範例

下列範例會從根項目移除所有屬性。The following example removes all attributes from the root element.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book genre='novel' ISBN='1-861001-57-5'><title>Pride And Prejudice</title></book>" );
   XmlElement^ root = doc->DocumentElement;
   
   // Remove all attributes from the root element.
   if ( root->HasAttributes )
      root->RemoveAllAttributes();

   Console::WriteLine( "Display the modified XML..." );
   Console::WriteLine( doc->InnerXml );
}

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

public class Sample
{
  public static void Main()
  {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    XmlElement root = doc.DocumentElement;

    // Remove all attributes from the root element.
    if (root.HasAttributes)
      root.RemoveAllAttributes();
    
    Console.WriteLine("Display the modified XML...");
    Console.WriteLine(doc.InnerXml);

  }
}
Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" & _
                "<title>Pride And Prejudice</title>" & _
                "</book>")      

    Dim root as XmlElement = doc.DocumentElement

    ' Remove all attributes.
    if (root.HasAttributes)
      root.RemoveAllAttributes()
    end if

    Console.WriteLine("Display the modified XML...")
    Console.WriteLine(doc.InnerXml)

  end sub
end class
