mx.utils.IXMLNotifiable

This interface defines the definition of the listener for XML and XMLList objects that are watched using mx.utils.XMLNotifier. The definition is

function xmlNotification(currentTarget:Object, type:String, target:Object, value:Object, detail:Object):void;

It appears the the listener that calls xmlNotification bubbles up the event from the XML object (node, attribute or text) up the XML hierarchy until it reaches the XML object that registered the listener.

Description:

function xmlNotification(currentTarget:Object, type:String, target:Object, value:Object, detail:Object):void {
  // current target appears to be the object that registered the watcher, but don't quote me on that.
  // target appears to be XML object that is being acted upon.
  switch(type) {
     case "attributeAdded":
        // name of attribute == value
        // value of attribute == detail
     case "attributeChanged":
        // name of attribute == value
        // old value of attribute == detail
     case "attributeRemoved":
        // name of attribute == value
        // value of attribute before removal == detail
     case "nodeAdded":
        // added node == value
     case "nodeChanged":
        // node == value
        // copy of old node == detail
     case "nodeRemoved":
        // removed node == value
     case "textSet":
        // next text == value
        // old text == detail
   }
}
