code for XML in c# to read node and values

Question

I have to compare two files in XML, where in i need to display the contents of the "unmatched pattern between the files, whether it be a difference in name of a node or values of node.

code so far i have written is

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

namespace ConsoleApplication1
{
   public class Program
    {
        public Program()
        {

            XmlDocument _mxml1 = new XmlDocument();

            _mxml1.Load(@"C:\Users\Rahul\Documents\xml work\abcd.xml");

            XmlDocument _mxml2 = new XmlDocument();

            _mxml2.Load(@"C:\Users\Rahul\Documents\xml work\efg.xml");


            XmlElement _melement1 = _mxml1.DocumentElement;

            XmlElement _melement2 = _mxml2.DocumentElement;


            XPathNavigator nav1 = _mxml1.CreateNavigator();

            XPathNavigator nav2 = _mxml2.CreateNavigator();

            if (_melement1.HasChildNodes && _melement2.HasChildNodes && _melement1.ChildNodes.Count == _melement2.ChildNodes.Count)
            {

                XmlNodeList _node1 = _melement1.ChildNodes;

                XmlNodeList _node2 = _melement2.ChildNodes;

                foreach (XmlNode _n1 in _node1)
                {

                    foreach (XmlNode _n2 in _node2)
                    {

                        int count = _n1.ChildNodes.Count;

                        int count2 = _n2.ChildNodes.Count;


                        if (_n1.Name.ToString() == _n2.Name.ToString())
                        {

                            int res = _n1.OuterXml.CompareTo(_n2.OuterXml);

                            if (res == 1)
                            {

                                Console.WriteLine("All the child names match for the case ");

                            }

                            if (_n1.InnerText.ToString() != _n2.InnerText.ToString())
                            {



                                Console.WriteLine("Values of some child doesnot match");



                                // here we need to traverse through child nodes of both xmls to find out the change in file..



                            }

                            if (_n1.InnerXml.ToString() == _n2.InnerXml.ToString())
                            {

                                Console.WriteLine("Records match completly");


                            }


                        }

                        else
                        {

                            Console.WriteLine("XML_1 " + "     " + "" + "XML_2  \n" + _n1.Name + " " + _n2.Name);

                        }

                    }

                }

            }


        }
        static void Main(string[] args)
        {
            Program obj = new Program();
        }
    }
}

now the problem is if there is difference in value of a node how can find that portion of string which is different in two files...

Have you considered formatting your code and removing empty lines? — Sergey Berezovskiy, Mar 17 '13 at 13:40
