XmlNotation.SystemId Eigenschap

public:
 property System::String ^ SystemId { System::String ^ get(); };

public string? SystemId { get; }

public string SystemId { get; }

member this.SystemId : string

Public ReadOnly Property SystemId As String

Waarde van eigenschap

De systeem-id voor de notatie. Als er geen systeem-id is, null wordt deze geretourneerd.

Voorbeelden

In het volgende voorbeeld ziet u informatie over de notaties die zijn gedeclareerd in het XML-document.

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

In het voorbeeld wordt het bestand doment.xml als invoer gebruikt.

<!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">

  <!ATTLIST doc 
        src     ENTITY         #IMPLIED
        srcs    ENTITIES       #IMPLIED
