Creating an XML document
The .NET gives us flexibility to work with the XML files easily. .NET provides following five namespaces for XML manipulation.
1. System.Xml:- Contains major XML classes.This namespace contains many classes to read and write XML documents.Some classes under this namespace are XmlReader, XmlTextReader, XmlValidatingReader, XmlNodeReader, XmlWriter, and XmlTextWriter.
2. System.Xml.Schema:- Contains classes which work with XML schemas. XmlSchema, XmlSchemaAll, XmlSchemaXPath, and XmlSchemaType are the classes comes under this namespace..
3. System.Xml.Serialization:- Contains classes that are used to serialize objects into XML format documents or streams.
4. System.Xml.XPath:- Contains XPath related classes to use XPath specifications. XPathDocument, XPathExression, XPathNavigator, and XPathNodeIterator classes comes under this namespace..
5. System.Xml.Xsl :- Contains classes to work with XSLT transformations.
Example: Demonstrate Creation of XML Document
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Xml;
namespace _CSharpApplication
{
public partial class Form10 : Form
{
public Form10()
{
InitializeComponent();
}
private void button1_Click( object sender, EventArgs e)
{
XmlDocument xmldoc;
XmlNode xmlnode;
XmlElement xmlelem;
XmlElement xmlelem2;
XmlElement xmlelem3;
XmlText xmltext;
xmldoc= new XmlDocument ();
//XML DECLARATION SECTION
xmlnode=xmldoc.CreateNode( XmlNodeType .XmlDeclaration, "" , "" );
xmldoc.AppendChild(xmlnode);
//STARTING NODE
xmlelem=xmldoc.CreateElement( "" ,txtRoot.Text, "" );
xmltext=xmldoc.CreateTextNode(txtRootDesc.Text);
xmlelem.AppendChild(xmltext);
xmldoc.AppendChild(xmlelem);
//ADD CHILD ELEMENT TO THIS NODE
xmlelem2=xmldoc.CreateElement( "" ,txtFirstChild.Text, "" );
xmltext=xmldoc.CreateTextNode(txtFirstChildDesc.Text);
xmlelem2.AppendChild(xmltext);
xmldoc.ChildNodes.Item(1).AppendChild(xmlelem2);
//ADD CHILD ELEMENT TO THIS NODE
xmlelem3 = xmldoc.CreateElement( "" ,txtSecondChild.Text, "" );
xmltext = xmldoc.CreateTextNode(txtSecondChildDesc.Text);
xmlelem3.AppendChild(xmltext);
xmldoc.ChildNodes.Item(1).AppendChild(xmlelem3);
//SAVE THE XML DOCUMENT IN A FILE "C:\CREATEXML.XML"
try {
xmldoc.Save( "c:\\CREATEXMLDocument.xml" );
} catch ( Exception ex) {
Console.WriteLine(ex.Source);
}
MessageBox.Show( "***********XML DOCUMENT CREATED************" );
}
}
}
Thank you Raj Krishna for giving this code snippet which is very usefull for our project specially I'm searching such type of project.
