Parsing a RSS Feed

A friend was asking me how they could easily read a RSS feed and display the last x items in their rails project. This was my quick and dirty response.


require 'rss/2.0'
require 'open-uri'

class RssfeedController &lt; ApplicationController

  def index
    feed_url = 'http://www.planetrubyonrails.org/xml/rss'
    output = "<h1>My RSS Reader</h1>" 
    open(feed_url) do |http|
      response = http.read
      result = RSS::Parser.parse(response, false)
      output += "Feed Title: #{result.channel.title}<br />" 
      result.items.each_with_index do |item, i|
        output += "#{i+1}. #{item.title}<br />" if i &lt; 10  
      end  
    end
    render_text output
  end

end

Is there an easier way to do this with another RSS library? I figured that the simplest method would be to just use the standard library that comes with Ruby.
