accessing parent class' methods (AS2) while parsing

[3rdw0rld3r]

Hi,

I have a class with a load() method that loads an xml file. From this method, I want to call another method from the same class, while the xml is being parsed:

class someClass {
...
function load(url:String):Void {
	var myxml = new XML();
	myxml.ignoreWhite = true;
	myxml.onLoad = function(success:Boolean) {
		if (success) {
			var categoryNodes:Array = this.firstChild.childNodes;	
			for (var i = 0; i < categoryNodes.length; i++) {
				var c:Category = addCategory(categoryNodes[i].attributes.label);
			}
		} else {
			trace("There was an error parsing the XML data");
		}
	};
	_xml.load(url);
}

function addCategory(label:String):Category {
	trace("add category called");
	var c:Category = new Category(label);
	_categories.addItem(c);
	return c;
}
}

from my understanding, I should be able to call addCategory() like this, since it's a member method... but it doesn't work. I tried adding _parent to the path, but it doesn't work either, even if I make var myxml a class property.
How do I access this method?

any input would be greatly appreciated.

I've found the solution at flash-coders:

the best way would be to extend the XML class and add a property that holds a reference to the class instance, but if you're lazy you can add do this:

class SomeClass {
var myxml:Object; //so you can dynamically add a property to it
...
function load(url:String):Void {
	var myxml = new XML();
	myxml.refToClassInstance = this;
        myxml.ignoreWhite = true;
	myxml.onLoad = function(success:Boolean) {
		if (success) {
			var categoryNodes:Array = this.firstChild.childNodes;	
			for (var i = 0; i < categoryNodes.length; i++) {
				var c:Category = this.refToClassInstance.addCategory(categoryNodes[i].attributes.label);
			}
		} else {
			trace("There was an error parsing the XML data");
		}
	};
	_xml.load(url);
}
}

pretty neat huh... hope this is useful to somebody else too
