XmlElement XMLE = (XmlElement)TreeV.SelectedItem;
XmlDocument xdoc = new XmlDocument();
xdoc.Load(scd_file);
XmlDocumentFragment xfrag = xdoc.CreateDocumentFragment();
xfrag.InnerXml = text;
XmlDocumentFragment xfrag1 = xdoc.CreateDocumentFragment();
xfrag1.InnerXml = XMLE.OuterXml;
xdoc.ReplaceChild(xfrag, xfrag1);
But it shows error (xfrag1 is not a node of xdoc) please help me to solve this problem. 但是它显示错误(xfrag1不是xdoc的节点),请帮助我解决此问题。

XmlDocument XD = new XmlDocument();
XD.LoadXml(text);// text is edited part save as a string
XmlNode root=XD.DocumentElement;
XmlDocument xml = XMLE.ParentNode.OwnerDocument;
XmlNode import= xml.ImportNode(root, true);
XMLE.ParentNode.ReplaceChild(import, XMLE);
xml.Save(scd_file); //scd_file path
