XmlNotation.SystemId Property

Gets the value of the system identifier on the notation declaration.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public string SystemId { get; }

Property Value

Type: System.String
The system identifier on the notation. If there is no system identifier, null is returned.

The following example displays information on the notations declared in the 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();
    }
  }            
}
#using <mscorlib.dll>
#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(S" {0} ", __box(note -> NodeType));
      Console::Write(S" {0} ", note -> Name);
      Console::Write(S" {0} ", note -> PublicId);
      Console::Write(S" {0} ", note -> SystemId);
      Console::WriteLine();
   }
}            

int main() 
{
   XmlDocument* doc = new XmlDocument();
   doc -> Load(S"doment.xml");

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

The example uses the file doment.xml as input.
