【问题描述】：

在解析从 NodeJS 中 SOAP Web 服务的 XML 响应创建的 JSON 时，我需要帮助。我想要一个 notifications 的 JSON 数组。

XML如下：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <ns2:getNotificationsResponse xmlns:ns2="---url---">
         <return>
            <notifications>
               <ackRequired>false</ackRequired>
               <body>Testing Notitfications</body>
               <created>1498798404874</created>
               <gpsAlt>1.0</gpsAlt>
               <gpsLat>1.0</gpsLat>
               <gpsLong>1.0</gpsLong>
               <messageId>253</messageId>
               <priority>INFORMATIONAL</priority>
               <senderClientId>PMC0</senderClientId>
               <status>SENT</status>
               <subject>Test Notification</subject>
               <updated>1498798404874</updated>
               <userId>1</userId>
               <userLogin>ipics</userLogin>
            </notifications>
            <notifications>
               <ackRequired>false</ackRequired>
               <body>Test notitfication</body>
               <created>1498797535714</created>

               <subject>Test</subject>
               <updated>1498797535714</updated>
               <userId>1</userId>
               <userLogin>ipics</userLogin>
            </notifications>
            <notifications>
               <ackRequired>false</ackRequired>
               <body>Testing Notitfications</body>

               <gpsAlt>1.0</gpsAlt>
               <gpsLat>1.0</gpsLat>

            </notifications>
         </return>
      </ns2:getNotificationsResponse>
   </soap:Body>
</soap:Envelope>

我正在使用 xmldom 节点模块。
我的代码如下，但没有给出正确的响应。

var doc = new DOMParser().parseFromString(data.response, 'text/xml');
var valueXML = doc.getElementsByTagName('return');
var temp = valueXML[0].getElementsByTagName("notifications")[0];
var output = temp.getElementsByTagName("nextSibling")._node.childNodes.parentNode

【问题讨论】：

valueXML[0].children怎么样
@ShanilFernando，它返回未定义

标签： json node.js xml xmldom

【解决方案1】：

const transform = require('camaro')
const fs = require('fs')

const xml = fs.readFileSync('so.xml', 'utf-8')
const template = {
    notifications: ['//notifications', {
        ackRequired: 'ackRequired',
        body: 'body',
        created: 'created',
        gpsAlt: 'number(gpsAlt)'
    }]
}

const result = transform(xml, template)
console.log(JSON.stringify(result, null, 2))

然后输出：

{
  "notifications": [
    {
      "ackRequired": "false",
      "body": "Testing Notitfications",
      "created": "1498798404874",
      "gpsAlt": 1
    },
    {
      "ackRequired": "false",
      "body": "Test notitfication",
      "created": "1498797535714",
      "gpsAlt": 0
    },
    {
      "ackRequired": "false",
      "body": "Testing Notitfications",
      "created": "1498794764538",
      "gpsAlt": 1
    },
    {
      "ackRequired": "false",
      "body": "Testing Notitfications",
      "created": "1498794760123",
      "gpsAlt": 1
    }
  ]
}

我只是在模板中添加了几个字段来测试。您可以根据需要添加更多基础。

【讨论】：

如果我不知道字段怎么办？
@DarshanaAhalpara 我写这个包的目的是为了将 xml 转换为 json，但是你必须自己写模板（你知道输入的格式）。但如果不是这种情况，您可能需要为此找到另一个包。
另外，如果它适合你，你能把它标记为答案吗:)
您的模块在 Windows 上运行良好，但是当我在 Red Hat 上尝试时，它给了我错误，因为 g++ 构建失败。我无权在 red hat 系统上安装 gcc 编译器，有没有其他方法可以让它工作？
另外，它需要 gcc 4.9（我认为现在大多数发行版都是默认的）。

【解决方案2】：

试试这个。您可以在 JSON 中随意映射它。我只是告诉你方向。

【讨论】：

property.innerHTML 给出未定义的。
@DarshanaAhalpara 检查控制台输出https://jsfiddle.net/48qjec55/3/。我没有收到任何错误
我在属性中获得了 html 标签。但是当试图触发 property.innerHTML 时，它给出了 undefined。
“fire property.innerHTML”是什么意思？
当我试图从 property.innerHTML 中获取价值时。
