Working to build a to_hash method for a Nokogiri::XML::Document

gistfile1.rb

# Converting Nokogiri parsed XML to_hash
require 'nokogiri'

module Extensions
  module Document
    def to_hash
      root.to_hash
    end
  end
  
  module Node
    def to_hash(hash={})
      hash[name] = content

      walker = lambda do |parent, child, callback|
        next if child.blank?

        child_hash = {child.name => child.content}

        child.children.each { |c| callback.call(child, c, callback) }
      end

      children.each { |c| walker.call(self, c, walker) }
      hash
    end
  end
end

Nokogiri::XML::Document.send(:include, Extensions::Document)
Nokogiri::XML::Node.send(:include, Extensions::Node)
end
