我使用了这个树数据结构。 https://github.com/nicmart/Tree
并从以下xml代码创建了一个树对象，它们都显示在下面：
<xgameapp version="1.0">
<states>
<state id="1" color="red"></state>
<state id="2" color="blue">
Hello state
</state>
</states>
<actions>
<transitions>
<transition from="1" to="2">
This is a demo Transition
</transition>
<transition from="2" to="1"></transition>
</transitions>
<Orientations>
<x1>
<y1>
<cw>
<Orientation fronAngle="120" toAngle="45"></Orientation>
<Orientation fronAngle="270" toAngle="120"></Orientation>
</cw>
<ccw>
<Orientation fronAngle="45" toAngle="120"></Orientation>
<Orientation fronAngle="120" toAngle="270"></Orientation>
</ccw>
</y1>
</x1>
</Orientations>
</actions>
</xgameapp>

现在我试图将此输出表示为嵌套数组或任何对人眼友好的方式。
感谢。
