asp.net C#操作xml文檔實現代碼

代碼如下

複製代碼

XmlDocument xmldoc = new XmlDocument();             //在XML的文檔的最頭部加入XML的聲明段落             XmlNode xmlnode = xmldoc.CreateNode(XmlNodeType.XmlDeclaration, "", "");             xmldoc.AppendChild(xmlnode);             //建立根節點             XmlElement root = xmldoc.CreateElement("root");             root.InnerText = "我是根節點";             xmldoc.AppendChild(root);             xmldoc.Save(@"D:My DocumentsVisual Studio 2010ProjectsWebApplication2WebApplication2test.xml");

產生的xml是這樣的

代碼如下	複製代碼
<?xml version="1.0"?>  <root>我是根節點</root>

另外一種建立建立xml的方法

代碼如下	複製代碼
XmlDocument xmldoc = new XmlDocument();             xmldoc.LoadXml(             "<?xml version="1.0" encoding="utf-8" ?>" +             "<root>我是根節點</root>"                );             xmldoc.Save(@"D:My DocumentsVisual Studio 2010ProjectsWebApplication2WebApplication2test.xml");

讀取xml

xml如下

代碼如下

<?xml version="1.0" encoding="utf-8"?> <root id="root">     <list num="0">         <name type="string">minglecun</name>         <age type="number">55</age>     </list>     <list num="1">         <name type="string">huluwa</name>         <age type="number">1</age>     </list> </root> XmlDocument xmldoc = new XmlDocument();             xmldoc.Load(@"D:My DocumentsVisual Studio 2010ProjectsWebApplication2WebApplication2test.xml");             //讀某個節點             XmlNode xmlnode = xmldoc.SelectSingleNode("//root");             Console.WriteLine(xmlnode.InnerXml);             Console.WriteLine("------------------------------------------------");             XmlNode xmlnode1 = xmldoc.SelectSingleNode("//root//list");             Console.WriteLine(xmlnode1.InnerXml);             Console.WriteLine("------------------------------------------------");             //             XmlNodeList xn0 = xmldoc.SelectSingleNode("//root").ChildNodes;             foreach (XmlNode node in xn0)             {                 Console.WriteLine("========"+node.Name);             }
