Im having troubles getting this expression to work. The bolded part of the expression below needs to match anything which I thought a period was used for but its not working out.

(\d+|\d+\s+)-([.*]).([wW][mM][aA])|([mM][pP][3])

btw, im trying to match strings like:

12-mysong.wma
12 - my song.mp3
1 -my-song's.wma

thanks,
josh
 
You shouldn't have the '.*' in the square brackets. Also . and - are special characters so you need the backslash before them to use them normally try.

Code: 
((\d+)|(\d+\s+))\-(.*)\.(([wW][mM][aA])|([mM][pP][3]))

thanks! this works nicely but i had one question. When I tested it at regexlib.com and i look at the match I see 12 and wma in there twice and a value for each space before and after the '-'.

I tested using: 12- my song's.wma

thanks again

ahh nevermind i fixed it, once i figured out grouping ahah This is what I did to get it to group how i want.
Code: 
((\d+|\d+\s+)-(.*).([wW][mM][aA])|([mM][pP][3]))
