Extensible Markup Language (XML) is a markup laguage that defines a set of rules for encoding documents in a format that is both human readable and machine readable.

You can Make your own XML file and integrate with your Dataset or Datatable as per your Requirement. Here I am writing some steps, after follow this step you can integrate your XML file.

1. first create a test.xml file like this given code

<?xml version="1.0" encoding="utf-8" ?>
<HrSolution>
  <HrEmployee>
    <EmployeeID>123</EmployeeID>
    <EmployeeName>Nirja</EmployeeName>
    <EmployeeSalary>19000</EmployeeSalary>
    <EmployeeAddress>Address</EmployeeAddress>
  </HrEmployee>
  <HrEmployee>
    <EmployeeID>124</EmployeeID>
    <EmployeeName>Priya</EmployeeName>
    <EmployeeSalary>20000</EmployeeSalary>
    <EmployeeAddress>Address</EmployeeAddress>
  </HrEmployee>
  <HrEmployee>
    <EmployeeID>125</EmployeeID>
    <EmployeeName>Deepika</EmployeeName>
    <EmployeeSalary>12000</EmployeeSalary>
    <EmployeeAddress>Address</EmployeeAddress>
  </HrEmployee>
  <HrEmployee>
    <EmployeeID>126</EmployeeID>
    <EmployeeName>Gayatri</EmployeeName>
    <EmployeeSalary>22000</EmployeeSalary>
    <EmployeeAddress>Address</EmployeeAddress>
  </HrEmployee>
  <HrEmployee>
    <EmployeeID>127</EmployeeID>
    <EmployeeName>Ramesh</EmployeeName>

         //XML read by Dataset
        ds.ReadXml(Request.MapPath("test.xml"));

        //Show xml contents to the GridView
        GridView1.DataSource = ds.Tables[0];
        GridView1.DataBind();
