示例

下面的示例显示有关 DocumentType 节点的信息。The following example displays information about the DocumentType node.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   
   // Create the XmlDocument.
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<!DOCTYPE book [<!ENTITY h 'hardcover'>]>"
   "<book genre='novel' ISBN='1-861001-57-5'>"
   "<title>Pride And Prejudice</title>"
   "<style>&h;</style>"
   "</book>" );
   
   // Display information on the DocumentType node.
   XmlDocumentType^ doctype = doc->DocumentType;
   Console::WriteLine( "Name of the document type:  {0}", doctype->Name );
   Console::WriteLine( "The internal subset of the document type:  {0}", doctype->InternalSubset );
}


using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {
    // Create the XmlDocument.
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<!DOCTYPE book [<!ENTITY h 'hardcover'>]>" +
                "<book genre='novel' ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "<style>&h;</style>" +
                "</book>");

    // Display information on the DocumentType node.
    XmlDocumentType doctype = doc.DocumentType;
    Console.WriteLine("Name of the document type:  {0}", doctype.Name);
    Console.WriteLine("The internal subset of the document type:  {0}", doctype.InternalSubset);
  }
}
