[Flashcoders] AS3: How can I target an object from a dot-sytax string?

[Ali Drongo]

Hello, I'm being passed a string that has a reference to an object in  
dot-syntax like this:  "myOb.property.property2.property3"

The object targeted may be a varying number of levels inside of the  
top-level object.

I have tried to write this by turning the string into an array and  
then creating the object but I'm not sure how:

public static function arToObj(a:Array):Object
                {
                        var retObj:Object;
                        for ( var i:Number=0; i<a.length; i++ ) {
                                if (i==a.length-1){
                                        //dont know what to do here !!
                                }
                        };
                        return retObj;
                }


Am I going about this the right way or have I missed something obvious?

Any suggestions received gladly:)
Ali
