Hello, I have a lot of mp3s in which the title is structured as follows:
```auto
Hootology (Feat. BoriRock & Shaykh Hanif) (Remix) [Prod. By 4th Beats]
```
I would like to use an action to copy the following information from them:
%artists% : BoriRock & Shaykh Hanif
%composer% : 4th Beats
I can do it with tag - tag but not with an action
tag - tag
```auto
ARTISTS
$regexp(%title%,'.*? \(Feat\. (.*?)\).*',$1)
```
```auto
COMPOSER
$regexp(%title%,'.*?\[Prod\. By (.*?)\]',$1)
```
Can you help me with how I can pack this into an action?

The action equivalent to Convert\>Tag-Tag is an action of the type "Format value"
BTW: this information was made available to you already in this thread:
> [@Replace (Prod by XXX) to \[Prod. by XXX\]](https://community.mp3tag.de/t/replace-prod-by-xxx-to-prod-by-xxx/57330/6):
>
> Scripting functions can be used in format strings. So an action of the type "Format value" would be good. Or the Converter\>Tag-Tag. You have not yet mentioned which field you want to modify.

Action from type "[Format Value](https://docs.mp3tag.de/actions/format/)" that looks like this:
the same for COMPOSER with your second regular expression as Format string.

I just noticed another problem.
If the title doesn't have (Feat. xyz) and/or [Prod. By xyz], the whole title is copied. Can this be prevented?

Only if you adjust your regular expression.
A regular expression does not work for every variation.
You can either use several different regular expressions (and Actions) or you can try to fine-tune your existing one. Even this will not work for every thinkable form of TITLE content.

Do you have any idea how to check whether the title includes Feat. and/or Prod.?

Sorry, you have to build your examples and try it by your self, for example with the help of online tools like [regex101.com](https://regex101.com/r/GcmcyN/1).
I would have to do the same.

The easiest way would be to apply filters and then treat only matching files.

that works
```auto
$if($eql($regexp(%title%,'.*? \(Feat\. (.*?)\).*','$1'),%title%),, $regexp(%title%,'.*? \(Feat\. (.*?)\).*','$1'))
```

Please test your functions and regular expressions carefully.
Your above THEN part would at least add a space in front of the extracted part, because of
`,, $regexp`
` ↑ `
Every character counts. 😉
