Two main things (note .. this is psudo code):
1. Once the xml load has completed, set that xml object , i.e
public function setMyXML(xmlObj:XML):void{
}
public function getMyXML():XML{
}
2. Make this class available as a reference to the class that will use the
data. Because the aforementioned setter function is public, you will have
access to it. So when you initialize the class that will be using xml data,
you need to pass a reference to the xml-containing class...as long as you
are initializing your data and config objects before your display/controls
objects... and you should be doing that.
i.e. displayClass() = new DisplayClass;
displayClass.setXMLInstance(xmlClass.getMyXML());
I sometimes take my xml properties and make them into a series of arrays or
associative arrays so I don't have to deal with xml trees in other classes,
but some see that as overkill.
good luck.
