in reply to split on the pattern of '),('

Assuming nesting (e.g. (3,(4,5),6)) can't happen, 

my @recs = $recs =~ /
   \G
   \(
   ( (?: [^()"] | "[^"]*" )* )
   \)
   (?: , | \Z )
/xg;

    my $string = "(foo),(bar),(baz)";
my @parts  = split m{ [)] [,] [(] }x, $string;
print "GOT: $_\n" for @parts;

    Instead of m{ [)] [,] [(] }x you could use m{ \) , \( }x ... whichever you think is most readable. Either way, try to avoid the appearance of a million toothpicks standing on end.

      That fails for 
      $str = '(1,"(text),(text)", 123),(2,"(string)", 234),(...)';

        No it doesn't. The string you give contains "),(" three times, and my regex splits it at all three.

        use Test::More tests => 5;

my $string = '(1,"(text),(text)", 123),(2,"(string)", 234),(...)';
my @parts  = split m{ [)] [,] [(] }x, $string;

# Prove that the split worked properly...

# Firstly, joining the parts back with '),(' recreates the original st
+ring.
my $joined = join '),(', @parts;
is($joined, $string);

# Secondly, none of the individual parts contain '),('
unlike($_, qr{\Q),(\E}) for @parts;
