get all states for countries and write them to yaml file

require 'open-uri'
require 'yaml'

h={}
(1..267).each do |x|
  open("http://www.couchsurfing.org/get_option_values.html?cpaint_function=get_states_auto&cpaint_argument[]=#{x}") do |f|
    if f.first
      # anybody knows why it doesnt check if the string is empty before it executes the split ???
      # I went through all x which dont work and substitude f.first with 
      # x!=112 and x!=122 and x!=124 and x!= 150 and x!=219 and x!= 240
      # which works. Pretty weird!
      f.first.split('#').collect{|i| i.split('|')}.each do |i|
        h["state_#{i[0]}"]={}
        h["state_#{i[0]}"]["id"] = i[0]
        h["state_#{i[0]}"]["state_id"] = i[1]
        h["state_#{i[0]}"]["country_id"] = x
        puts "country_id: #{x}, state_id: #{i[0]}, state: #{i[1]}"
      end
    end
  end  
end
File.open('states.yml', 'w') do |f|
  f.write(h.to_yaml)
end
