Ok, need a little help here....
First off, anyone know of a good Regular Expression tutorial ? I'd like to learn how to do this myself...
While I dig around for one, would appreciate it if someone could enlighten me as to how I do the followig :
search for x-x and replace with x - x where x is any character
change the string track - artist - title (pres artist2) (mix_name) to track - artist pres artist2 - title (mix_name)
Fun facts about the second one :
'track' and '(mix_name)' are optional
'pres' may be 'feat' or 'vs.' - but all files will have one of the three
I would
greatly appreciate any assistance offered.

Thanks for the help d4n0, but the second one didn't quite work.
Your suggestion resulted in :
when I am looking for :
When I broke the results down into $1 - $2 - $3 - $4 - $5, it does not appear to be seperating the string title (pres artist2) into two compenents.
I checked the help file as you suggested, but apparently I am daft...
Any more suggestions ?

i have no clue why title (pres artist2) is always together
Check the greedyness of the repeats in the parenthesis part. The regular expression^(\d{1,2}\s-\s)?(.)\s-\s(. )\s((.?))(\s(. ?))

it does not work when there is no (mix_name) at the end
Oh yes, you're right! I've changed all repeats to be non-greedy in your regular expression and now it should work for both cases.
^(\d{1,2}\s-\s)?(.?)\s-\s(. ?)\s((.?))(\s(. ))? $1$2 $4 - $3$5
Best regards,

awesome, yes seems to be fine now
You can translate greedyness with "Gierigkeit". Greedy (standard) repeats are eating as much characters as possible - the non-greedy ones (those with the question mark after the repeat character) don't
