Introduction:

Xml stands for Extensible Markup Language. All the Tags/Elements of Xml are user defined that’s why it is Easy to Create and understand.

Important:

To Create XML we have used following Class and Methods. XmlDocumant class is present under System.Xml namespace.

Classes:

  • XmlDocument
  • XmlDeclaration
  • XmlElement

Methods:

  • CreateElement()
  • AppendChild()

Example:

In Example, we have Created XML having 2 Element Id & Name using Windows Application.

Open Visual Studio and Design a form like this:



Add Following Codes on “Save” Button_click :

  1. namespace Xml_Proc
  2. {
  3. public partial class Form1 : Form
  4. {
  5. public Form1()
  6. {
  7. InitializeComponent();
  8. }
  9. private XmlElement root;
  10. public string path = @"C:\Users\kundan\Desktop\Sample.xml";
  11. XmlDocument doc = new XmlDocument();
  13. private void button1_Click(object sender, EventArgs e)
  14. {
  15. if (!File.Exists(path))
  16. {
  17. XmlDeclaration declaration = doc.CreateXmlDeclaration("1.0", "UTF-8", "yes");
  18. root = doc.CreateElement("Employee");
  19. XmlElement Emp = doc.CreateElement("Emp");
  20. XmlElement ID = doc.CreateElement("ID");
  21. XmlElement NAME = doc.CreateElement("NAME");
  23. ID.InnerText = textBox1.Text;
  24. NAME.InnerText = textBox2.Text;
  26. doc.AppendChild(declaration);
  27. doc.AppendChild(root);
  28. root.AppendChild(Emp);
  29. Emp.AppendChild(ID);
  30. Emp.AppendChild(NAME);
  32. doc.Save(path);
  34. MessageBox.Show("XML Created && Data has been Inserted");
  35. }
  36. else
  37. {
  38. doc = new XmlDocument();
  39. doc.Load(path);
  40. root = doc.DocumentElement;
  41. XmlElement Emp = doc.CreateElement("Emp");
  42. XmlElement ID = doc.CreateElement("ID");
  43. XmlElement NAME = doc.CreateElement("NAME");
  44. ID.InnerText = textBox1.Text;
  45. NAME.InnerText = textBox2.Text;
  46. Emp.AppendChild(ID);
  47. Emp.AppendChild(NAME);
  48. root.AppendChild(Emp);
  49. doc.Save(path);
  50. MessageBox.Show("XML Updated");
  51. }
  52. }
  53. }
  54. }
Output will look like:
