loop() over word in string

Is there any way to in Export script to get $loop('aaa bbb ccc') to loop over the words of the string? Some trick with a variable perhaps, letting the inner code access the current word by $get(var)?

Beside the fact, that I do not know to do something like that, within the current version of Mp3tag 2.48d ... what should be the practical purpose? Please elaborate.


I have a custom field containing sub-values that are codes used across many tracks and I wish to Export a report listing the codes and IDing the tracks that used each.
