Re: Problem parsing an error msg with regex

Try this:

$errmsg =~ /^((?:\[.+?\]){3})(.*)/;
[download]

The first three brackets are in $1 and the rest of the string in $2.
If all you want is the last part (after the 3 brackets) just do:

$errmsg =~ /^(?:\[.+?\]){3}(.*)/;
[download]

As a quick breakdown (of the first version, the same is the second but without the brackets around (?:\[.+?\]){3}).

$errmsg =~ /^        # Start of string
             (       # Start match $1
               (?:   # Start group (don't save backreference)
                 \[.+?\]  # Match set of []'s
               ){3}  # End group and repeat 3 times
              )      # End match $1
            (.*)     # Slurp up everything that's left
          /x;        # Done

Great, thanks. This one works in a more general sense since I was restricting the stuff between the brackets a bit. PJ use strict; use warnings; use diagnostics;	[reply]
