How to add a blank space and a word before every comma in some meta tags in every html file of a folder?

Hi, @ramanand-jhingade, @peterjones and All,

I fully support what you said to @ramanand-jhingade. However, I considered that my previous post could be worth to, as it gave, from the same generic regex S/R adapted to mono-lines search, described below, two different solutions for two different goals !

SEARCH (?-s)(?-i:BSR|(?!\A)\G).*?\K(?-i:FR)

REPLACE RR

where :

BSR is the Begin Search-region Regex expression to search BEFORE any FR string located in current line
FR is the Find Regex expression, which may be present once or several times in current line
RR is the Replace Regex expression, which replaces any FR expression found in current line

To @ramanand-jhingade :

The (?-i:This is a Text) syntax is a non-capturing group which searches for the exact string This is a Text
The (?i:This is a Text) syntax is a non-capturing group which searches for the string This is a Text whatever its case. For instance, this regex may find any of these expressions :
- This is a Text
- this is a text
- This Is A Text
- tHIs iS a teXT
- THIS IS A TEXT
Similarly, the (?-i)(This is a Text) syntax is a capturing group which searches for the exact string This is a Text
The (?i)(This is a Text) syntax is a capturing group which searches for the string This is a Text whatever its case. For instance, this regex may find any of these expressions :
- this is A TEXT
- THIS IS a text
- ThIs Is A TeXt

You also said :

g searches for a string repeatedly

Not exactly ! We’re are speaking about the \G assertion ( i.e. a condition ) which is TRUE only if the present match IMMEDIATELY follows the previous match !. For instance, let’s imagine the regex \Ga against the text, below, in a new tab

aaaaaabaaaaaaa
aaaaaabaaaaaaa

Move the cursor at the very beginning ( Ctrl + Home)
Search \Ga
Hit repeatedly on the Find Next button

=> As you can see, it will match any a letter and stop when meeting the b letter. Logical, as the next a char, so the future match, does not immediately follows the previous a letter

Now, move the caret right after the b letter. Again, any a letter is matched but note that it stops after the last char of the first line. Again, this behaviour is logical as, between the last a and the next a, there are the two Windows line-break chars ( CR and LF ). So, the two matches are not consecutive !
And, if you move the caret at beginning of the second line, again, the regex engine will match any a letter till the b letter !

I must admit that the \G assertion, even when explained, is not easy to handle ! At least, much less than the usual ^ and $ assertions which match the zero-length locations Beginning and End of current line !

But modifiers, non-capturing and capturing groups are well explained in most of regex tutorials ! So, no matter, you need to "read this fucking manual" !!

You will probably be disappointed by your first attempts but you will progress ! No doubt about it !

@guy038 You are talking of what is available here: Notepad User Manual right?

Yes. Specifically, as I posted earlier:

Read the official NPP Searching / Regex docs and the forum’s Regular Expression FAQ.

Hi, @ramanand-jhingade

Yes and more precisely :

https://npp-user-manual.org/docs/searching/ about the general concept of searching
https://npp-user-manual.org/docs/searching/#regular-expressions about regular expressions

A valuable site (and the reference !) is that one, too ( not especially devoted to the Boost regex library, used within N++ ) :

https://www.regular-expressions.info/

And begin with https://www.regular-expressions.info/quickstart.html

Of course, you need two weeks, minimum, to feel at ease with simple goals and, let’s say, three months to become fluent to regex syntaxes in order to modify 90 % texts as you want to, about. For the remaining 10 % you’re welcome and we’ll probably find out a suitable solution !

Note that, with the knowledge of basic regexes syntax, the provided solutions should enlighten you much better than at present, without the necessary background !

@guy038 I was able to do what I wanted by using this Regex in the “Find All” field: (?-s)(?-i:<META\x20|(?!\A)\G).*?\Kcure and this cure\x20for in the “Replace in Files” field. Thanks for the idea. Now, a lot of people will find this page through search engines, so just for their convenience and information please do let us know how to search for more than one string of characters and add a word with a space to the end of that string but where the search is limited to the Meta tags (it should not search the rest of the file)

REPLACE ALL $0\x20for
did not work for me!

Reza Saputra

How about this bro?

Ramanand Jhingade

@Reza-Saputra I already searched for each word individually and replaced each with the code I posted for searching for the word, “cure” which was originally given by @guy038 that is (?-s)(?-i:<META\x20|(?!\A)\G).*?\Kcure and this cure\x20for
However, I can tell you that h finds one horizontal whitespace character: tab or Unicode space separator that is it!

Hello, @ramanand-jhingade,

You said :

Well, from the two parts of this previous post and from what I specifically wrote to @peterjones, here, you should had guessed how to do it !

Indeed, from the generic regex :

SEARCH (?-s)(?-i:BSR|(?!\A)\G).*?\K(?-i:FR)

REPLACE RR

where :

BSR is the Begin Search-region Regex expression to search BEFORE any FR string located in current line
FR is the Find Regex expression, which may be present once or several times in current line
RR is the Replace Regex expression, which replaces any FR expression found in current line

we can build up the suitable regex in order to look for, let’s say, 4 different words Word_1, Word_2, Word_3 and Word_4, in meta tags only, written in a single line and add, after each of them, the word WORD !

BSR ( Begin Search-region Regex ) = <META\x20
FR ( Find Regex ) = Word_1|Word_2|word_3|Word_4
RR ( Replace Regex ) = $0\x20WORD

leading to the right regex S/R :

SEARCH (?-s)(?-i:<META\x20|(?!\A)\G).*?\K(?-i:Word_1|Word_2|word_3|Word_4)

REPLACE $0\x20WORD

Now, you said :

SEARCH (?-s)(?-i:<META\x20|(?!\A)\G).*?\K(?-i:Homeopathic (treatment|doctor|clinic|specialist)|Homeopathy)

REPLACE $0\x20for

did not work for me!

Well, may be try this one :

REPLACE $0\x20for

If it does not work either, just send me your file by e-mail. Refer to this post, to get my temporary e-mail address !

@guy038 I already searched for each word individually and replaced each with the code you posted here first to search for the META tag and comma. I used it to search for the word, “Homeopathy”, with this RegEx: (?-s)(?-i:<META\x20|(?!\A)\G).*?\KHomeopathy and replaced it with this: Homeopathy\x20for so I will not bother you again.
I am glad you replied - I think you realised that doing this is was beyond my present abilities and comprehension!
