运行结果​

在示例中，第一个流程注入以下 XML 数据：

<note priority="high">
  <to>Nick</to>
  <from>Dave</from>
  <heading>Reminder</heading>
  <body>Update the website</body>
</note>

然后，XML 节点将其转换为等效的 JavaScript 对象：

{
    "note": {
        "$": {
            "priority":"high"
        },
        "to": ["Nick"],
        "from": ["Dave"],
        "heading": ["Reminder"],
        "body": ["Update the website"]
    }
}
