in thread extact nested values

Hi MCA thanks for the reply but my problem is to print the values of the child elements of the link nodes iteratively and

print $VAR1->{'press-release'}->[0]->{'PromoModuleTwo'}->[0]->{'RightC +oloumn'}->[0]->{'Tabs'}->[0]->{'TabName'}->[0], "\n";
isn't printing anything

    Do you know how to iterate over a perl list?

    As the dumper output shows: The output of $VAR1->{'press-release'}->[0]->{'PromoModuleOne'}->[0]->{'RightColoumn'}->[0]->{'Tabs'}->[1]->{'Links'} is a list ref.

    So the following

    my $list_ref = $VAR1->{'press-release'}->[0]->{'PromoModuleOne'}->[0]- +>{'RightColoumn'}->[0]->{'Tabs'}->[1]->{'Links'}; foreach my $elem (@$list_ref) { print "Element by element", Dumper($elem), "\n"; }
    iterates over the list and you get every element which is by the way also a nested object. But with my solution shown it should be worth of a little transfer to address the child elements in every $elem. If this is not true then you have to learn some basics.

    Best regards
    McA
