How to convert a nested hash into XML using Nokogiri

Question

I have many levels of a nested hash like:

 { :foo => \'bar\', :foo1 => { :foo2 => \'bar2\', :foo3 => \'bar3\', :foo4 => { :foo5 => \'bar5\'         


        

Answer 1

How about this?

class Hash
  def to_xml
    map do |k, v|
      text = Hash === v ? v.to_xml : v
      "<%s>%s" % [k, text, k]
    end.join
  end
end

h.to_xml
#=> "barbar2bar3bar5"
