<source lang="csharp"> using System; using System.IO; using System.Linq; using System.Collections; using System.Collections.Generic; using System.Xml; using System.Xml.XPath; using System.Xml.Schema; 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")))); XElement bookParticipant = xDocument.XPathSelectElement("//Books/Book[FirstName="A"]"); Console.WriteLine(bookParticipant); }
}

<source lang="csharp"> 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", "J"), new XElement("LastName", "R")), new XElement("Book", new XAttribute("type", "Author"), new XElement("FirstName", "E"), new XElement("LastName", "B")))); 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 (XElement element in elements.ToArray()) { Console.WriteLine("Removing {0}= {1} ¡�", element.Name, element.Value); element.Remove(); } Console.WriteLine(xDocument); }
