Here is small example for your question Consier following xml document on which we want to manipulate xml version = "1.0" encoding = "utf-8" ?> Class > Students > studentName > Amit studentName > studentAge > 20 studentAge > studentResult > PASS studentResult > Students > Students > studentName > Vikram studentName > studentAge > 19 studentAge > studentResult > FAIL studentResult > Students > Students > studentName > Siddhesh studentName > studentAge > 20 studentAge > studentResult > PASS studentResult > Students > Class > There are many ways we can manipulate and read the given xml document in c# 1) Using XmlDocument , XmlNode and XmlElement . You can use this classes to navigate elements of xml document systematically. public void ReadXML() { string appData = AppDomain.CurrentDomain.GetData( "DataDirectory" ).ToString(); string path = Path.Combine(appData, "XMLDemo.xml" ); XmlDocument doc = new XmlDocument(); // Require using System.Xml; doc.Load(path); XmlNodeList nodes = doc.DocumentElement.SelectNodes( "/Class/Students" ); foreach (XmlNode node in nodes) // XMLNode is Students node of class element { //fetching individual node value from Students Node var studentName = node.SelectSingleNode( "studentName" ).InnerText; var studentAge = node.SelectSingleNode( "studentAge" ).InnerText; var studentResult = node.SelectSingleNode( "studentResult" ).InnerText; } XmlElement root = doc.DocumentElement; // Will give you root xml element XmlNodeList elemList = root.GetElementsByTagName( "Students" ); // getting Students Node from XMLElement object foreach (XmlNode node in nodes) { var studentName = node.SelectSingleNode( "studentName" ).InnerText; var studentAge = node.SelectSingleNode( "studentAge" ).InnerText; var studentResult = node.SelectSingleNode( "studentResult" ).InnerText; } } In the above example i have used XmlDocument of System.Xml namespace for navigating xml elements first using SelectNodes method i have fetch XMLNodeList and iterating XMLNode for accessing all child elements . Secondly i have use XmlElement class with GetElementsByTagName to get all nodes of class. 2) Another way you can fetch documents using XElement class of System.Xml.Linq namespace following is example you can refer. public void ReadXMLElelment() { string appData = AppDomain.CurrentDomain.GetData( "DataDirectory" ).ToString(); string path = Path.Combine(appData, "XMLDemo.xml" ); XDocument doc = XDocument.Load(path); // Require using System.Xml.Linq XElement elements = doc .Element( "Class" ) .Element( "Students" ); // Navigating Students element this will result in first Students element var studentName = elements.Element( "studentName" ).Value; // getting individual elemets value from XElement object var studentAge = elements.Element( "studentAge" ).Value; var studentResult = elements.Element( "studentResult" ).Value; } I hope this is useful Regards, Ketan
