Removing blank nodes recursively from nokogiri object

While parsing xml using Nokogiri it contains blank nodes in parent and childre nodes it looks like this

#<Nokogiri::XML::Text:0x2d02be8 "\n">

and noblanks removes only blank nodes in parent node which become really hard when  recursively fetching nodes.

To remove blank nodes recursively from every children and their children this code will work for you.

    module NokoHacks
      extend ActiveSupport::Concern

      Nokogiri::XML::NodeSet.send :include, NokoHacks
      Nokogiri::XML::Text.send :include, NokoHacks
      Nokogiri::XML::Element.send :include, NokoHacks

      def remove_blank_node
        self.children.each do |node|
          if node.blank?
            node.remove
          end
          if node.children
             node.remove_blank_node
          end
        end
      end
     end

Now apply it the parsed nokogiri object in this code I have also removed namespaces.

xml_obj = Nokogiri::XML(File.open('config/london.xml')).remove_namespaces! do |config|
      config.default_xml.noblanks
    end 

xml_obj.children.remove_blank_node
