我有一个像这样的xml字符串
string stxml="<Status>Success</Status>";
我还创建了一个xml文档
XmlDocument doc = new XmlDocument();
XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
doc.AppendChild(docNode);
XmlNode rootNode = doc.CreateElement("StatusList");
doc.AppendChild(rootNode);
我需要这样的输出。
<StatusList>
<Status>Success</Status>
</StatusList>
如何实现这一点。如果我们使用innerhtml,它会插入。但我想将xml字符串作为xmlnode本身插入

实现目标的一种非常简单的方法是使用经常被忽视的XmlDocumentFragment类:
XmlDocument doc = new XmlDocument();
XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
doc.AppendChild(docNode);
XmlNode rootNode = doc.CreateElement("StatusList");
doc.AppendChild(rootNode);
//Create a document fragment and load the xml into it
XmlDocumentFragment fragment = doc.CreateDocumentFragment();
fragment.InnerXml = stxml;
rootNode.AppendChild(fragment);

使用Linq to XML
:
string stxml = "<Status>Success</Status>";
XDocument doc = new XDocument(new XDeclaration("1.0", "utf-8", "yes"),
new XElement("StatusList", XElement.Parse(stxml)));

您可以改为使用XElement
类:
string stxml = "<Status>Success</Status>";
var status = XElement.Parse(stxml);
var statusList = new XElement("StatusList", status);
var output = statusList.ToString(); // looks as you'd like
如果要将新的statusList
内容写入文件:
statusList.Save(@"C:\yourFile.xml", SaveOptions.None);

您可以使用xmlwriter
进行尝试using (XmlWriter writer = XmlWriter.Create("new.xml"))
{
writer.WriteStartDocument();
writer.WriteStartElement("StatusList");
writer.WriteElementString("Status", "Success"); // <-- These are new
writer.WriteEndDocument();
}
