What did you try?
What should be a positive result?
Thanks for answer
A positive result should make the same work than eliminated (old) function...
But... Finally (sorry for my ignorance) I can obtain positive results!!!
The error (I think) was in explanation about work over "Replace with regular expression", using this function, with "script line" explained, I never can obtain positives results, but I begin to make tests, and finally obtain the result positive.
Instead of "Replace with regular expression" I change this for "Format Value"
and in "Format Value" yes, I apply the "script line" (Please, look picture).
And I can obtain the wanted (for me) results.
P.D.: My version of Mp3tag is 2.49 obviously, but I don't know like update "number version" in my profile.
