<source lang="csharp">using System;
using System.Xml;
class MainClass
{
static void Main(string[] args)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml("<Record> Some Value </Record>");
XmlNode node1 = xmlDoc.CreateComment("DOM Testing Sample");
xmlDoc.AppendChild( node1);
node1 = xmlDoc.CreateElement("FirstName");
node1.InnerText = "M";
xmlDoc.DocumentElement.AppendChild(node1);
xmlDoc.Save(Console.Out);
}
}</source>
<pre class=codeResult><?xml version="1.0" encoding="gb2312"?>
<Record> Some Value <FirstName>M</FirstName></Record>

==Create XML document by specifying the elements==

<source lang="csharp">using System;
using System.Collections;
