XML文件:
<?xml version= "1.0 " encoding= "gb2312 "?>
<bookstore>
<book genre= "fantasy " ISBN= "2-3631-4 ">
<title> Oberon 's Legacy </title>
<author> Corets, Eva </author>
<price> 5.95 </price>
</book>
</bookstore>
1、插入节点
往 <bookstore> 节点中插入一个 <book> 节点：
XmlDocument xmlDoc=new XmlDocument();
xmlDoc.Load( "bookstore.xml ");
XmlNode root=xmlDoc.SelectSingleNode( "bookstore ");//查找 <bookstore>
XmlElement xe1=xmlDoc.CreateElement( "book ");//创建一个 <book> 节点
xe1.SetAttribute( "genre ", "李赞红 ");//设置该节点genre属性
xe1.SetAttribute( "ISBN ", "2-3631-4 ");//设置该节点ISBN属性
XmlElement xesub1=xmlDoc.CreateElement( "title ");
xesub1.InnerText= "CS从入门到精通 ";//设置文本节点
xe1.AppendChild(xesub1);//添加到 <book> 节点中
XmlElement xesub2=xmlDoc.CreateElement( "author ");
xesub2.InnerText= "候捷 ";
xe1.AppendChild(xesub2);
XmlElement xesub3=xmlDoc.CreateElement( "price ");
xesub3.InnerText= "58.3 ";
xe1.AppendChild(xesub3);
root.AppendChild(xe1);//添加到 <bookstore> 节点中
xmlDoc.Save( "bookstore.xml ");
结果为：
<?xml version= "1.0 " encoding= "gb2312 "?>
<bookstore>
<book genre= "fantasy " ISBN= "2-3631-4 ">
<title> Oberon 's Legacy </title>
<author> Corets, Eva </author>
<price> 5.95 </price>
</book>
<book genre= "李赞红 " ISBN= "2-3631-4 ">
<title> CS从入门到精通 </title>
<author> 候捷 </author>
<price> 58.3 </price>
</book>
</bookstore>
