Ok, so I've tried searching and reading faq to find the solution to this thing, but failed, unfortunately. What I need is this, basically:

Etude Op.10, No.11 In E-Flat Major - Allegretto

switched to

Etude No.11 In E-Flat Major - Allegretto, Op.10

trouble is, there are 24 etudes (e.g. tagged No.1, No.2, No.3, etc.) and I've no idea how to include fields like No._number_. I hope it makes sense 🙂

You may create an action using a regular expression to divide the title string into parts and put the parts together into new sequence:

_Actiontype 5:_ **Format tag field**  
_Field:_ **TITLE**  
_Formatstring:_ **$regexp(%title%,'^(.+?)÷(Op.\d+),÷(No.\d+)÷(.+?)$','$1÷$3÷$4,÷$2')**

... or ...

_Actiontype 4:_ **Replace with regular expression**  
_Field:_ **TITLE**  
_Regular expression:_ **^(.+?)÷(Op.\d+),÷(No.\d+)÷(.+?)$**  
_Replace matches with:_ **$1÷$3÷$4,÷$2**

[\_] Case sensitive comparison

_Note: Replace one special ÷ character with one space character._

 

Input string:  
**'Etude Op.10, No.11 In E-Flat Major - Allegretto'**  
Result string:  
**'Etude No.11 In E-Flat Major - Allegretto, Op.10'**

Thank you very much! (I also needed that). 🙂  
I'll give that a try today.  
I'll also try to learn how to do this kind of stuff.  
Looks very powerful!
