Hi. I appreciate the help!

I have a class with a XML object in it. In one of the class’ methods, I tell the XML object to load a document. Before I do that, I set up the onLoad event to call one of the class’ other methods. The problem is that in that handler function, I can’t seem to access any of my class’ data. If I try to use the “this” pointer, I’m getting the XML object not my class.

A simple example:

[AS]  
class MyClass  
{  
var theXML:XML;  
var someVariable:Number;

function MyClass()  
{  
theXML = new XML();  
theXML.onLoad = XMLLoadHandler;  
theXML.load( “testFile.xml” );  
}

function XMLLoadHandler(success)  
{  
// This function gets called when the XML is done parsing,  
// but I can’t access any of the data or methods in this class!!  
// What do I need to do?  
trace(someVariable); // does not exist  
}  
}  
[/AS]

Thanks!!

For your class use this  
[AS]  
class MyClass extends XML  
{  
var theXML:XML;  
var someVariable:Number;

```
    function MyClass()
    {
            this.theXML = new XML();
            this.theXML.onLoad = this.XMLLoadHandler();
            this.theXML.load( "testFile.xml" );
    }
    
    function XMLLoadHandler(success)
    {
            // This function gets called when the XML is done parsing,
            // but I can't access any of the data or methods in this class!!
            // What do I need to do?
            trace("this is to test my class"); // does not exist
    }

```

}  
[/AS]

Then on your main scene in a ‘actions’ layer…add this script to call the class.  
[AS]  
import myClass

\_root.onLoad = function()  
{  
var myVar:MyClass = new MyClass();  
trace(myVar.ignoreWhite); //These two lines of code are 2 show that you have inheritted the XML class properties  
trace(myVar.firstChild); //And to show that you can set the properties outside your class  
}  
[/AS]

If I havn’t understood correctly, please explain again so I can help out.

Cheers
