Dear Regex gurus...
I have reached the limit of my regex knowledge, and cannot figure this problem out.
I have titles such as:
```
Song Title (Feat. Guest Artist) (Deejay Mix)
Song Title 2 (Remix version)
Song Title 3 (Feat. Backup Singer)
Song Title 4 (Mega Dub) (Feat. Someone)
```
I'm looking for a regex set that would be able to grab the Featured Artist info (except for the parens) and isolate it in a temporary field so that I could append it to the end of the Track Artist field.
I started with FORMAT VALUE "TEMP1": %TITLE% and FORMAT VALUE "TEMP2": %TITLE%, then Regex TEMP1: ^(.+)((.+))$ -\> $1 and
```
Regex TEMP2: ^(.+)\((.+)\)$ -> $2 (and putting TEMP2 after ARTIST and TEMP1 back into TITLE)
```
but this doesn't check to see if the TEMP2 actually contains "Feat."
The other thing I've been working with is ([Ff]eat[^)]+), but I don't know how to capture this group so that it could go into another field... and it leaves "()" behind since it ignores the opening and closing parentheses.
Any ideas?

I dunno:
Perhaps the regexp approach is not right.
Have you tried "Import Tag field (Guess values)"?
e.g.
Song Title 3 (Feat. Backup Singer)
would look like this:
%title% (Feat. %featartist%)
Or if you copy all of the title data into FEATARTIST (as a temporary field) and then apply the "Guess values" action, it would be:
%dummy% (Feat. %featartist%)
For tracks like
Song Title (Feat. Guest Artist) (Deejay Mix)
I would prefer the copy-first-approach and then use:
%dummy% (Feat. %featartist%) (%dummy%)
Finally you replace all (feat. .\*) with nothing in TITLE.
And then you add the %featartist% to TITLE with format value.

Move FEAT from TITLE to ARTIST and such alike ...

DD... that was amazing! I specifically used the first one you noted in thread 17973, copied here for posterity and reference:
ARTIST
Formatstring: %ARTIST%' feat. '$regexp(%TITLE%,'^(.+?)\s+[[({\<]?(?:ft.?|feat.?|featuring)\s+(.+?)[])}\>]?\s\*((.+?))\s\*$','$2',1)
"Titel (Ft. Artist 2) (Sososo Remix)" -\> "Artist 1 feat. Artist 2"
"Titel Ft. Artist 2 (Sososo Remix)" -\> "Artist 1 feat. Artist 2"
TITLE
Formatstring: $regexp(%TITLE%,'^(.+?)\s+[[({\<]?(?:ft.?|feat.?|featuring)\s+(.+?)[])}\>]?\s\*((.+?))\s\*$','$1 $3',1)
"Titel (ft. Artist 2) (Sososo Remix)" -\> "Titel (Sososo Remix)"
"Titel ft. Artist 2 (Sososo Remix)" -\> "Titel (Sososo Remix)"
I hadn't looked through the .de forums, since I learned French and Spanish in school....
Tausand Dank!

Ok, one new issue.
I'm trying to automatically implement the filter that you mentioned in the previous thread:
```
Filter: "%TITLE%" MATCHES "^.+? \(?ft.+?\)? \(.+?\)$"
```
using an $if function.
My current attempt for the filter and the format string is:
```
$if(%TITLE%" MATCHES "^.+?\((?:[Ff]t.+?|[Ff]eat.+?|[Ff]eaturing.+?)\)\s*\(.+?\)$,%ARTIST%' feat. '$regexp(%TITLE%,'^(.+?)\s+[[({<]?(?:ft\.?|feat\.?|featuring)\s+(.+?)[])}>]?\s*(\(.+?\))\s*$','$2',1),%ARTIST%)
```
I've tested my MATCH function (^ to $) in an online regex tester ([regexpal.com](http://regexpal.com/)), and it appears to work properly.
Test case Titles are:
```
More of You (Feat. Rasul) (Soulmagic Classic Remix)
The Touch (Vocal Mix)
Born Free
Dreaming (Feat. Mr. Bailey)
```
When I test the MATCH function, only the first title highlights.
When I try to run the whole $if function in MP3Tag, though, it would give me this sort of output.
```
ARTIST ~~~~~ TITLE
Alfred Azzetto feat. Rasul ~~~~~ More of You (Soulmagic Classic Remix)
J Nitti feat. The Touch (Vocal Mix) ~~~~~ The Touch (Vocal Mix)
Jay Vegas feat. Born Free ~~~~~ Born Free
Sandy Turnbull feat. Dreaming (Feat. Mr. Bailey) ~~~~~ Dreaming (Feat. Mr. Bailey)
```
Is there an implementation error that I'm not catching?
Danke!

1.
The "Mp3tag Filter [F3]" is a feature of the Mp3tag listview, which allows to _filter the listview_.
The "Mp3tag Filter [F3]" has its own scripting language and operators, see manual.
The Mp3tag scripting language for _Actions_ is different.
Do not apply both scripting languages into one format string for Actions.
1.
If a regular expression in function $regexp() does not match, then the function returns the unchanged input string.
1.
To simulate a 'does not match' filter ...
$if($eql($regexp(Inputtext,RegExpr,RegRepl),Inputtext),DoNothing,DoSomething)
$if($neql($regexp(Inputtext,RegExpr,RegRepl),Inputtext),DoSomething,DoNothing)
... or ...
To simulate a 'does match' filter ...
$if($eql($regexp(Inputtext,RegExpr,),),$regexp(Inputtext,RegExpr,RegRepl),DoNothing)
