範例

下列範例會顯示 ISBN 元素的資訊。The following example displays information on the ISBN 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 xmlns:bk='urn:samples'>"
   "<bk:ISBN>1-861001-57-5</bk:ISBN>"
   "<title>Pride And Prejudice</title>"
   "</book>" );
   
   // Display information on the ISBN element.
   XmlElement^ elem = dynamic_cast<XmlElement^>(doc->DocumentElement->FirstChild);
   Console::Write( "{0}:{1} = {2}", elem->Prefix, elem->LocalName, elem->InnerText );
   Console::WriteLine( "\t namespaceURI={0}", elem->NamespaceURI );
}

// This code produces the following output.
// bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples
using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book xmlns:bk='urn:samples'>" +
                "<bk:ISBN>1-861001-57-5</bk:ISBN>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    // Display information on the ISBN element.
    XmlElement elem = (XmlElement) doc.DocumentElement.FirstChild;
    Console.Write("{0}:{1} = {2}", elem.Prefix, elem.LocalName, elem.InnerText);
    Console.WriteLine("\t namespaceURI=" + elem.NamespaceURI);
  }
}

// This code produces the following output.
// bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples
Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

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

    ' Display information on the ISBN element.
    Dim elem as XmlElement 
    elem = CType(doc.DocumentElement.ChildNodes.Item(0),XmlElement) 
    Console.Write("{0}:{1} = {2}", elem.Prefix, elem.LocalName, elem.InnerText)
    Console.WriteLine("  namespaceURI=" + elem.NamespaceURI)
  end sub
end class

' This code produces the following output.
' bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples

備註

這是在建立時指定的命名空間 URI。This is the namespace URI specified at creation time. 例如, NamespaceURI是 urn: 元素<的範例 bk: book xmlns: bk = "urn: samples" >For example, NamespaceURI is urn:samples for the element <bk:book xmlns:bk= "urn:samples">
