 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

屬性值

XmlNamedNodeMap

包含 XmlEntity 節點的 XmlNamedNodeMap。 傳回的 XmlNamedNodeMap 是唯讀的。

範例

下列範例會顯示 XML 檔中宣告之實體的相關資訊。

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

此範例會使用 檔案 doment.xml 作為輸入。

<!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">
