I am trying to skip a Section if it already Exists (above). However, the following script add a new line "Exists", but doesn't skip the Section. 
use strict;
use warnings;
use 5.010;

my @lists;
my %group;
my $lastGroup;

while (defined(my $line = <DATA>)) {
    next if $line =~ /^access-list .*\bremark\b/;

    given ($line) {
        when (/^access-list/) {
            my @keys = $line =~ /([A-Z]+[-_][A-Z]+)/g;
            push @lists, {groups => \@keys, line => $line};
        }
        when (/object-group\s+(\S+)\s+(\S+)/) {
            $group{$2}{line} = $line;
            $group{$2}{data} = [];
            $lastGroup       = $2;
        }
        default {
            push @{$group{$lastGroup}{data}},   $line;
            push @{$group{$lastGroup}{groups}}, $1
                if $line =~ /^\s+\S+\s+(\S+)$/;
        }
    }
}

for my $list (@lists) {
    print $list->{line};
    printGroups($list->{groups}, %group);
    print "\n";
}


sub printGroups {
    my ($groups, %groupData) = @_;

    for my $group (sort @$groups) {

         ############ Skip if Exists above #####
         print "Exists above\n"    if exists $groupData{$group};
         ############ end Skip            #####

        next if !exists $groupData{$group};

        print $groupData{$group}{line};
        print @{$groupData{$group}{data}} if $groupData{$group}{data};
        printGroups($groupData{$group}{groups}, %groupData)
            if Existss $groupData{$group}{groups};
    }
}
