in reply to Acolyte needs regex help

I've found that when writing complex regexs it helps to use /x and to say exactly what you want. This may be slightly incorrect, I don't have a perl intrepeter to check the syntax of everything with, nor do I have any of my regex refrences, since I'm at work, but here it is:

/ (\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}) # IP Address \s+ (\S+) # ident user \s+ (\S+) # auth user \s+ \[ # Square brace ([^\]]+) # date \s # space ([^\]]+) # time zone \] # The closing square brace \s+ " # Opening quote ((?:[^\\] | # method \\.)+) \s ((?:[^\\] | # url \\.)+) \s ((?:[^\\] | # protocol \\.)+) " # Closing quote \s+ (\d+) # status \s+ (\d+) # bytes \s+ " ((?:[^\\] | # refer \\.)+) " \s+ " (?:[^\\] | # platform \\.)+ \s (?:[^\\] | # extended info \\.)+ " /x
Good luck. I'm not sure you really want a regex, other people have given pretty good ideas. I just figured I could throw in a more complete regex. It's probably a lot more sparce than necessary.
