Reading XML using DataSet Class

In this article we will discuss how to read and XML File using object of DataSet Class.

Sample XML File

Employee.xml

<?xml version="1.0" ?>

 <EMPLOYEES>

 <EMP>

  <EMPNO>7369</EMPNO>

  <ENAME>SMITH</ENAME>

  <JOB>CLERK</JOB>

  <MGR>7902</MGR>

  <HIREDATE>17-DEC-80</HIREDATE>

  <SAL>800</SAL>

  </EMP>

 <EMP>

  <EMPNO>7499</EMPNO>

  <ENAME>ALLEN</ENAME>

  <JOB>SALESMAN</JOB>

  <MGR>7698</MGR>

  <HIREDATE>20-FEB-81</HIREDATE>

  <SAL>1600</SAL>

  <COMM>300</COMM>

  </EMP>

 <EMP>

  <EMPNO>7521</EMPNO>

  <ENAME>WARD</ENAME>

  <JOB>SALESMAN</JOB>

  <MGR>7698</MGR>

  <HIREDATE>22-FEB-81</HIREDATE>

  <SAL>1250</SAL>

  <COMM>500</COMM>

  </EMP>

 <EMP>

  <EMPNO>7566</EMPNO>

  <ENAME>JONES</ENAME>

  <JOB>MANAGER</JOB>

  <MGR>7839</MGR>

  <HIREDATE>02-APR-81</HIREDATE>

  <SAL>2975</SAL>

  </EMP>

 <EMP>

  <EMPNO>7654</EMPNO>

  <ENAME>MARTIN</ENAME>

  <JOB>SALESMAN</JOB>

  <MGR>7698</MGR>

  <HIREDATE>28-SEP-81</HIREDATE>

  <SAL>1250</SAL>

  <COMM>1400</COMM>

  </EMP>

  </EMPLOYEES>

Snippet to read the XML File

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

 

namespace Reading_XML_Data

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

 

        private void Form1_Load(object sender, EventArgs e)

        {

            DataSet ds = new DataSet();

            ds.ReadXml(@"D:\Employee.xml");

            foreach (DataRow dr in ds.Tables["EMP"].Rows)

            {

                MessageBox.Show("Employee ID: " + dr["EMPNO"] +  " Name: " + dr["ENAME"]);

            }

        }

    }

}

 

Here,

 DataSet ds = new DataSet();

We create an instance of DataSet Class

ds.ReadXml(@"D:\Employee.xml");

The ReadXml method of DataSet class is used to read XML data from the File Specified here (Employee.xml) and Load it to the DataSet.

The parameter to the ReadXml method is the Location of Employee.xml File

foreach (DataRow dr in ds.Tables["EMP"].Rows)

            {

                MessageBox.Show("Employee ID: " + dr["EMPNO"] +

                  " Name: " + dr["ENAME"]);

            }

Here we read the rows from the dataset using DataRow class and looping through the rows in the DataSet ds.

Hope this might help you a little.
