Flex使用XML点表示法字符串

In the following example the first trace gives me the xml data at the node, but the second trace does not. This is AS3. How would I use a variable to do the same as inline dot notation?

在下面的示例中，第一个跟踪为我提供了节点上的xml数据，但第二个跟踪没有。这是AS3。我如何使用变量与内联点表示法相同？

var x:String = "animXML.home.version";
trace(animXML.home.version);  // this works
trace([x]);                   // this does not

Thanks

谢谢

Not sure what you are trying to achieve but this will output same thing:

不确定你想要实现什么，但这将输出相同的东西：

var x:String = animXML.home.version as String;
trace(animXML.home.version);  // this works
trace(x);                     // this works

update (full script):
