        XmlElement xmldata = xmlDoc.CreateElement("data");
                    XmlElement xmlcontent = xmlDoc.CreateElement("content");

                    xmldata.InnerText ="1234" ;
        xmlcontent.InnerText ="Stackoverflow";

                    newelement.AppendChild(xmldata);
        newelement.AppendChild(xmlcontent);

                    xmlDoc.DocumentElement.AppendChild(newelement);
        xmlDoc.Save(@"C:\Log_Data.xml");

XPath is a query language for XML documents. As such, it doesn't provide the capability to alter (delete or insert nodes) an XML document.

One of the most appropriate ways to create or alter an XML document (called XML transformation) is to use XSLT -- a language especially designed for XML transformations.

From C# one can use the .NET XslCompiledTransform class to perform any XSLT 1.0 transformation.

Third party .NET implementations exist for XSLT 2.0.

You have to create your own XPath parser to achieve this. Simple implementation of that can be found here.
