title: PHP / Wordpress - Loading a remote XML file
body: <p>How can a get a object variable from a remote XML file, for example <a href="http://ws.audioscrobbler.com/2.0/artist/Faithless/events.xml" rel="nofollow">this one</a> ?</p>
  
  <p>In PHP5 it works fine with <strong>simplexml_load_file()</strong>, but I need this to work in PHP 4 also. How can I do that?
  Or is there any built-in WordPress function that can load xml files? I tried using the <a href="http://wphit.com/lookup/files/wp-includesclass-simplepie-php/" rel="nofollow">WP's SimplePie class</a>, but I get a weird object variable (with incorectly named fields etc).</p>
