    The second example given by ikegami above should work for you , provided you have a defined separator that doesn't conflict with your data.

      But I get the error as,

      Use of uninitialized value in split at santhosh.pl line 27. $VAR1 = [];

      Following is the code I tried

       use strict;
use warnings;
use Data::Dumper;
my $test="[1,2second,3third,fourth]";
my ($list) = $test =~ /\[ ( [^\]] ) \]/x;
my @var = split /,/, $list;

print Dumper \@var;

        There's a slight error in the regex, 
        my ($list) = $test =~ /\[ ( [^\]]+ ) \]/x;
