I'd write that like this:
class ParseXML {
private var _xmlDoc : XML;
function ParseXML( url : String ) {
_xmlDoc = new XML();
_xmlDoc.ignoreWhite = true;
_xmlDoc.onLoad = function () {
trace( this );
};
_xmlDoc.load( url );
}
}
Clearer? The original version isn't defining a method for the class,
it's defining a function and assigning it to a variable. In the spirit
of calling a spade a spade, it's better to define an anonymous function
where it's actually used.
