如何在沒有根節點的情況下保存Xdocument

Question

我在附加模式下將肥皂序列化的xml文件添加到文件中，這將導致像這樣的多個根節點

<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:clr="http://schemas.microsoft.com/soap/encoding/clr/1.0" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

我這樣做是為了加載XDocument

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

然后，我對doc進行了一些修改，最后我希望將其保存而沒有根節點

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

當我做

doc.Save(filename);

我想保存它而沒有根節點，因為再次可以反序列化文件

因此，請提供任何其他替代方法來實現...。

提前致謝

這將為您提供沒有根節點的xml。

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