Simple question: hows to dynamically reference a class object

Hi i need a little help as my brain has gone dark on me :-)

i have the below object backupCartItem (simplified)

and i have a function which needs to reference different properties within the different contained objects.

public function createEndorcementItem( propertyClass:String, propertyName:String ):void
{
var val:* = backupCartItem[ propertyClass ][ propertyName ];
trace( val.toString();
}

public function doSomething():void
{
createEndorcementItem( 'sessionVO.primaryInsurie', 'AGE_NOW');
}

the above little script example should set val to being
backupCartItem.sessionVO.primaryInsurie.AGE_NOW

but it throws an error

Property sessionVO.primaryInsurie not found on com.travins.cairngorm.model.CartItemVO

how can i dynamically reference the object please

Actually if checked in debuger your example isnt right im afraid

backupCartItem      Object (@8cb9421)
      sessionVO.primaryInsurie      Object (@8cb93f9)
            AGE_NOW      25 [0x19]

as per my original which is what my object dump looks like

backupCartItem com.travins.cairngorm.model.CartItemVO (@70bd781)
sessionVO com.travins.cairngorm.model.CurrentSessionVO (@27a2881)
primaryInsurie com.travins.cairngorm.model.InsurieVO (@1fa5dc1)
AGE_IS_VALID true
AGE_NOW 40 [0x28]

please notice that in your example the primaryInsurie object isnt nested inside sessionVO

ok i have found a solution finally your comment gave me an idea which worked so thanks for the pointers

here is my solution but im sure its a dirty method and that there must be a cleaner way!!!

public function createEndorcementItem( propertyClass:String, propertyName:String ):void
{
	var arr:Array = propertyClass.split(".");
				
	var cur:Object;
	cur = backupCartItem;
				
	for each (var a:String in arr)
	{
		cur = cur[a];
	}
	var val:* = cur[propertyName];
}
