Remove everything outside of string including string

Scott Sumner

Nice regex simplification, although I would leave in the ?1 in the replace part so that the extra line-ending isn’t added. :-D
And good point about the *nix line endings–sure would be nice if there was a syntax for simply a “line-ending” and it would do the right thing, but I understand and appreciate why you can use \R in the Find what zone but not in the Replace with zone.

@colonialboy

Rather than trying to select (for deletion) text that isn’t what you want to have, I like the technique discussed here which provides a method to copy out the text you are interested in (although it takes an additional plugin+script to do it).

Thanks to @Scott Sumner, and @guy038 for your great answers. Just to push this a little further: my ultimate aim is to put all this info into a spreadsheet. My data looks something like this:

Source’Text

And I am looking for locations in book titles - in this case each line is a book titie and each location is contained within <Word></Word>.
I would like to preserve the line breaks even when some lines don’t contain <Word>. Also if a line contains two or more instances of <Word></Word> , then I would like to place a tab between them for translating it to another column in a spreadsheet. Something like the following:

Resultant

Many thanks again,

colonialboy

*apologies, i’m not sure how to show images inline.

Or at the very least to preserve the line breaks would be fine

Here’s how I would attack your revised need (aside from advising you to experiment on your own with the solutions originally provided…so you learn)–it is just a simplification of the original solution:

Find-what zone: (?:.*?<Word>(.+?)</Word>)|.+
Replace-with zone: ?1\1\t
Post-replace action: Edit (menu) -> Blank Operations -> Trim Trailing Space

The only real difference between this and the earlier is the removal of the leading (?s) from the FW part (to keep line-breaks intact), and the substitution of \t for \r\n in the RW part (to put tab characters in between “Words” occurring on the same line). Putting the tab character in results in a trailing tab character on each line with one or more "Word"s, which the “Trim Trailing Space” action removes.

BTW, inline images may be done as follows:

thank you again @Scott Sumner. I will for sure learn from this and also I hope it provides others too with some help. This is particularly helpful for those that work with “Named entity recognition”!

For convenience here are the two images previously link. @Scott Sumner was able to provide the conversion from this:
Source Text

to this:

Hello @colonialboy, @scott-sumner, and All

UPDATE : Please, do not take in account the S/R explained in this post and see my next post :-)

Ah, OK ! Now, I clearly see the goal :-))

So you could use the following S/R regex :

SEARCH (?-is).*?<Word>(.*?)</Word>(?=.*<Word>)|.*?<Word>(.*?)</Word>.*\R?|.*\R?

REPLACE \1\2?1\t:\r\n

Then, after a click on the Replace All button, your source text, below :

Lorem <Word>ipsum</Word> dolor sit amet, consectetuer <Word>adipiscing</Word> elit.
Aenean<Word>comodo</Word> ligura eget dolor.
Aenean massa.
Cum sociis <Word>natoque</Word>penatibus et magnis<Word>dis</Word>parturient<Word>montes</Word> nascetur ridiculus mus.
Dinec quam felis <Word>ultricies</Word> nec, pellentesque eu, pretium quis, sem.
Nulla consequat massa quis enim.
Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu.
In enim justo, <Word>rhoncus</Word> ut, imperdiet a, venetatis vitae, justo.
Nulam dictum felis eu pede mollis pretium. Integer tincidunt.
Cras dapibus.
Vivamus elementum <Word>semper</Word> <Word>nisi</Word>
Aenean vulputate eleifend tellus.
Aenean leo ligula, porttitor eu, consequat vitae,<Word>eleifend</Word> ac, enim.
Aliquam lorem ante, <Word>dapibus</Word> in, viverra quis, feugiat a, tellus.

will be changed, at once, into :

ipsum	adipiscing
comodo

natoque	dis	montes
ultricies


rhoncus


semper	nisi

eleifend
dapibus

Nice, isn’t it ?

Notes :

To begin, the (?-is) modifiers ensure that :
- The dot ( . ) meta-character will match standard characters, only
- The search will be processed, in a non-insensitive way. So, the string <WORD>, for instance, would not be considered as a tag !
Then the search regex is made of three alternatives :
- The first part .*?<Word>(.*?)</Word>(?=.*<Word>) looks for anything, even nothing, followed by a <Word>(...)</Word> block ( with its contents, possibly null, stored in group 1 ) if, further on, an other tag <Word> can be found, on the same line
- The second part .*?<Word>(.*?)</Word>.*\R? looks for anything, even nothing, followed by a <Word>(...)</Word> block ( with its contents,possibly null, stored in group 2 ) without any other tag <Word>, further on, in the same line
- The last part .*\R? looks for any kind of line, even empty, as this line does not match the first nor the second alternative
In replacement :
- First, the groups 1 and 2, standing for the range of chars between the two tags <Word> and </Word>, and which are mutually exclusive, are just rewritten ( These two groups cannot be non null, at the same time ! )
- Then, if group 1 exits, we write a tabulation character. In all other cases , we do not rewrite any text but simply write a line break ( \r\n ) ( or \n for Unix files ).
- Note that the full syntax, of this conditional replacement, is (?1\t:\r\n), with the colon standing for the limit between the case THEN ( when group1 exists ) and the case ELSE !

Remarks :

Any line, even empty, which does not contain any block <Word>(...)</Word> block, is simply replaced with a line break
Any empty block <Word></Word> is replaced with :
- A tabulation character, if other blocks <Word>...</Word> exist, on the same line
- A line break, if no other block <Word>...</Word> exist, on the same line

Best Regards,

P.S. :

Why, can you simply use the symbols < and > to delimit the ranges of characters to keep ? Of course, this implies that these characters are not part of your initial text !

Thus, the search regex would become (?-s).*?<(.*?)>(?=.*<)|.*?<(.*?)>.*\R?|.*\R?. This should work, although not tested yet !

I reserve downvoting for rudeness, but isn’t this solution way more complicated than it needs to be? The earlier solution proposed seemed to work (I guess) and it was accepted by the OP. So what’s the point in coming up with a more complicated Reg. Exp. solution? What do I miss?

guy038

Hello @colonialboy, @scott-sumner, @alan-kilborn and All

Alan, you’re a thousand right, on that matter. I didn’t even try the Scott’s regex and I wrongly presumed that lines without any <Word>...</Word> were not replaced by a simple line-break !

So, I apologize and, of course, the Scott regex is must more elegant, despite of the supplementary but easy trimming operation !

Cheers,

@guy038 , @Alan-Kilborn :

I agree that unless a poster specifically says “I must have ‘____’ functionality in ONE (regex) operation” , then good multi-step solutions are perfectly viable. Especially if it keeps a regex step much more readable. Some might argue that if they have to do a bunch of individual steps constantly, it gets annoying–to those I’d say that is what the macro recording and playback feature is for. :-)

Side note: If the trim command I used earlier also does tab characters (and it does), shouldn’t it be called “Trim Trailing Whitespace”?

@guy038

I’m guessing you don’t check it very often (hence this posting), but I just sent you an email (to your gmail account) regarding this thread with a “new” technique in it; if it works out as an approach (let me know what you think), we’ll share it here.
