  • First of all operate on refs, don't do copies like my %hash = %{shift()}; just take $h_ref=shift

  • then allow the recursion to accept all ref types not only hashes

  • this seems pretty redundant:

    if (scalar( @{$hash{$key}} ) > 0) { foreach my $list_element (@{$hash{$key}}) {

  • I'd use if/elsif/else clauses if I were you for different types

  • you should handle unexpected types ( like objects) and warn

  • This recent post is an incomplete example only for HoHs, but pretty short.

  • why are you limiting yourself to a regex at the leaves? Better pass and execute a coderef to have a generic solution.

But I'm pretty sure you are reinventing the wheel, better search the archives or CPAN. (Maybe Data::Diver or Data::Walker already do what you want.)
