xml - JSON.NET 和替换 @Sign in XML 到 JSON 的转换

Question

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。我宁愿在将它发送到 View 之前删除它。最好的方法是什么？

我知道我可以直接替换，但 @ 字符可能与某处相关，不应被替换。有正则表达式吗？

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"
              }
            ]
          }
        }
      }
    ]
  }
}

我花了很长时间才找到正确的答案，所以我想分享一下:

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"}}}
