Hi,

I have two reference A and B. Ref B is the part of ref A. I am trying to iterate A and check ref B is the part of ref A. Below I place the code which i tried. I am expecting your suggestion to compare the two reference in perl way.

Thanks

use Data::Dumper;

my $part = {
          'c' => {},
          'func' => []
        };


my $main = {
          'a' => {
         'b' => {
                'c' => {},     ### equals to $part hash reference
                'func' => []
              },
         'func' => [
                 'd',
                 'e'
               ]
           }
        };





walk ($main);


sub walk(){
    my ($item, $path) = @_;
    if (ref $item eq 'ARRAY') {
        foreach (@$item) {
            walk($_, $path);
        }
    ### Need to change the condition/logic here...
    if ($item eq  $main) {
        print "\nExpected data match here ... ", Dumper $part;
    }
    } elsif (ref $item eq 'HASH') {
        foreach (sort keys %$item) {
            push @$path, $_;
            walk($item->{$_}, $path);
            pop @$path;
        }
    }
}
