  • ASP.NET XML读取、增加、修改和删除操作

    C#—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);
       }
    }
