title: jquery ajax call to a remote php file failing
body: <p>i've got a foo.php file which retrieves client infomation and generates an xml output with the relevant client info.</p>
  
  <p>i'm trying this ajax call which does not seem to want to work</p>
  
  <p>$.get('<a href="http://www.foo.php" rel="nofollow noreferrer">http://www.foo.php</a>','',function(xml){
      $('samplenode',xml).each(function(i){
          //stuff done here
      }); 
  }, 'xml');</p>
  
  <p>i'm still new to javascript, jquery and ajax, so there might be something really silly that i'm overlooking.  </p>
  
  <p>(i've tried replacing foo.php with a foo.xml file with a copy/paste of a sample output, and that works fine, so it really seems to be a problem with the call to a php file.  and if i go straight to the foo.php file with my browser, the xml is all there and properly formatted, so the problem does not seem to be the php script itself.)</p>
