XML LINQ
Accessing the First Child Element with a Specified Name
using System; using System.Linq; using System.Collections; using System.Collections.Generic; using System.Xml; using System.Xml.Linq; public class MainClass { public static void Main() { XElement firstParticipant; XDocument xDocument = new XDocument(new XDeclaration("1.0", "UTF-8", "yes"), new XDocumentType("Books", null, "Books.dtd", null), new XProcessingInstruction("Book", "out-of-print"), new XElement("Books", firstParticipant = new XElement("Book", new XComment("This is a new author."), new XProcessingInstruction("AuthorHandler", "new"), new XAttribute("type", "Author"), new XElement("FirstName", "J"), new XElement("LastName", "R")), new XElement("Book", new XAttribute("type", "Author"), new XElement("FirstName", "E"), new XElement("LastName", "B")))); Console.WriteLine(firstParticipant.Element("FirstName")); } }
FirstNode and LastNode give you direct access to the first or last child node
using System; using System.Collections.Generic; using System.Linq; using System.Xml.Linq; public class MainClass { public static void Main() { var bench = new XElement("bench", new XElement("t", new XElement("B", "H"), new XElement("A", "R") ), new XElement("t", new XElement("B", "S"), new XElement("A", "N") ), new XComment("This is the comment") ); foreach (XNode node in bench.Nodes()) Console.WriteLine(node.ToString(SaveOptions.DisableFormatting) + "."); } }
Accessing Named Child Elements Using the Elements Method

Accessing an Element's Child Elements Using the Elements Method
using System; using System.Linq; using System.Collections; using System.Collections.Generic; using System.Xml; using System.Xml.Linq; public class MainClass { public static void Main() { XElement firstParticipant; XDocument xDocument = new XDocument( new XDeclaration("1.0", "UTF-8", "yes"), new XDocumentType("Books", null, "Books.dtd", null), new XProcessingInstruction("Book", "out-of-print"), new XElement("Books", firstParticipant = new XElement("Book", new XComment("This is a new author."), new XProcessingInstruction("AuthorHandler", "new"), new XAttribute("type", "Author"), new XElement("FirstName", "J"), new XElement("LastName", "R")), new XElement("Book", new XAttribute("type", "Author"), new XElement("FirstName", "E"), new XElement("LastName", "B")))); foreach (XNode node in firstParticipant.Elements()) { Console.WriteLine(node); } } }
Calling the Second Attributes Prototype
using System; using System.Linq; using System.Collections; using System.Collections.Generic; using System.Xml; using System.Xml.Linq; public class MainClass { public static void Main() { XDocument xDocument = new XDocument( new XElement("Books", new XElement("Book", new XAttribute("type", "Author"), new XElement("FirstName", "A"), new XElement("LastName", "B")), new XElement("Book", new XAttribute("type", "Author"), new XElement("FirstName", "C"), new XElement("LastName", "D")))); IEnumerable<XElement> elements = xDocument.Element("Books").Elements("Book"); foreach (XElement element in elements) { Console.WriteLine("Source element: {0} : value = {1}", element.Name, element.Value); } foreach (XAttribute attribute in elements.Attributes("type")) { Console.WriteLine("Attribute: {0} : value = {1}", attribute.Name, attribute.Value); } } }
