title: XML => HTML with Hpricot and Rails
body: <p>I have never worked with web services and rails, and obviously this is something I need to learn.
  I have chosen to use hpricot because it looks great.
  Anyway, _why's been nice enough to provide the following example on the <a href="http://code.whytheluckystiff.net/hpricot/" rel="nofollow noreferrer">hpricot website</a>:</p>
  
  <pre><code> #!ruby
   require 'hpricot'
   require 'open-uri'
   # load the RedHanded home page
   doc = Hpricot(open("http://redhanded.hobix.com/index.html"))
   # change the CSS class on links
   (doc/"span.entryPermalink").set("class", "newLinks")
   # remove the sidebar
   (doc/"#sidebar").remove
   # print the altered HTML
   puts doc
  </code></pre>
  
  <p>Which looks simple, elegant, and easy peasey.
  Works great in Ruby, but my question is: How do I break this up in rails?</p>
  
  <p>I experimented with adding this all to a single controller, but couldn't think of the best way to call it in a view.</p>
  
  <p>So if you were parsing an XML file from a web API and printing it in nice clean HTML with Hpricot, how would you break up the activity over the models, views, and controllers, and what would you put where?</p>
