Asp.NET Xml 初试

XmlDocument doc = new XmlDocument();



            //SelectSIngleNote and SelectNodes

            doc.Load("data.xml");

            XmlNodeList xnlist = doc.SelectNodes("books/book");

            foreach (XmlNode xn in xnlist)

            {

                Console.WriteLine(xn.OuterXml);

                XmlNode titleNode = xn.SelectSingleNode("title");

                Console.WriteLine(xn.InnerText);

                Console.WriteLine("  ");

            }



            //Add xmlNode Attribute and get attributorNote

            doc.Load("data5.xml");

            XmlNodeList xn1list = doc.SelectNodes("books/book");

            foreach (  XmlNode xn   in xn1list)

                XmlAttribute xmlAttr = doc.CreateAttribute("Author");

                xmlAttr.Value = "Gzh4455";

                xn.Attributes.Append(xmlAttr);

            }

            doc.Save("data5.xml");

            Console.ReadKey();



            //LoadXml and CreateNode and save xmldocument

            doc.LoadXml("<book><title>Morning</title><price>20.5</price></book>");

            XmlNode xne = doc.CreateNode("element", "pages", "");
