title: Eclipse doesn't recognize XML
body: <p>I'm using the PHP Eclipse.
  When a XML file is opened, Eclipse doesn't seem to recognize the xml, meaning that all looks black.
  When opened the XML file like "open with" and point to eclipse, it works fine.</p>
  
  <p>What setting can be set to use that automatically so that eclipse recognizes it all the time?</p>
  
  <p>Same goes for HTML files actually.</p>
