XmlDocument.CreateAttribute 效果演示

using System;
using System.IO;
using System.Xml;

namespace CreateAttribute
{
/// <summary>
/// Class1 的摘要说明。
/// </summary>
class Class1
{
  /// <summary>
  /// 应用程序的主入口点。
  /// </summary>
  [STAThread]
  static void Main(string[] args)
  {
   //
   // TODO: 在此处添加代码以启动应用程序
   //
   XmlDocument doc = new XmlDocument();
   doc.LoadXml("<book genre=novel ISBN=1-861001-57-5>" +
    "<title>Pride And Prejudice</title>" +
    "</book>");

   //Create an attribute.
   XmlAttribute attr = doc.CreateAttribute("publisher");
   attr.Value = "WorldWide Publishing";

   //Add the new node to the document.
   doc.DocumentElement.SetAttributeNode(attr);

   Console.WriteLine("Display the modified XML...");
   doc.Save(Console.Out);
  }
}
}

效果如下：
Display the modified XML...
<?xml version="1.0" encoding="gb2312"?>
<book genre="novel" ISBN="1-861001-57-5" publisher="WorldWide Publishing">
<title>Pride And Prejudice</title>
</book>Press any key to continue

XmlDocument.CreateNode 方法效果演示

using System;
using System.Xml;

namespace CreateNode
{
/// <summary>
/// Class1 的摘要说明。
/// </summary>
class Class1
{
  /// <summary>
  /// 应用程序的主入口点。
  /// </summary>
  [STAThread]
  static void Main(string[] args)
  {
   //
   // TODO: 在此处添加代码以启动应用程序
   //
   XmlDocument doc = new XmlDocument();
   doc.LoadXml("<book>" +
    " <title>Oberons Legacy</title>" +
    " <price>5.95</price>" +
    "</book>");

   // Create a new element node.
   XmlNode newElem;
   newElem = doc.CreateNode(XmlNodeType.Element, "pages", "");
   newElem.InnerText = "290";

   Console.WriteLine("Add the new element to the document...");
   XmlElement root = doc.DocumentElement;
   root.AppendChild(newElem);

   Console.WriteLine("Display the modified XML document...");
   Console.WriteLine(doc.OuterXml);
  }
}
}

效果：
Add the new element to the document...
Display the modified XML document...
<book><title>Oberons Legacy</title><price>5.95</price><pages>290</pages></book>
