如何从字符串或xml中删除XML声明+根标记

Question

I have an XML with xml declaration + root tag , which i don't need -> my goal is convert it to JSON, without xml declaration and root tag

var xml = XDocument.Parse(renderedOutput);
var xmlWithoutRoot = JsonConvert.SerializeXNode(xml, Newtonsoft.Json.Formatting.None, true);
// convert XML to JSON
var newJson = Newtonsoft.Json.JsonConvert.SerializeObject(xmlWithoutRoot);

How can i remove the XML deceleration <?xml version="1.0" encoding="UTF-8"?> from the xml, before serialize it to JSON?

For removing XML declaration, you can use XElement instead of XDocument , for example :

var renderedOutput = @"<?xml version=""1.0"" encoding=""utf-8"" ?>
  <root>
   <foo>bar</foo>
 </root>";
var xml = XElement.Parse(renderedOutput);
var xmlWithoutRoot = JsonConvert.SerializeXNode(xml, Newtonsoft.Json.Formatting.None, true);
// convert XML to JSON
var newJson = JsonConvert.SerializeObject(xmlWithoutRoot);
Console.WriteLine(newJson);

output :

"{\"foo\":\"bar\"}"
