[flexcoders] calling different methods through XML and Flash Proxy class?

[Corey Smaller]

ok, im a little confused.  I need to be able to call many different
methods based on whatever comes in through the XML (ie- the XML would
have a "function" node that names a preexisting function to handle
whatever data comes in). My idea is to have one class that sends and
receives the XML (DatabaseRequest.as for example) and then calls
whatever function/class to set up the proper swf based on the XML
data. like this

<function>createVideoSection</function>

Instead of using a ton of if/then statements is there an easier way to
just call the function (even though the data comes in as XML) or
create a class that interprets it??

 I read a few examples on the Proxy class and maybe i am going in the
right direction? its friday, Im tired, and its raining. 

from what I have read on the Proxy class you need to override
flash_proxy_function CallProperty like so (taken from livedocs):

//code 

 override flash_proxy function callProperty(methodName:*, ... args):* {
        var res:*;
        switch (methodName.toString()) {
            case 'clear':
                _item = new Array();
                break;
            case 'sum':
                var sum:Number = 0;
                for each (var i:* in _item) {
                    // ignore non-numeric values
                    if (!isNaN(i)) {
                        sum += i;
                    }
                }
                res = sum;
                break;
            default:
                res = _item[methodName].apply(_item, args);
                break;
        }
        return res;
    }

//end code
