,

So yesterday, my wife and I were accompanying 7/8 years old children ( our daughter’s class +2 other classes ), on a school trip and then, in the late afternoon, I preferred to watch the USA-Spain match of the women’s world football championship ! Of course, I wanted to know who France’s opponent would be ;-))

Ah ! I understood why the separation line, made up of 60 dashes, was missing in the original Joey’s post ! Just because, due to the MarkDown syntax, any line of, at least, 3 dashes produces a slight gray horizontal rule, instead ;-))

So, Joey, just forget, my quick previous post and let’s recapitulate all the process :

We’ll start with this sample text of 4 blocks, between the lines of dashes. In two of them, I placed some multi-lines text, inside the section <CLT 4>.............<CLT>

Using the regex S/R, below, we keep the interesting part of each block, from Joey’s point of view, of course !

SEARCH (?s-i)^\h*</ORIGINAL\x20N°(\d+)>.+?</COMMENT\x20N°\1>\R

REPLACE Leave EMPTY

And we get :

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<SPEAKER N°001>MAKOTO NAEGI</SPEAKER N°001>
<ORIGINAL N°001>
<CLT 4>Just some

Now, in order to change all multi-lines sections <CLT 4>.............<CLT> into a mono-line one, use the following regex S/R :

SEARCH (?-s)(?:(?!<|>|-).)+?\K(?:\h*\R\h*)++(?=(<CLT>)|.+)

REPLACE ?1:\x20

And here is your expected text :

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<ORIGINAL N°004>
<CLT 4>An other text to see how the regex works<CLT>

Notes on the 2nd regex :

First, the in-line modifier (?-s) means that the regex char . represents a single standard character, only !
Then, the part (?:(?!<|>|-).)+? looks for the smallest non-null range of standard characters, different from <, > and -, in a non-capturing group, till… … … the next main part
This main part is \K(?:\h*\R\h*)++ which resets the regex engine first ( \K ), then searches for any non-null blocks of EOL chars, possibly surrounded with blank characters, placed in a non-capturing group, without any backtracking in that part, due to the possessive quantifier ++
The final part (?=(<CLT>)|.+) is a dummy look-ahead structure, which defines an always-true condition ! Indeed, the block of EOL chars searched must be followed by, either, the string <CLT>, stored as group 1 or any non-null range of standard chars
The main advantage of this odd syntax is that, if the EOL chars are followed with the specific string <CLT>, we won’t replace with a space character but simply delete this EOL block, which can be achieved with the conditional replacement ?1:\x20, meaning :
If group 1 exists, replace with the EMPTY string
If group 1 does not exist, replace with a space character

I hope you and your family had a good time! It’s been a long time, but my dad still misses going on field trips with me and my class when I was younger. Precious memories! :DD I’m glad he was with me when I fell in the fish pond at the local zoo!

Thank you for all of this! This is so close, aaaaaaahhhh! I just realized - this would’ve been a lot easier if I’d just linked one of the transcript files:
https://drive.google.com/open?id=141c3d3ZBOb_GG3Psb9eQaaiWUl-g-ATF

I followed what you said to do in your most recent post. Doing the first regex (to cut out the extra data I don’t need) works, but when I do the second regex (to turn the multi-line dialogue into mono-line dialogue), the problem from my previous post still happens:

https://drive.google.com/open?id=11ChQl7D9YZ80COaxyadjjBl-tIp5aTPJ

I tried doing the mono-line regex first. Then that one did its job and looked like your expected text… but when I did the extra data removal regex after, then that one didn’t work!

Hi, @@joey-flaig and All,

This time, no trouble ! I’ve found the right regex S/R, which is, BTW, much more simple that anything else tried before !

As usual, having the exact bunch of data, to work on, is always the best solution !

After downloading your complete XML file, I noticed two things :

Some dialog do not begin with any tag <CLT ##> nor <CLT> => We cannot rely on these tags and should prefer to consider <ORIGINAL N°###> as an anchor :-))
When dialog is multi-lines, it is always split in two lines !
More anecdotal, your file is an UNIX file, with the UCS-2 LE BOM encoding

So, as a summary :

To remove the extra data, not needed, use the A S/R :
- SEARCH (?s-i)^\h*</ORIGINAL\x20N°(\d+)>.+?</COMMENT\x20N°\1>\R
- REPLACE Leave EMPTY
To change the two-lines dialog in a one-line dialog, use the B S/R :
- SEARCH (?-si)<ORIGINAL N°\d+>\R.+\K\R(?!-{60}|</ORIGINAL N°\d+>)
- REPLACE \x20

IMPORTANT :

Assuming your present data, your may execute the search/replacement B, first and, secondly, the A S/R ;-))
I’ve supposed that your separation line always contains 60 dashes, exactly. If not, change the value 60 , between braces, in the search regex, accordingly
Remember to click on the Replace All button, exclusively, when running the B S/R !

