JSON.NET and Replacing @ Sign in XML to JSON converstion

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);        }    }}

Output:

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

I went ahead and used this. Let me know if there is a better way.

public ActionResult Layout(){    var xml = new XmlDocument();    xml.XmlResolver = null;    xml.Load(Server.MapPath("~/App_Data/Navigation.xml"));    var jsonText = JsonConvert.SerializeXmlNode(xml, Newtonsoft.Json.Formatting.Indented);    return Content(Regex.Replace(jsonText, "(?<=\")(@)(?!.*\":\\s )", string.Empty, RegexOptions.IgnoreCase));}

The Regex not always work great,when content has the @ character and in the first place,that will be replace too.so I think(?<!:)(\"@)(?!.\":\\s ) may be better.
