XML FILE Opening and Reading using C#.NET or ASP.NET

In the previous example we have created the XML file using C#.NET. Now we are going to read that XML file based on required tag. In the below program we are giving  XML file as input and we will open XML file. We will read the  XML  node values from the  XML file and showing on the screen.

Input to the program. 



Output from the program:

Program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.IO;

namespace XMLFILEREADING
{
    class Program
    {
        static void Main(string[] args)
        {
            //Declarations
            string str = null;
            string filePath = "c://customer.xml";
            XmlDataDocument xmlDocument = new XmlDataDocument();
            XmlNodeList xmlNodeListData;

            //open xml file using IO operation filestream.
            FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read);

            //loading xml document
            xmlDocument.Load(fs);

            //getting xml tag data. 
            xmlNodeListData = xmlDocument.GetElementsByTagName("Customer");

            //looping all internal nodes of the customer tag
            for (int iIndex = 0; iIndex <= xmlNodeListData.Count - 1; iIndex++)
            {
                str = xmlNodeListData[iIndex].ChildNodes.Item(0).InnerText.Trim() + " ---> " + xmlNodeListData[iIndex].ChildNodes.Item(1).InnerText.Trim(); 
                Console.WriteLine(str);
            }
            Console.ReadLine();
        }
    }
}
