So what if you have a list of countries, where each country has a list of provinces, and each province has a list of cities, and some cities have lists of neighborhoods? But you only need neighborhoods with names beginning with "k" in provinces that begin with "c". This is where I start getting confused and looking for a stiff drink.

    You did exactly what I suggested you don't do. Don't look at the whole. These are the things you actually need to do:

    • Identify if a neighbourhood name starts with 'k'.
    • Get a city's list of neighbourhoods.
    • Get a province's list of cities.
    • Identify if a province's name starts with 'c'.
    • Get a country's list of provinces.
    • Get a list of countries.

    They're all independent. Nothing in there even suggests that you have a nested structure in memory.

    The hard part:

    print("$country_name/$province_name/$city_name/$neighbourhood_name\n") if $neighbourhood_name =~ /^k/i;

      Some days, it's hard to make myself do that. Thank you.
