Thx for the reply guys.
In a previous version of MP3Tag, whenever i would perform a REGEX on multiple files, the values with "\\" in them would automatically be split over multiple tags. Which, i guess, is the intended behaviour.
In the current version of MP3Tag v2.69 however, the '\\' doesn't seem to split the values over multiple tags. To force "\\" conversion to multiple values, i have to CTRL+S the files individually.
So after REGEX i'm left with what is seen on Extended Tags screenshot.
As you can see its not a visual representation but rather literal one.
Now, if i apply the tags above with your action, the results has some undesired effects:
Action "Format value"
Formatstring: $replace($meta_sep(COMMENT,'~'),'Categories – ',,'~','\\')
White = need attention, it gets CATEGORIES as fieldname
Purple = split values
Grey = original tags
Obviously the desired format would be:
ARTIST LOCATION = American
CATEGORIES = Genius
CATEGORIES = Trumpet
TRACK DECADE = 2010s
Maybe an even better approach? This way B would always the end up with the correct fieldname.
1. Is there a way to target fieldname A
2. Split B and C from the values
3. and then assign B as new fieldname, with C as value
Sorry for being a pain. Still learning here.
