Question

我正在使用JsonConvert将Json对象反序列化为XML，但由于Json对于同一级别的元素具有不同的结构，因此我在生成的XML中获得了重复的节点。

我的Json看起来像这样：

{
    "shipments": [
        {
            "id": "A000001",
            "name": "20141208 140652",
            "type": "OUTLET",
            "date": "2014-12-08 14:06:52",
            "status": "SENT",
            "received_at": null,
            "created_at": "2014-12-08 14:06:52",
            "updated_at": null,
            "outlet_id": "SH000064"
        },
        {
            "id": "A000002",
            "name": "20141204 122650",
            "type": "SUPPLIER",
            "date": "2014-12-04 12:26:50",
            "outlet_id": "SH000064",
            "supplier_id": null,
            "status": "RECEIVED",
            "received_at": "2014-12-04 12:28:43",
            "created_at": "2014-12-04 12:26:50",
            "updated_at": "2014-12-04 12:28:43"
        }
    ]
}

转换后，XML看起来像这样：

<root>
  <shipments>
    <id>A000001</id>
    <name>20141208 140652</name>
    <type>OUTLET</type>
    <date>2014-12-08 14:06:52</date>
    <status>SENT</status>
    <received_at />
    <created_at>2014-12-08 14:06:52</created_at>
    <updated_at />
    <outlet_id>SH000064</outlet_id>
  </shipments>
  <shipments>
    <id>A000002</id>
    <name>20141204 122650</name>
    <type>SUPPLIER</type>
    <date>2014-12-04 12:26:50</date>
    <outlet_id>SH000064</outlet_id>
    <supplier_id />
    <status>RECEIVED</status>
    <received_at>2014-12-04 12:28:43</received_at>
    <created_at>2014-12-04 12:26:50</created_at>
    <updated_at>2014-12-04 12:28:43</updated_at>
    <outlet_id>SH000064</outlet_id>
  </shipments>
</root>

我用来转换Json的代码是：

var document = JsonConvert.DeserializeXmlNode(json, "root");
var xml = document.OuterXml;

问题是第二个货件元素中的outlet_id节点重复。输入Json通过验证，所以我认为这是一个常见问题。有办法吗？

更新：进一步调试显示在提交和处理HttpWebRequest期间引入了额外节点。如果我通过Postman应用程序调用REST服务，我会得到上面给出的Json（为简单起见，使用截断）。如果我通过我的C＃代码调用该服务，我会改为：

{
    "shipments": [
        {
            "id": "A000001",
            "name": "20141208 140652",
            "type": "OUTLET",
            "date": "2014-12-08 14:06:52",
            "status": "SENT",
            "received_at": null,
            "created_at": "2014-12-08 14:06:52",
            "updated_at": null,
            "outlet_id": "SH000064"
        },
        {
            "id": "A000002",
            "name": "20141204 122650",
            "type": "SUPPLIER",
            "date": "2014-12-04 12:26:50",
            "outlet_id": "SH000064",
            "supplier_id": null,
            "status": "RECEIVED",
            "received_at": "2014-12-04 12:28:43",
            "created_at": "2014-12-04 12:26:50",
            "updated_at": "2014-12-04 12:28:43",
            "outlet_id": "SH000064"
        }
    ]
}

我用来提交请求和处理响应的代码是：

HttpWebRequest request = WebRequest.Create(Uri.EscapeUriString(url)) as HttpWebRequest;
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
var responseStream = reader.ReadToEnd();
reader.Close();

此阶段的断点显示附加节点已添加到通过流式传输响应返回的Json。

执行相同的调用，其中返回的数据都是相同的类型，因此结构，不会创建重复的节点，因此，这可能是由一个＆＃34;货物＆＃34;元素与同行的结构不同。

在将Json转换为XML时，有没有办法防止重复的XML节点？
