- <bookstore>

- <book genre="autobiography" publicationdate="1991" ISBN="1-861003-11-0">  <title>The Autobiography of Benjamin Franklin</title> - <author>  <first-name>Benjamin</first-name>   <last-name>Franklin</last-name>   </author>  <price>8.99</price>   </book>- <book genre="novel" publicationdate="1967" ISBN="0-201-63361-2">  <title>The Confidence Man</title> - <author>  <first-name>Herman</first-name>   <last-name>Melville</last-name>   </author>  <price>11.99</price>   </book>- <book genre="philosophy" publicationdate="1991" ISBN="1-861001-57-6">  <title>The Gorgias</title> - <author>  <name>Plato</name>   </author>  <price>9.99</price>   </book>  </bookstore>

 doc.Load("..//books.xml");

1)得到节点<title>清单！  //get only the nodes that we want.      XmlNodeList nodeLst=doc.GetElementsByTagName("title");也可以       XmlNodeList nodeLst=doc.SelectNodes("/bookstore/book/title");

      //iterate through the XmlNodeList

      foreach(XmlNode node in nodeLst)        listBox1.Items.Add(node.InnerText);

2）增加节点

    //create the declaration section      XmlDeclaration newDec=doc.CreateXmlDeclaration("1.0",null,null);      doc.AppendChild(newDec);      //create the new root element      XmlElement newRoot=doc.CreateElement("newBookstore");      doc.AppendChild(newRoot);   XmlElement newBook=doc.CreateElement("book");      //set some attributes      newBook.SetAttribute("genre","Mystery");      newBook.SetAttribute("publicationdate","2001");      newBook.SetAttribute("ISBN","123456789");      //create a new 'title' element      XmlElement newTitle=doc.CreateElement("title");      newTitle.InnerText="Case of the Missing Cookie";      newBook.AppendChild(newTitle);      doc.DocumentElement.AppendChild(newBook);

3）  查找

 string srch="Bookstore/book[title='" + listBox1.SelectedItem.ToString() + "']";

      XmlNode foundNode=doc.SelectSingleNode(srch);      if(foundNode!=null)        MessageBox.Show(foundNode.InnerText);      else        MessageBox.Show("Not found");     

==================

根据属性查找:

 XmlNode nodeQ = xmlDoc.SelectSingleNode("/BookStore");

 XmlNode node = nodeQ.SelectSingleNode("book[@publicationdate='" + sName + "']");

点到其它节点value:

sISBN = node.Attributes["ISBN"].Value
