I want to achieve a conditional guess.

source tag %album% needs to be interpreted as 2 tags %album% (%setsubtitle%). I.e. Deep Purple In Rock (Anniversary Edition) would be split in Deep Purple in Rock and Anniversary Edition. Executing 2nd time the script shouldn't do a new split otherwise the 2nd tag will be overwritten.

I tried

```
$if(%setsubtitle%,%%album%% (%%setsubtitle%%),%%dummy%%)

```

but it didn't work.

Maybe what I want could be done using temporary tags but I have the feeling conditional guess is feasible. Probably I don't use the correct syntax.

Thank you.

Feelings can be deceiving - but bad syntax is always right - it simply does not work.

A first help can be to set the Mp3tag Filter [F3] using this expression:

**"%ALBUM%" MATCHES "^.+? \(.+?\)$"**

This reduces the list of files to show only possible candidates.

You can use an action ...

Begin Action Group **Test 2011#20110110.VK** 

Action #1  
_Actiontype 7:_ **Import tag fields (guess values)**  
_Source format:_ **%ALBUM%**  
_Guessing pattern:_ **%ALBUM% (%SETSUBTITLE%)**

 

End Action Group **Test 2011#20110110.VK** (1 Action)

You can use two actions "Format value" ...

  **SETSUBTITLE \<== $if(%SETSUBTITLE%,%SETSUBTITLE%,$regexp(%ALBUM%,'^(.+?)\s\((.+?)\)$','$2')) ALBUM \<== $regexp(%ALBUM%,'^(.+?)\s\((.+?)\)$','$1')**
