JSON.NET 和替换 @ 登录 XML 到 JSON 转换 [英] JSON.NET and Replacing @ Sign in XML to JSON converstion

问题描述

JSON.NET 框架可以将 XML 转换为 JSON，但它使用 JSON 中的 @ 符号作为属性.我宁愿在将其发送到视图之前将其删除.最好的方法是什么?

The JSON.NET framework can convert XML to JSON, but it uses the @ sign in the JSON as the attribute. I would rather remove this before sending it to the view. What would be the best approach for this?

我知道我可以直接替换，但 @ 字符可能在某处相关并且不应该被替换.这有正则表达式吗?

I know I can do a straight up replace, but an @ character may be relevant somewhere and shouldn't be replaced. Is there a Regex for this?

public ActionResult Layout()
{
    var xml = new XmlDocument();
    xml.XmlResolver = null;
    xml.Load(Server.MapPath("~/App_Data/Navigation.xml"));
    return Content(JsonConvert.SerializeXmlNode(xml, Newtonsoft.Json.Formatting.Indented));
}

{
  "Layout": {
    "Navigation": [
      {
        "@Type": "Menu",
        "@Title": "Dashboard"
      },
      {
        "@Type": "Menu",
        "@Route": "Events",
        "@Title": "Events",
        "Navigation": {
          "@Type": "Action",
          "@Route": "Event",
          "@Title": "+ Add Event",
          "@Order": "1",
          "Navigation": {
            "@Type": "Item",
            "@Route": "Event",
            "@Name": "Event",
            "Navigation": [
              {
                "@Route": "Pools",
                "@Type": "SubNavigation",
                "@Name": "Pools"
              },
              {
                "@Route": "Brackets",
                "@Type": "SubNavigation",
                "@Name": "Brackets"
              }
            ]
          }
        }
      }
    ]
  }
}

推荐答案

我找了好久才找到正确答案，所以我想我会分享:

It took me quite a while to find the right answer, so I thought I'd share:

var xDocument = XDocument.Parse("<xml><a attr="b">c</a></xml>");
var builder = new StringBuilder();
JsonSerializer.Create().Serialize(new CustomJsonWriter(new StringWriter(builder)), xDocument);
var serialized = builder.ToString();

public class CustomJsonWriter : JsonTextWriter
{
    public CustomJsonWriter(TextWriter writer): base(writer){}

    public override void WritePropertyName(string name)
    {
        if (name.StartsWith("@") || name.StartsWith("#"))
        {
            base.WritePropertyName(name.Substring(1));
        }
        else
        {
            base.WritePropertyName(name);
        }
    }
}

输出:

{"xml":{"a":{"attr":"b","text":"c"}}}
