Writing XML File using XmlWriter

The XmlWriter and XmlTextWriter classes are defined in the System.XML namespace.

The XmlTextWriter class is derived from XmlWriter class, which represents a writer that provides fast non-cached forward-only way of generating XML documents based on  the W3C Extensible Markup Language (XML) 1.0 specification.

In this article, I will show you how to use XmlTextWriter class to create an XML document and write data to the document.

Adding namespace Reference

Since Xml classes are defined in the System.XML namespace, so first thing you need to do is to Add the System.XML reference to the project.

using

 

The constructor of the XmlTextWriter class creates an XML file if file doesn't exist. In this sample, I create a new XML file called xmltest.xml in C/temp directory.

XmlTextWriter writer =

 

XmlTextWriter writer = new XmlTextWriter(Console.Out);

 

The WriteStartDocument method starts a new document. The WriteStartElement and the WriteEndElement pair is used to add a new element to the document. The WriteString writes a string to the document.

writer.WriteStartDocument(); writer.WriteComment("Commentss: XmlWriter Test Program"); writer.WriteProcessingInstruction("Instruction","Person Record"); writer.WriteStartElement("p", "person", "urn:person"); writer.WriteStartElement("LastName",""); writer.WriteString("Chand"); writer.WriteEndElement(); writer.WriteElementInt16("age","", 25); writer.WriteEndDocument();

 

namespace

{ using System;

 using System.Xml;

 /// <summary> /// Summary description for Class1. /// </summary>

public class Class1 {

   public Class1() { }

public static int Main(string[] args)

{

try

{

// Creates an XML file is not exist XmlTextWriter writer = new XmlTextWriter("C://temp//xmltest.xml", null);

// Starts a new document writer.WriteStartDocument(); //Write comments writer.WriteComment("Commentss: XmlWriter Test Program"); writer.WriteProcessingInstruction("Instruction","Person Record");

// Add elements to the file

 writer.WriteStartElement("p", "person", "urn:person");

writer.WriteStartElement("LastName","");

writer.WriteString("Chand"); writer.WriteEndElement();

writer.WriteStartElement("FirstName","");

writer.WriteString("Mahesh");

writer.WriteEndElement();

 writer.WriteElementInt16("age","", 25);

 // Ends the document

writer.WriteEndDocument();

}

catch (Exception e)

{

Console.WriteLine ("Exception: {0}", e.ToString());

}

return 0;

 }

}

}
