Adobe Flex Filter XMLList

Question

下面是我的XML文件的摘录：

 <car>
  <carname>AC</carname>
  <carmodellist>
    <carmodel>Cobra</carmodel>
  </carmodellist>
</car>

如何查询xmllistcollection并返回carmodellist中carname ==为'AC‘的所有汽车？

我已经尝试了几种组合，但都没有成功，我想应该是这样的：

var models:XMLListCollection = new XMLListCollection(vehicles.child(@car=='AC').carmodellist.children());

Answer 1

如果您有如下xml：

<cars>
    <car>
        <carname>AC</carname>
        <carmodellist>
            <carmodel>Cobra</carmodel>
            <carmodel>Cobra2</carmodel>
        </carmodellist>
    </car>
    <car>
        <carname>AB</carname>
        <carmodellist>
            <carmodel>Bobra</carmodel>
        </carmodellist>
    </car>
    <car>
        <carname>AD</carname>
        <carmodellist>
            <carmodel>Dobra</carmodel>
        </carmodellist>
    </car>
</cars>

然后：

vehicles.car.(carname == 'AC').carmodellist.children()
