Listen to changes within a DIV and act accordingly

You can opt to create your own custom events so you’ll still have a clear separation of logic.

Bind to a custom event:

$('#laneconfigdisplay').bind('contentchanged', function() {
  // do something after the div content has changed
  alert('woo');
});

In your function that updates the div:

// all logic for grabbing xml and updating the div here ..
// and then send a message/event that we have updated the div
$('#laneconfigdisplay').trigger('contentchanged'); // this will call the function above
