二度Xml<2>

一下介绍xml的基本操作，添加xml新节点；

其他方法在前一篇日记中有详细讲解，请详见：http://www.cnblogs.com/fjsnail/archive/2012/10/20/2732127.html

        public void addElementText()
        {
            XmlDocument xmldoc = new XmlDocument();
            xmldoc.Load("../../testXml1.xml");

            //get the root element
            XmlElement root = xmldoc.DocumentElement;

            //create new nodes
            XmlElement newbook=xmldoc.CreateElement("book");

            XmlElement newTitle = xmldoc.CreateElement("Title");
            XmlElement newAuthor = xmldoc.CreateElement("author");
            XmlElement newCode = xmldoc.CreateElement("code");

            XmlText titleText = xmldoc.CreateTextNode("how to learn C#2");
            XmlText AuthorText = xmldoc.CreateTextNode("xianyun");
            XmlText codeText = xmldoc.CreateTextNode("3543453");

            XmlComment comment = xmldoc.CreateComment("nimeimeiede");
            XmlAttribute attrubute = xmldoc.CreateAttribute("ha");
                                                                          这里，我觉得用之前那种方法更简单

                                                                          newTitle.innerText(“nihao”);
            //insert the elements
            newbook.AppendChild(newTitle);
            newbook.AppendChild(newAuthor);
            newbook.AppendChild(newCode);

            newbook.AppendChild(comment);

            newTitle.AppendChild(titleText);
            newTitle.AppendChild(attrubute);
            newAuthor.AppendChild(AuthorText);
            newCode.AppendChild(codeText);

            root.InsertAfter(newbook, root.LastChild);
            xmldoc.Save("../../testXml1.xml");

        }
