However, I'm in a position where I can't install Data::Diver (or any other external module for that matter).

Yes, even you can use CPAN! I strongly suggest to take some time to look into e.g. local::lib or maybe App::FatPacker.

Having said that, I've written some custom "diver" type code here and here.
