android - 如何从这棵树中遍历并获取它们的属性？

Question

<?xml version="1.0" encoding="utf-8"?>
<parent>

<child ID="1" Name="CHILD" Order="1">

<child ID="1" Name="SUB_CHILD" Order="1">
<child ID="1" Name="SUB_CHILD_1" Order="01"/>
<child ID="2" Name="SUB_CHILD_2" Order="02"/>
</child >

</child>

<child ID="2" Name="CHILD_2" Order="1">

<child ID="1" Name="SUB_CHILD" Order="1">
<child ID="1" Name="SUB_CHILD_1" Order="01"/>
<child ID="2" Name="SUB_CHILD_2" Order="02"/>
</child >

</child>

</parent>

这是我获取<child ID="1" Name="CHILD" Order="1">名称的代码：

NodeList nodeList = doc.getElementsByTagName("child");

        Element element = (Element) nodeList.item(0);
        name = element.getAttribute("Name");            

        Toast.makeText(this, ""+ name, Toast.LENGTH_SHORT).show();

我如何获得以下名称：

<child ID="1" Name="SUB_CHILD" Order="1">
<child ID="1" Name="SUB_CHILD_1" Order="01"/>

我已经尝试过 getChildNode 但它只返回任何内容。
