如何在没有根节点的情况下保存Xdocument

Question

我将soap序列化的xml文件以追加模式添加到文件，这将导致多个根节点如下所示

我这样做是为了加载XDocument

 StreamReader Sr = new StreamReader(filename);
 XDocument doc = XDocument.Parse("<rootnode>" + Sr.ReadToEnd() + "</rootnode>");

然后我对文档做了一些修改，最后我希望它不带根节点保存，

<?xml version="1.0" encoding="utf-8"?> 

当我这样做的时候

doc.Save(filename);

我想不带根节点保存它，因为我可以再次反序列化该文件

因此，请为我提供任何替代方法来实现...

提前感谢

这将得到不带根节点的xml。

StringBuilder sb = new StringBuilder();
doc.Root.Elements().ToList().ForEach(x => sb.Append(x.ToString()));
string xmlWithoutRootNodes = sb.ToString();
File.WriteAllText("file", xmlWithoutRootNodes);
