title: XML shows up as plain text
body: <p>I retrieve XML from a external provider, and for debugging i usually view it from the browser. Unfortunately the case is that only Internet Explorer is able to render the data as XML. All other browser as Chrome, Safari, Firefox all render it as plain text for some reason.</p>
  
  <p>Can anybody explain why this is the case?</p>
  
  <p>Thanks.</p>
