LoadXml

A Simple XML Example
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() { XmlElement xmlBook; XmlAttribute xmlParticipantType; XmlElement xmlFirstName; XmlElement xmlLastName; XmlDocument xmlDoc = new XmlDocument(); XmlElement xmlBooks = xmlDoc.CreateElement("Books"); xmlDoc.AppendChild(xmlBooks); xmlBook = xmlDoc.CreateElement("Book"); xmlParticipantType = xmlDoc.CreateAttribute("type"); xmlParticipantType.InnerText = "Author"; xmlBook.Attributes.Append(xmlParticipantType); xmlFirstName = xmlDoc.CreateElement("FirstName"); xmlFirstName.InnerText = "J"; xmlBook.AppendChild(xmlFirstName); xmlLastName = xmlDoc.CreateElement("LastName"); xmlLastName.InnerText = "R"; xmlBook.AppendChild(xmlLastName); xmlBooks.AppendChild(xmlBook); xmlBook = xmlDoc.CreateElement("Book"); xmlParticipantType = xmlDoc.CreateAttribute("type"); xmlParticipantType.InnerText = "Author"; xmlBook.Attributes.Append(xmlParticipantType); xmlFirstName = xmlDoc.CreateElement("FirstName"); xmlFirstName.InnerText = "E"; xmlBook.AppendChild(xmlFirstName); xmlLastName = xmlDoc.CreateElement("LastName"); xmlLastName.InnerText = "B"; xmlBook.AppendChild(xmlLastName); xmlBooks.AppendChild(xmlBook); XmlNodeList authorsList = xmlDoc.SelectNodes("Books/Book[@type="Author"]"); foreach (XmlNode node in authorsList) { XmlNode firstName = node.SelectSingleNode("FirstName"); XmlNode lastName = node.SelectSingleNode("LastName"); Console.WriteLine("{0} {1}", firstName, lastName); } } }
XML Write: comment, start element, end element, attribute
using System; using System.Xml; public class TestXMLWriter{ static void Main(string[] args) { XmlTextWriter writer = new XmlTextWriter("test.xml", new System.Text.ASCIIEncoding()); writer.Formatting = Formatting.Indented; writer.Indentation = 4; writer.WriteStartDocument(); writer.WriteComment("Comment"); writer.WriteStartElement("ElementName", "myns"); writer.WriteStartAttribute("prefix", "attrName", "myns"); writer.WriteEndAttribute(); writer.WriteElementString("ElementName", "myns", "value"); writer.WriteEndElement(); writer.WriteEndDocument(); writer.Flush(); writer.Close(); } }
Write XML document to console
using System; using System.Xml; public class HelloXML { public static void Main(string [] args) { XmlTextWriter writer = new XmlTextWriter(Console.Out); writer.WriteStartDocument( ); writer.WriteElementString("www.kutayzorlu.com/java2s/com", "XML"); writer.WriteEndDocument( ); writer.Close( ); } }
