Brackets HELP

I have a bunch of music MP3 files in a folder. Some of them have their title tag set as, for example:
Back Up (Feat. xx) (Album Version)

I want to create an action that will define, if title tag has two pairs of round brackets "()", the second pair should be replaced with square ones "[]"

Back Up (Feat. xx) [Album Version]

Is it possible to create such action (expression) ?

create an action for regular exp.
Reg exp: (.+([^(]+)[^)]+)(([^(]+))$
replace with: $1 [$2]

im on my phone so test this on a single file first. Any problems please report back.

Action: Format value
Field: TITLE
Formatstring: $regexp(%TITLE%,'^([^(]+?)\s(([^(]+?))\s(([^(]+?))$','$1 ($2) [$3]')



TITLE MATCHES "^([^(]+?)\s\(([^(]+?)\)\s\(([^(]+?)\)$"

Other approach:

Begin Action Group Test_2011#20111226.Test.Round.Square.Brackets

Action #1
Actiontype 7: Import tag fields (guess values)
Source format __: %TITLE%
Guessing pattern: %TEMP1%÷(%TEMP2%)÷(%TEMP3%)

Action #2
Actiontype 5: Format value
Field ______: TITLE
Formatstring: %TEMP1%'÷('%TEMP2%')÷['%TEMP3%']'

Action #3
Actiontype 9: Remove fields
Fields to remove (semicolon separated): TEMP1;TEMP2;TEMP3

Note: Replace each special ÷ character with one space character.
End Action Group Test_2011#20111226.Test.Round.Square.Brackets (3 Actions)


Thanks a lot for your help, guys! This is exactly what I wanted to see :smiley:
