body: <p>I stuck with following constellation:</p>
  
  <p><a href="http://jsbin.com/apijo4/11/edit" rel="nofollow">JSBIN Example</a></p>
  
  <p>I want a click function for Check Availibility that does a jquery ajax with a given url (i.e. <a href="http://kiris-alinda.de/temp/verify.php" rel="nofollow">http://kiris-alinda.de/temp/verify.php</a>) checks if the attribute @ges has a value (ie ges="1234") or not (ie ges="") and finally alerts "true" or "false"</p>
  
  <p>XML Response with true: <a href="http://kiris-alinda.de/temp/verify_true.php" rel="nofollow">http://kiris-alinda.de/temp/verify_true.php</a>
  XML Response with false: <a href="http://kiris-alinda.de/temp/verify_false.php" rel="nofollow">http://kiris-alinda.de/temp/verify_false.php</a></p>
  
  <p>Thanks a lot in advance for your feedback and an interesting discussion...</p>
