How to convert JSON to XML or XML to JSON ?

code:

// To convert an XML node contained in string xml into a JSON string   

XmlDocument doc = new XmlDocument();

doc.LoadXml(xml);

string jsonText = JsonConvert.SerializeXmlNode(doc);

// To convert JSON text contained in string json into an XML node

XmlDocument doc = JsonConvert.DeserializeXmlNode(json);

 JSON -> XML

You need a top level object that will convert to a root XML element or the parser will fail.

Your object names cannot start with a number, as they cannot be converted to elements (XML is technically even more strict than this) but I can 'get away' with breaking some of the other element naming rules.

XML -> JSON

All data becomes string data (for example you will always get "false" not false or "0" not 0) Obviously JavaScript treats these differently in certain cases.

Children elements can become nested-object {} OR nested-array [ {} {} ...] depending if there is only one or more than one XML child-element. You would consume these two differently in JavaScript, etc. Different examples of XML conforming to the same schema can produce actually different JSON structures this way. You can add the attribute json:Array='true' to your element to workaround this in some (but not necessarily all) cases.

Your XML must be fairly well-formed, I have noticed it doesn't need to perfectly conform to W3C standard, but 1. you must have a root element and 2. you cannot start element names with numbers are two of the enforced XML standards I have found when using Newtonsoft and MS libraries.

In older versions, Blank elements do not convert to JSON. They are ignored. A blank element does not become "element":null.
