Hi,
I am having some issues with e4x filtering when I try and use a
"dynamic" element in my expressions...
Using the XML below (somewhat truncated) I am trying to match either
the "id" or the "name" depending on the variable type passed in:
private function _subscriberEventNameFromIds(objId:* = 0, funcId:int
= 0, is_func:Boolean = true):String {
var objName:String;
var funcName:String;
//_subscriptionList contains the XML below...
//....
var obj:XMLList;
var idx:String = "name";
if(objId is int) {
idx = "id";
}
//The following expression does not work, I cannot use idx
"dynamically"..
obj = _subscriptionList.object.(child(idx) == objId);
//..., instead I have to do the following.
/*
if(objId is int) {
idx = "id";
obj = _subscriptionList.object.(child("id") == int(objId));
} else {
obj = _subscriptionList.object.(child("name") ==
String(objId));
}
*/
}
Does anyone know if /how I can do this dynamically?
