Mendapatkan kumpulan XmlEntity simpul yang dideklarasikan dalam deklarasi jenis dokumen.

public:
 property System::Xml::XmlNamedNodeMap ^ Entities { System::Xml::XmlNamedNodeMap ^ get(); };

public System.Xml.XmlNamedNodeMap Entities { get; }

member this.Entities : System.Xml.XmlNamedNodeMap

Public ReadOnly Property Entities As XmlNamedNodeMap

Nilai Properti

XmlNamedNodeMap

Yang XmlNamedNodeMap berisi simpul XmlEntity . Yang dikembalikan XmlNamedNodeMap bersifat baca-saja.

Contoh

Contoh berikut menampilkan informasi tentang entitas 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 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

Contohnya menggunakan file doment.xml sebagai input.

<!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
        jpgPic  NOTATION (jpg) #IMPLIED
        gifPic  NOTATION (gif) #REQUIRED>
]>

<doc jpgPic="jpg" gifPic="gif" srcs="vn wn">
    something
</doc>

Keterangan

Urutan di mana entitas dikembalikan tidak didasarkan pada urutan item ini mungkin muncul dalam dokumen. Urutannya juga tidak dijamin sama antara dokumen serupa, atau antara implementasi atau versi kelas yang berbeda.
