I don't even know why I'm responding to this, but. Ktu gave you the answer
yet you seemed to ignore it? You don't need an eval at all.
function getNumItems(level:int, xml:XML):int{
var levelXML:XML = xml.menu;
for(var i:int = 0; i < level; i ++){
levelXML = levelXML.item[whichItems[level]];
}
return levelXML.length();
}
does exactly what this would do, if AS3 had an eval:
var j:String = "xml.menu.item[whichItems[0]]";
var k:String = new String();
var l:int = level;
while (l--)
{
k += ".item[whichItems[" + String(l) + "]]";
}
totalItems = (j + k);
