Hi, is your data originally JSON? If so I would skip turning it into a Perl hash and use a tool for JSON like jq.

On the other hand if you have already got an array of hashrefs like that, I would cut them down to size with map. Something like:

my $families = [{ name => "Flintstone", members => { Dad => { name => 
+"Fred", pet => "Dino" }, Mom => { name => "Wilma" } } }, { name => "R
+ubble", members => { Dad => { name => "Barney", pet => "Hoppy" }, Mom
+ => { name => "Betty" } } }];


# deref the arrayref $families, then transform the list of hashrefs in
+to a new list of
# hashrefs containing just one k=v pair, extracted from the input stru
+cture

my @family_pets = map { {$_->{name} => $_->{members}{Dad}{pet}} } @{ $
+families };

say Dumper \@family_pets;

Output

$VAR1 = [
          {
            'Flintstone' => 'Dino'
          },
          {
            'Rubble' => 'Hoppy'
          }
        ];

Hope this helps!
