Finding multiple lines in multiple files and deleting just those lines

could I just use the regex (?-is)^.+Sync by honeybunny - corrected by chamallow35\www.Addic7ed.Com\Sync by yyets.net - corrected by chamallow35\www.addic7ed.com\Please rate this subtitle at www.osdb.link/6hdjt\Help other users to choose the best subtitles.*\R

Hi, @steve-wilson,

Ah, yes ! Of course, if you already placed strings, like First line to remove or Second line to remove…, in your files, just change my previous regex, as below :

(?-is)^.+\[.*line to remove\].*\R

Notes :

The modifiers (?-is) were explained previously
Then the regex matches, from beginning of line ( ^ ), any non-empty range of standard characters ( .+ ), ending with an opening square bracket symbol ( \[ )
Then matching any range, possibly empty, of standard characters ( .*), ending with the string line to remove, with that exact case, and the ending square bracket symbol ( \] )
And, finally, matching any remaining range of characters, possibly empty, of the current line ( .* ) , along with its End of Line characters ( \R ), which may be \r\n for Windows files, \n for Unix files or \r for Macintosh files
And, as the Replacement field is empty, the complete matched line, with its line-break, is, thus, deleted

Remarks :

The square bracket symbols, being regex symbols, must be escaped to be considered as literals !
Any syntax [...... line to remove], whatever text is, between the [ symbol and the string line to remove will be taken in account by the regex and the corresponding line selected for deletion

Cheers,

I REALLY do appreciate all the time you’ve put in here. I’m just not getting it. I’m going to need to input at least a dozen lines that I want gone, but if you could show me an example of a regex to remove the following six lines, it’d be terribly helpful.

I’ll quickly wade in here.
Of the examples provided and knowing that the subtitle files are for movies I’d suggest you can group some of the lines you wish to remove. For example it’s very unlikely some dialogue would include www. or <font color or even Sync by. So in effect you may not need to actually write out the lines in full. you just need enough information to uniquely identify the lines you want to remove.

May I also suggest you combine ALL the files together, order them and remove duplicates. Look at what’s left. This could quickly identify what you’re trying to remove. Then using that information you get a regex to run over the original files.

@steve-wilson, and All,

Very sorry, because we posted, rather simultaneously :-((

Your last post goes towards a completely different direction ! The syntax, that you described, cannot be used in that form !! The regex would be quite invalid :-((

So, first, are you searching these six sentences, below, with that exact syntax ?

<font color="#ffff00">Sync by honeybunny - corrected by chamallow35</font>
<font color="#ffff00">www.Addic7ed.Com</font>
Sync by yyets.net - corrected by chamallow35
www.addic7ed.com

I mean, could it be that, sometimes, you get lines with chamallow73 instead of chamallow35, OR these six lines never change, in all your files ?

If these 6 lines have a fix form, the generic regex, to use, is :

SEARCH (?-is)^(.*\Q...Line 1 Contents...\E.*|.*\Q...Line 2 Contents...\E.*|.*\Q...Line 3 Contents...\E.*|..........|.*\Q...Line 6 Contents...\E.*)\R

Notes :

...Line #n Contents... represents any the exact part, of the nth line, what you want to search
The \Q and \E escaped sequences ensure you that any text placed between these two boundaries, is taken, literally
The | symbol is a regex symbol to separate different alternatives to search, simultaneously
The .* syntaxes, located, before \Q and after \E are the areas, possibly empty, located before and after your different sentences to search. Note that, if a sentence represents all the contents of a line, you may suppress these .* syntaxes, in the corresponding alternative
Finally, any possible alternative, between parentheses, must begin a line ( ^ ) and ends with its line-break characters ( \R )

If we apply this generic regex to your real example, we get the following regex :

(?-is)^(.*\QSync by honeybunny - corrected by chamallow35\E.*|.*\Qwww.Addic7ed.Com\E.*|.*\QSync by yyets.net - corrected by chamallow35\E.*|.*\Qwww.addic7ed.com\E.*|.*\QPlease rate this subtitle at www.osdb.link/6hdjt\E.*|.*\QHelp other users to choose the best subtitles\E.*)\R

Et voilà :-))

P.S. :

I strongly advice you to read this FAQ post, on regexes, below :

https://notepad-plus-plus.org/community/topic/15765/faq-desk-where-to-find-regex-documentation/1

The search mode is regular expression and wrap around is ticked.

Note that I haven’t included the complete line as I think the strings I’m searching for are unique enough. The .+\R sequence at the end means as long as it starts with one of the strings, also grab the remainder of the line. The ^ at the start makes sure we are starting a search at the start of a line. Thus if these strings are NOT at the start of the line, they will not be removed.

The regex includes a pipe character between the different strings (|), this allows the regexe to look for different strings all within the one expression, so you would only need to run it once to get all those alternatives removed. You can extend the regex by adding more pipe characters and other strings to search for.

Many Many thanks. I’ve managed to remove a few hundred bothersome lines from a few hundred srt files. Much faster than doing it one by one.

I DO appreciate it.

Steve Wilson

OK. Many thanks again. And I DID read that documentation. It explained a lot, but I didn’t see an answer to this:
I’ve got the following regex.

