I am trying to make a similar replacement for music file types. Basically I want all of them to always be lowercase, after using mixed case.
The RegEx I'm using is this:
FIND...: (.AAC)$|(.AIFF)$|(.APE)$|(.CDA)$|(.FLAC)$|(.M4A)$|
(.MP3)$|(.OGG)$|(.WAV)$|(.WMA)$
REPLACE: \L\1\L\2\L\3\L\4\L\5\L\6\L\7\L\8\L\9\L\10
However, this replaces ".flac" by ".flac0" (I'm using Mp3Tag v2.60 - the latest now)
If I remove one of the expressions, making them only 9, it works as intented.
So is this a bug or just a lack of support by MP3Tag for more than 9 replacements on the same Regular Expression?
Suggestion: Maybe it's just a matter of padding the number to two digits (e.g. 09, instead of 9), and always read two digits instead of just one.
Didn't the OP intend to convert the case to lower ...?
What I am still wondering: why do you need that lenghty list of extensions, if you actually want to convert teh case of all extensions to lower?
Isn't there a pattern of (,)(..)$ enough?
Many thanks to you DetlevD!
This line with the pipes makes all the difference. I didn't know I could join several words to be affected by the same regex. I only thought it would allow to join several different reg expressions, not just words. . . But now I know, I discovered this on another google search yesterday. eheheh What a pity I didn't come here earlier. . .
I was focused on solving the problem, and I did it. Now I'm using only 1 or 2 reg ex. What a difference!
I also liked to thank Florian for poiting out the limitation of 9 expressions. I didn't know about it.
Somehow a similar pattern wasn't working in my expression.
In fact, I even experimented it in two text editors I trust (Notepad++ and EmEditor), and the expression worked, but on Mp3Tag it would always UPPERcase the first letter of the file extension, so I quit using the _FILENAME. And then I also realized that the _FILENAME would have to have a specific regex because it may have other text besides the title, something that initially I didn't think about.
So I ended up quitting to change the _FILENAME. I'll leave that to the user and there's an advantage to that: the user may check the difference before and after the change, by comparing the TITLE and the FILENAME.
