Příklady

Následující příklad zobrazuje informace o zápisech deklarovaných v dokumentu XML.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
void DisplayNotations( XmlNamedNodeMap^ nMap )
{
   for ( int i = 0; i < nMap->Count; i++ )
   {
      XmlNotation^ note = dynamic_cast<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();

   }
}

int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->Load( "doment.xml" );
   Console::WriteLine( "Display information on all notations..." );
   XmlNamedNodeMap^ nMap = doc->DocumentType->Notations;
   DisplayNotations( nMap );
}

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

Příklad používá soubor doment.xml jako vstup.

<!DOCTYPE doc [

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

  <!NOTATION jpg PUBLIC "Jpeg picture format">
  <!NOTATION gif SYSTEM "Gif picture format">

  <!ENTITY wn PUBLIC "http://www.cohowinery.com" "coho.exe" NDATA w>
  <!ENTITY vn SYSTEM "http://www.cohovineyard.com" NDATA v>
  <!ENTITY mytxt "Text Sample">
