srpid.each do |rpop|
@popa = Array.new
   rpop.each do |key, value|
      if key == "RegionCode"
      @RegionCode = value
      elsif key == "Hostname"
      @Hostname = value

      pop = Hash.new
      pop[@RegionCode] = @Hostname
      #puts pop
end
      @popa.push(pop)
end

i want it to look like this:
[{region => hostname}, {region => hostname}]
