Need Help about swap field content

[JoaoBC]

Good morning my friends. Another request for technical assistance.

Imagine a field with two content options, for example "word1" and "word2".
How do I exchange? Where it was "word1" becomes "word2".
Where it was "word2" becomes "word1".
What is this for?
I have a collection of Brazilian songs on the pendrive, where the OBS field says "national" and American songs, where the OBS field says "foreign".
To send a copy of this pendrive to a relative who lives in the USA, I need to reverse it.

Another example: my favorite songs, in the OBS field it says "mine", and the girlfriend's favorites, it says "girlfriend".
To send a copy to the girlfriend, where it says "girlfriend" I will change it to "mine", and where it says "mine" I will change it to "boyfriend".

Thanks in advanced

You could start with the FAQ here:

Actions and batch-operations

How to swap the contents of 2 tag fields? Example how to swap TITLE and ARTIST: Create a new action in an existing action group or make a new action group. Action type: Guess values Source format: %title%~%artist% Guessing pattern: %artist%~%title% Note: The ~ sign is just used to separate the two fields, you could take any other sign that does not appear in your fields, e.g. ¢ or an extended unicode character like ∞ or ∑.

If this does not work for you, please show us a screenshot from a real existing music file
(pressing Alt + T or menu View - Extended Tags)

The problem is to swap content in the same field, not swap the content between 2 different fields.
It could be done using 3 Replace actions:

1. Replace "word1" with "xyxyxyxy"
2. Replace "word2" with "word1"
3. Replace "xyxyxyxy" with "word2"

In that case, one could also try an action of the type "Format value" for that field
Format string: $if($eql(%fieldname%,word1),word2,word1)

A filter should be applied so that really only files with the contents word1 or word2 are treated. Otherwise all other words would be replaced with word1.