NOTES on the B new regex :

First, the part <ORIGINAL N°\d+>\R.+ looks for the complete line <ORIGINAL N°###> with its EOL character, followed with all the standard characters of the next line ( 1st line of dialog )
Then, the syntax \K\R resets the regex engine and it, now, looks the the EOL characters of the 1st line of dialog
But this search occurred ONLY IF the EOL chars are NOT followed with, either, a line of 60 dashes OR the string </ORIGINAL N°###>

Best regards,

guy038

Joey Flaig

@guy038
I wish I’d thought to send you the files themselves at first, haha! You’re great!

The B S/R regex to turn two-line dialogues into one-line dialogues works like a charm!

However, the a S/R regex to remove the extra data doesn’t seem to work at all. I tried it in the order of B + A, then A + B, and even A by itself, but it’s not doing anything. I made sure to always use Replace All for both regexes. Is there a setting I shouldn’t have checked?

Also, if it matters - I’m using the 32 bit version of NPP [I had to in order to use the Combiner plugin]

Hello @@joey-flaig and All,

Aaaah ! As soon as I saw the picture of your text, in the background, I understood what happened ;-))

Of course, considering the first entry N°001 and supposing you’ve executed the B regex S/R first ( 46 occurrences replaced ), I was expecting :

<SPEAKER N°001>KIYOTAKA ISHIMARU</SPEAKER N°001>
<ORIGINAL N°001>
Would you like to study with me, Makoto? Just the two of us?
</ORIGINAL N°001>

<COMMENT N°001>

</COMMENT N°001>

But, seemingly, you’ve already changed the N°001 entry, as below :

<SPEAKER N°001>KIYOTAKA ISHIMARU</SPEAKER N°001>
<ORIGINAL N°001>
Would you like to study with me, Makoto? Just the two of us?</ORIGINAL N°001><JAPANESE N°001>

</COMMENT N°001>

It easy to see why this new text layout breaks the logic of the A search regex. Indeed, I, initially, supposed that the part </ORIGINAL N°001> was, always, at beginning of lines !

So, the final S/R A becomes :

SEARCH (?s-i)(^)?\h*</ORIGINAL\x20N°(\d+)>.+?</COMMENT\x20N°\2>\R

REPLACE ?1:\r\n

Notes :

This new A regex looks for the string </ORIGINAL N°###>, possibly preceded with blank characters, at any location of current line, due to the optional syntax (^)?
In replacement, 2 possibilities :
- If the string </ORIGINAL N°###> is at a beginning of current line, the group 1 exists, so the conditional replacement ?1 rewrites all text before the : char, so … nothing
- If the string </ORIGINAL N°###> is located elsewhere, the ^ location is not true. So the group1 is not defined and the conditional replacement ?1 rewrites all text, after the : char, so a line break \r\n

That’s all ;-)) This time, you should see the message Replace All: 82 occurrences were replaced

Remark : Of course, I, also, verified that your new text layout does not break the logic of S/R B !

Cheers,

It works! Thank you so much for all the help, and for accommodating my requests and frequent regex-breaking! It means a lot to me, and you’ve saved me soooo much time and hand pain!! Is there any way I can make it up to you? I could draw you something :D

guy038

Hi Joey,

Thanks for your kind words ! You said :

Is there any way I can make it up to you?

Thanks, but I don’t need anything !! I’m just pleased that the last regexes are the good ones for your specific file !

This is the main point, indeed ! Regexes are very, very, very sensitive to text layout. So, once I’ve built up some regex for an OP, based on his provided examples, the OP should not add, delete or modify anything of the original text, in the meanwhile, as, probably, the regex will not work anymore ;-))

As far as possible, anyone, asking for regex solutions, should consider all cases of text layouts, of the original file to modify ;-))

It’s generally, not so obvious, and, in my personal work, I simply create successive versions of the regex to get a final version which handles all reasonable cases !

I say reasonable ( and not possible ) because, sometimes, we can’t think about all the possibilities and, anyway, this could lead to an huge and useless regex ;-))

Best Regards
