I need to replace `_xxx` at the end of any audio format with nothing [every `_` sign stands in this post for mine for a pause, because this forum will does not allow to show multiple pauses]  
` `  
` `  
So for example

`Title Of Song xxx.flac`

becomes

`Title Of Song .flac`

but

`Title Of Songxxx.flac`

stays as

`Title Of Songxxx.flac`

[i.e. lack of pause acting a fail-safe]  
` `  
` `

And also

`Title Of Song 2__xx.mp3`  
`Title Of Song 2___XXX.mp3`

become

`Title Of Song 2__.mp3`  
`Title Of Song 2___.mp3`

but

`Title Of Song 2xx.mp3`  
`Title Of Song 2XXXX.mp3`

stay as

`Title Of Song 2xx.mp3`  
`Title Of Song 2XXXX.mp3`  
` `  
` `  
So how do I do this?

You could try:  
`$regexp('Title Of Song xxx',(.*)\s+xxx,$1)`

I think I should also have precised, that it should work for any titles / filenames, and not just literally for `Title Of Song`  
` `  
` `  
Modifying this Format Value to

> `$regexp(' xxx',(.\*)\s+xxx,$1)

makes the whole `_FILENAME` disappear, leaving only the extension; even when there is no `xxx` present at all in it

This makes no sense at all if you want to modify the filename - as this look in the string " xxx" for at least 1 space character and "xxx" which produces an empty string in `(.*)` and therefore deletes the filename.

So, please, instead of the string constant in your examples (and my reply) use the property variable %\_filename%.

OK, those two variations seem to work as I need it them to do:

> $regexp(%\_FILENAME%,(.\*)\s+xxx,$1)

> $regexp(%\_FILENAME%,(.\*)\s+XXX,$1)

So, thank you