It works, but since the list of lines I’d like to remove grows, for the sake of simplicity I’d like to use this regex - it has the same expressions but the lines are separate. And reason that wouldn’t work?

That way I could easily scan to see if a line already existed and if not just put it in before the last line followed by a macro for \E .|.\Q

Thanks

Terry R

The following regex will get every one of those lines and it doesn’t care about the case of the character.

So the search is an ‘insensitive’ search, it doesn’t care whether it’s an a or an A. So first off that would save you looking for ‘WWW.’ and ‘www.’ with 2 sub expressions.

You see, there isn’t a need to type every single line you need to search for individually. If you tried you would quickly find you exceeded the limit of the regex allowed. My example identifies a complete line so long as it has the characters defined within each sub expression. They are shown between the ‘|’ characters.

As a couple of the lines are very similar to possible dialogue I’ve made the sub expression look for 2 words with ‘something’ between them. I don’t care what the ‘something’ is, only that the 2 words appear on the same line. This may also be something you wish to try.

The only issue with my example is that it will NOT grab the very last line if that is one of the lines you want. That’s because the last line doesn’t finish on a ‘\R’. I don’t think that would be a problem though, these ‘advertising’ lines would generally be in the first 100 or so lines of each subtitle file I think.

The last 3 tests (advertise your, \.com and million dollar) might potentially occur within dialogue, so you may want to expand on those, but you still should not need to include the WHOLE line.

As to why you expression didn’t work, I found it hard to read, far too much text. I just found it easier to do an example for you, maybe also because I think you are trying too hard to identify the lines. Regex is all about trying to bunch groups/strings of characters into neat buckets, that’s where it’s power lies. In your case you’re removing most of that power and trying to search for each unique line individually.

Hi, @steve-wilson, @terry-r and All,

Indeed, you can use separated lines if you include the (?x) modifier, which enables the free-spacing regex mode !

So, copy/paste the search regex, below, in the Find what: zone, with, of course the two options Regular expression and Wrap around ticked

Notes :

The \R syntax does not work in Free-spacing mode. So, you must write \r\n ( or \n if Unix files )
In Free-spacing mode :
- The # is the comment-line symbol. To use it, literally, simply write \#
- The space character is not taken in account. To use it, literally, simply write \x20 or [ ]
However, when using the \Q.......\E syntax, either, the # and the space symbols are searched, as literals !

So, your multi-lines search regex could be, as below :

(?x)
(?-is)
^(
.*\Q<font color="#ffff00">Sync by honeybunny - corrected by chamallow35</font>\E.*|
.*\Q<font color="#ffff00">www.Addic7ed.Com</font>\E.*|

)\r\n

Remarks :

The entire search selection must not exceed 2,046 characters
Unfortunately, the multi-lines replacement is NOT allowed, with our N++ regex engine !

Et voilà !

OK. I’ve read all the help files and understand a lot more, but I’m finding that a lot of the subtitles I’ve edited are missing lines. For instance, the line:
Help other users to choose the best subtitles
might be in the subtitle and the regex would find it and remove it. But in some of the subtitles, that line is
Help other users to choose the best subtitles
That leading empty space is stopping the regex from catching the line. And of course, that’s just one of the lines that it happens to. I’ve tried changing the line in the regex to .\QHelp other users to choose the best subtitles\E.|, but that doesn’t seem to have any effect. I’ve tried
.Help other users to choose the best subtitles| and .?Help other users to choose the best subtitles| , and neither of those seem to help either. I don’t have any idea what I’m missing. I just want to remove any line in the subtitle that contains Help other users to choose the best subtitles . I don’t care what (if anything) precedes it.

Steve Wilson105

OK, I understand a little better what is happening. I think. If I run a regex on a subtitle file containing 100 lines, single lines of text that are in the regex ARE removed. But sections of the subtitle that have 2 consecutive lines of text listed in the regex would only have the first line removed and a space would be prefixed to the next line. If I run the regex a second time, the second line WOULD be removed. If there were a third line that was listed in the regex (a rare occurrence), that third line would have TWO spaces prefixed. Running the regex a third time would catch that line. Except in cases of there being multiple consecutive lines at the very end of the file. In that case the line just doesn’t get removed no matter how many times I run the regex.

It’s much better than doing this all by hand though, so thanks again.

Steve Wilson105

It works flawlessly. If I run this regex on a directory of files and some of the files have consecutive lines listed for removal in the regex, I’ll get a message at the end like “Replace in Files: 26 occurrences replaced”. If I run the regex until it says “Replace in Files: 0 occurrences replaced”, all of the lines (including the multiple consecutive lines) will have been replaced. Except - occasionally there will be multiple consecutive lines at the very end of the subtitle I’m editing. In those instances, the very last line won’t have been removed. I can solve that fairly simply by loading every subtitle into NP++ and just making sure that there’s a blank line (simply a CR/FL) for the last line. I’ve tried to create a regex to do just that, but they aren’t working. It’s not a huge deal - this is MUCH better and I’m very appreciative, but if what I’m looking for is a trivial thing and anyone has suggestions they’d be very welcome.

As always, thanks very much
