このデータダンプの構造を想定しGeo::Coder::Google
ます --- dd $location;
。

呼び出しの例:
my $long_name = &get_field_for_location("long_name", $location);
次のサブルーチンは最初のものを返しますlong_name
(この例では --- type=route):
sub get_field_for_location($$) {
my $field = shift;
my $location = shift;
my $address = $location->{address_components};
return $_->{$field} for @$address;
}
別のタイプのにアクセスするlong_name
には? つまり、このサブルーチンを変更し$field
て、特定のタイプのエントリにアクセスするにはどうすればよいでしょうか?
