Here's how to convert dynarex records into a hash e.g.



require 'rexml/document'

include REXML



xml =<



  

    Bonsaiasd

    Oakdf

    Sycamoreddf

    Mapleeer

    Pineiuh

    Bonsaivrf

    Hawthornwet

  



XML



doc = Document.new(xml)



class REXML::Document



  def records_to_h

    XPath.match(self.root, 'records/*').map do |row|

      XPath.match(row, '*').inject({}) do |r,node|

        r[node.name.to_s.to_sym] = node.text.to_s

        r

      end

    end

  end



end



tree = doc.records_to_h



#=> [{:name=>"Bonsai", :origin=>"asd"}, {:name=>"Oak", :origin=>"df"}, {:name=>"Sycamore", :origin=>"ddf"}, {:name=>"Maple", :origin=>"eer"}, {:name=>"Pine", :origin=>"iuh"}, {:name=>"Bonsai", :origin=>"vrf"}, {:name=>"Hawthorn", :origin=>"wet"}]



tree[0][:name]   #=> "Bonsai"

tree[0][:origin] #=> "asd"
