ASP.NET XML读取、增加、修改和删除操作
1.xml文件格式如下：
<?xml version="1.0" encoding="utf-8"?><projects><project name="PlatformFramewo" vss-path="Platform$/Source CodHdt$Pla~1.sln" /></projects>
1.读取
DataSet ds = new DataSet();ds.ReadXml(Server.MapPath(@"Projects.xml"));DataTable dt = ds.Tables[0];return dt;//得到的datable在前台进行循环输出，省略...<tr style="font-weight: bold;"> //文字加粗<td style="border-bottom: solid 2px gray;"> //文字底部加横线
2.新增
XmlDocument xmlDoc = new XmlDocument();string Path = Server.MapPath(@"Projects.xml");xmlDoc.Load(Path);XmlNode root=xmlDoc.SelectSingleNode("projects");XmlElement xe1 = xmlDoc.CreateElement("project");xe1.SetAttribute("name", txtProjectName.Text);strVssPath = txtProjectVss.Text + "$" + txtProjectPath.Text + "$" + txtProjectSln.Text;xe1.SetAttribute("vss-path",strVssPath);root.AppendChild(xe1);xmlDoc.Save(Path);3.修改
XmlDocument xmlDoc = new XmlDocument();string Path = Server.MapPath(@"Projects.xml");xmlDoc.Load(Path);XmlNodeList nodelist = xmlDoc.SelectSingleNode("projects").ChildNodes;foreach (XmlNode xn in nodelist){ XmlElement xe = (XmlElement)xn; if (xe.GetAttribute("name") == Request["name"].ToString()) { xe.SetAttribute("name", txtProjectName1.Text); strVssPath = txtProjectVss1.Text + "$" + txtProjectPath1.Text + "$" + txtProjectSln1.Text; xe.SetAttribute("vss-path", strVssPath); xmlDoc.Save(Path); } }4.删除
XmlDocument xmlDoc = new XmlDocument();string Path = Server.MapPath(@"Projects.xml");xmlDoc.Load(Path);XmlNodeList nodelist = xmlDoc.SelectSingleNode("projects").ChildNodes;foreach (XmlNode xn in nodelist){ XmlElement xe = (XmlElement)xn; if (xe.GetAttribute("name") == Request["name"].ToString()) { xn.ParentNode.RemoveChild(xn); xmlDoc.Save(Path); }}
