Result:

<AwayScore xmlns:i="http://www.w3.org/2001/XMLSchema-instance">21</AwayScore>

需要：输出： 20 26 21

情况：我正在调用API，它给我结果（XML）作为主要节点ArrayOfScore之后的那个得分日期是我想要的。但我一直收到错误“TypeError：错误＃1034：类型强制失败：无法将XMLList @ c1e1fd1转换为mx.collections.ArrayCollection。”

您必须重写下面指定的代码

protected function NFLScore_resultHandler(event:ResultEvent):void
            {
                var obj:SomeObject = null;//someobject is any class that stores the xml data that is returned from the server. 
                for(XML item:event.result.ArrayOfScore.Score){
                      obj = new SomeObject();
                      obj.someProperty = item.toString();
                      myData.additem(obj);
                }
            }

基本上你正在做的是，通过上面的迭代将一个对象（xmllist）类型转换为arraycollection对象。这可能不完美，但是，shoudl会给你一个开始研究它的想法。
