ASP.NET
Code using C#:
After designing the webpage, write the following code
in code behind file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Xml;
using System.Data;
public partial class
XML : System.Web.UI.Page
{
protected void
Page_Load(object sender, EventArgs e)
{
}
protected void
Button1_Click(object sender, EventArgs e)
{
XmlDocument
xmldoc = new XmlDocument();
xmldoc.Load(Server.MapPath("XMLFile.xml"));
XmlElement
Testing = xmldoc.CreateElement("Testing");
XmlElement
name = xmldoc.CreateElement("Name");
name.InnerText = TextBox1.Text;
XmlElement
age = xmldoc.CreateElement("Age");
age.InnerText = TextBox2.Text;
XmlElement
department = xmldoc.CreateElement("department");
department.InnerText = TextBox3.Text;
XmlElement
salary = xmldoc.CreateElement("salary");
salary.InnerText = TextBox4.Text;
Testing.AppendChild(name);
Testing.AppendChild(age);
Testing.AppendChild(department);
Testing.AppendChild(salary);
xmldoc.DocumentElement.AppendChild(Testing);
xmldoc.Save(Server.MapPath("XMLFile.xml"));
bindlist();
}
public void
bindlist()
{
XmlTextReader
xmlreader = new XmlTextReader(Server.MapPath("XMLFile.xml"));
DataSet
ds = new DataSet();
ds.ReadXml(xmlreader);
xmlreader.Close();
if
(ds.Tables[0].Rows.Count > 0)
{
DataList1.DataSource = ds;
DataList1.DataBind();
}
