[Flex] 递归 删除XML 节点

一定要用索引，而且删除的对象要是XMLList里面的元素，不然会报错，或者不能删除！

   1: private function delNoHelpNode(xmllist1:XMLList):void{

   2:    for each(var item:XML in xmllist1){

   3:      if(item.@checked == "0"){

   4:         delete xmllist1[item.childIndex()];

   5:        }else if(item.@checked == "1"){

   6:           if(item.hasComplexContent())

   7:                arguments.callee(item.children());

   8:             }                             

   9:         }

  10:  }
