A hash is not ordered, so you won't be able to have 'each' return the
fields in any particular order.

A solution might be to give each field a name that includes a prefix:

  A_name
  B_address

or

  00_name
  01_address

Then you can sort the set of keys before processing them:

   h.keys.sort.each do |key|
     ...
   end
