Subject: where is the each_recursive method defined?

#i'm new  to ruby. i download the machanize gem and install it.
in  machanize.rb , root_node has an each_recursive method,but i can't
fine the definition in docs. who can tell me what to do,thanks in
advance.

def self.extract_all_from(root_node)
    fields = []
    root_node.each_recursive {|node|
      if (node.name.downcase == 'input' and
         %w(text password hidden checkbox radio
int).include?(node.attributes['type'].downcase)) or
         %w(textarea option).include?(node.name.downcase)
        fields << Field.new(node.attributes['name'],
node.attributes['value']) 
      end
    }
    return fields
  end
