I want to be able to get the value by just sending my @return = &sub('Root->PersonA->Pets'); to a sub routine

Isn't that what findnodes does? 

use strict;
use warnings;

use XML::Simple qw( XMLout );
use XML::LibXML qw( );


my $perl_datastructure = {
        Root    =>    
                {    
                'PersonA'    => {
                    Pets    =>
                        [qw(
                            PetA
                            PetB
                        )],
                },
                'PersonB' =>
                [
                    {
                        Pets    => 'PetAA',
                    },
                    {
                        Pets    => 'PetBB',
                    },
                ],
            },
};
    
my $xml = XMLout($perl_datastructure, NoAttr => 1, KeepRoot => 1);

my $parser = XML::LibXML->new();
my $doc    = $parser->parse_string($xml);
my $root   = $doc->documentElement();

print $_->textContent(), "\n"
    for $root->findnodes('/Root/PersonA/Pets');

print("--\n");

print $_->textContent(), "\n"
    for $root->findnodes('/Root/PersonB/Pets');
