You need to let XML::Simple know that subcategory, product and prod_id are arrays, even if you use them only once. Replace your XMLin line with this one and read about KeyAttr and ForceArray in the XML::Simple pod. 
my $xml = XMLin( (join'', <DATA>),  KeyAttr => 1, 'ForceArray' => [qw/
+subcategory product prod_id/]);
