Exempel

I följande exempel visas information om de entiteter som deklarerats i XML-dokumentet.

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 entities...");
     XmlNamedNodeMap nMap = doc.DocumentType.Entities;
     DisplayEntities(nMap);
  }

  public static void DisplayEntities(XmlNamedNodeMap nMap)
  {
     for (int i=0; i < nMap.Count; i++)
     {
        XmlEntity ent = (XmlEntity) nMap.Item(i);
        Console.Write("{0} ", ent.NodeType);
        Console.Write("{0} ", ent.Name);
        Console.Write("{0} ", ent.NotationName);
        Console.Write("{0} ", ent.PublicId);
        Console.Write("{0} ", ent.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 entities...")     
     Dim nMap as XmlNamedNodeMap = doc.DocumentType.Entities
     DisplayEntities(nMap)
  end sub
 
  public shared sub DisplayEntities(nMap as XmlNamedNodeMap)
     Dim i as integer   
     for i = 0 to nMap.Count - 1
        Dim ent as XmlEntity = CType(nMap.Item(i), XmlEntity)
        Console.Write("{0} ", ent.NodeType)
        Console.Write("{0} ", ent.Name)
        Console.Write("{0} ", ent.NotationName)
        Console.Write("{0} ", ent.PublicId)
        Console.Write("{0} ", ent.SystemId)
        Console.WriteLine()
     next
  end sub
end class

I exemplet används filen doment.xml som indata.

<!DOCTYPE doc [

  <!ELEMENT doc ANY>
 
  <!NOTATION w SYSTEM "wine.exe">
  <!NOTATION v PUBLIC "vine.exe">

  <!NOTATION jpg PUBLIC "Jpeg picture format">

Kommentarer

Ordningen i vilken entiteterna returneras baseras inte på i vilken ordning dessa objekt kan visas i dokumentet. Ordern garanteras inte heller vara densamma mellan liknande dokument eller mellan olika implementeringar eller versioner av klassen.
