Loading and viewing XML when a class object is created..Help Please

Question

Hello,
I have writing a simple class which has a method that gets invoke when the object of the class is created. I am able to view the loaded XML content when I trace it with in my class method, but cannot assign the content to a instance variable using the mutator method. So the process goes like this:
Class object is instantiated
Class construtor then calls the loadXML method which laods the XML
And then assigns the XML to a class instance variable.
So now if I would like to access the loaded XML through class object, I should be able to see the loaded xml content which I am not able to see. I have spent over few hours and cannot get the class object to display the loaded XML content. I would highly appreciate it if someone can help in the right direction, please.

Answer 1

where you have:
            super();
            c = new Cars();  
            trace(c.Cars);
c.Cars will not trace as the loaded xml, because it will not have loaded in time. After some time it should presumably have the correct value.
loading operations in actionscript are asynchronous, so your nested function which is acting as the listener ( function processXML(e:Event):void) only ever executes when the raw xml data has loaded and that is (I believe, not 100% sure) always at least one frame subsequent to the current one.
In general I would consider it bad practise to use nested functions like that, but I don't think its contributing to your issues here. I think its just a timing issue given how things work in flash....
Additional observation:
your Cars constructor calls loadCars() and your loadCars method is defined as:
public function loadcars()
I assume its just a typo in the forum that the uppercase is missing in the function name....
