I have a function that grabs an XML document and transforms it according to an XSL document. It then places the result into a div with the id laneconfigdisplay
http://api.jquery.com/change/
change does only work on input form elements.
you could just trigger a function after your XML / XSL transformation or make a listener:
var html = $('#laneconfigdisplay').html()
setInterval(function(){ if($('#laneconfigdisplay').html() != html){ alert('woo'); html = $('#laneconfigdisplay').html() } }, 10000) //checks your content box all 10 seconds and triggers alert when content has changed...
