I have a set of files with YY-MM-DD dates in the file names, but they're really inconsistent: A_39_09_21_morestuff.mp3 39_09_21ABC.mp3 I'd like to parse these values out and write them to the comment field. Been trying to puzzle out $regex(%title%,d{2}_d{2}_d{2}) but that doesn't seem to work for…

I am always a friend of filters - so why don't you filter for %_filename% HAS -xx-xx and then treat the files with Format string: $regexp(%_filename%,.*(\d\d-xx-xx).*,$1) And then you check for files that do not have a comment and the digits %_filename% MATCHES "\d\d.\d\d.\d\d" AND %comment% MI…

Thanks. I think that will help. The files are set up where everyhting is underscored so I want to parse files like Funny_Side_Up_xx-xx-xx_Check_For_Water_Bill.mp3 to {album} - Funny_Side_Up {comment} xx-xx-xx {title} - Check_For_Water_Bill Flying_Hutchinsons_The_39-08-14_Scroll_Of_All_Nations …

[image] mlmp3: field COMMENT expression (%_filename%,.*(\d\d.\d\d.\d\d).*,$1) Could you show what you enter exactly? Because "Expression" is no valid function. It should be: [image] ohrenkino: Format string: $regexp(%_filename%,.*(\d\d.\d\d.\d\d).*,$1)

Here's one: filename - Stars_for_the_Defense_52-xx-xx_First_Song_-_I_Wanna_Be_Happy.mp3 [image] this one works fine of course: filename - Stars_Over_Paradise_41-11-28_Sandra_Leaves_Gordon.mp3 [image] My ultimate goal is to parse the filename before 00-00-00 into album, the 00-00-00 (or 00-xx-x…

AFAIC tell [image] mlmp3: Stars_for_the_Defense_52-xx-xx_First_Song_-_I_Wanna_Be_Happy.mp3 does not have 3 pairs of digits separated by any character but only 2 digits ("52") followed by another string which happens to have something like placeholders in the shape of "-xx-xx". But those x-s…

Right, that's kind of my next problem. At this point I'm wondering if it would be better just to go with a Python program to read the directories and fileglob, but i think MP3Tag is a really capable program and it -almost- seems possible. Thanks for your help, I appreciate it.

I'll try that - thanks for all the help! Marking your answer as solution.

Deleted the previous post as it didn't have a leading 0 but this one does: [image] I want to parse the filename as Part before 00-xx-xx : Album (Famous_Fathers) Part including 00-xx-xx: Comment (41-xx-xx) Part after 00-xx-xx: Title (24_Fathers_In_The_Household) Can I do this in one pass, and i…

I got this regex from stackexchange to find all before a string: /.+?(?=abc)/ (from regex - How can I match "anything up until this sequence of characters" in a regular expression? - Stack Overflow ) but my attempt to implement it to parse Famous_Fathers into ALBUM still returns the whole file nam…

You can not match _xx_xx if your filename includes -xx-xx A working regex for exactly this filename: Famous_Fathers_41-xx-xx_24_Fathers_In_The_Household to get the ALBUM from the _FILENAME would be: $regexp(%_FILENAME%,(.*)_(\d\d-xx-xx)_(.*),$1,1) To get the COMMENT replace $1 with $2 To get t…
