Contoh berikut menampilkan informasi tentang notasi yang dideklarasikan dalam dokumen XML.

using System;
using System.IO;
using System.Xml;

public class Sample
{
  private const String filename = "doment.xml";

  public static void Main()
  {
    XmlDocument doc = new XmlDocument();
    doc.Load(filename);

    Console.WriteLine("Display information on all notations...");
    XmlNamedNodeMap nMap = doc.DocumentType.Notations;
    DisplayNotations(nMap);
  }

  public static void DisplayNotations(XmlNamedNodeMap nMap)
  {
     for (int i=0; i < nMap.Count; i++)
     {
        XmlNotation note = (XmlNotation) nMap.Item(i);
        Console.Write("{0} ", note.NodeType);
        Console.Write("{0} ", note.Name);
        Console.Write("{0} ", note.PublicId);
        Console.Write("{0} ", note.SystemId);
        Console.WriteLine();
    }
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  private const filename as String = "doment.xml"
 
  public shared sub Main()
    Dim doc as XmlDocument = new XmlDocument()
    doc.Load(filename)

    Console.WriteLine("Display information on all notations...")     
    Dim nMap as XmlNamedNodeMap = doc.DocumentType.Notations
    DisplayNotations(nMap)      
  end sub
 
  public shared sub DisplayNotations(nMap as XmlNamedNodeMap)
     Dim i as integer   
     for i = 0 to nMap.Count - 1
        Dim note as XmlNotation = CType(nMap.Item(i), XmlNotation)
        Console.Write("{0} ", note.NodeType)
        Console.Write("{0} ", note.Name)
        Console.Write("{0} ", note.PublicId)
        Console.Write("{0} ", note.SystemId)
        Console.WriteLine()
     next
  end sub            
end class

Contohnya menggunakan file doment.xml sebagai input.
