title: How do I use Sinatra to serve XML documents?
body: <p>I have some XML documents that I'd like to server from Sinatra. I did some searching but couldn't find anything specific. 
  I did find the builder gem but I don't want to build the document from scratch.</p>
  
  <p>I tried to do something like this</p>
  
  <pre><code>get '/'
    xml = '&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt; &lt;name&gt;My name&lt;/name&gt; &lt;age&gt;90&lt;/age&gt;'
    body xml
  end
  </code></pre>
  
  <p>but that will add the HTML tags around it. It's probably something really basic I'm missing. Can you point me in the right direction please?</p>
