<mx:HTTPService id="xmlData" url="http://www.flexgrocer.com/units.xml" result="resultHand(event)">
</mx:HTTPService>
<mx:Script>
<![CDATA[

[Bindable]
private var xmls:ArrayCollection = new ArrayCollection();
[Bindable]
public var i:int = 0;

private function resultHand(event:ResultEvent):void{
//xmls = event.result.allunits.unit; //这一行event.result后面怎么才能访问到XML里面的allunits节点呢？现在访问不到
xmls = event.result.allUnits.unit; //比较一下我们的代码差别就在于allunits写错了应该是allUnits
xmls[0].unitName
Alert.show(xmls[0].unitName);
}

关键就在与你的allunits写错了,应该是allUnits.
