String manipulation with Regex

Subject: String manipulation with Regex

Hi,

I have been looking around a bit for a way to extract parts of a string using a specific patter. More in details I am writing a program to insert id3 tags based on the file name. Let's say I have the file named: song - someartist - 5 - album.mp3. The user shall then be able to type in a pattern like %s - %a - %t - % b (%s represents songname, %a - artist, %t, tracknumber, and %b - album).

Right now I am trying to solve this with NSScanner but thought it might be easier using NSPredicate or Regex.

Any ideas?

Thanks
