若未找到匹配節點，則為指定名稱XmlNode的 Anull。

範例

以下範例使用 XmlAttributeCollection 類別（繼承自 XmlNamedNodeMap）來修改屬性。

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

public class Sample
{
  public static void Main()
  {
     XmlDocument doc = new XmlDocument();
     doc.LoadXml("<book genre='novel' publicationdate='1997'> " +
                 "  <title>Pride And Prejudice</title>" +
                 "</book>");

     XmlAttributeCollection attrColl = doc.DocumentElement.Attributes;

     // Change the value for the genre attribute.
     XmlAttribute attr = (XmlAttribute)attrColl.GetNamedItem("genre");
     attr.Value = "fiction";

     Console.WriteLine("Display the modified XML...");
     Console.WriteLine(doc.OuterXml);
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book genre='novel' publicationdate='1997'> " & _
                "  <title>Pride And Prejudice</title>" & _
                "</book>")
                         
    Dim attrColl as XmlAttributeCollection = doc.DocumentElement.Attributes

    ' Change the value for the genre attribute.
    Dim attr as XmlAttribute = CType(attrColl.GetNamedItem("genre"),XmlAttribute)
    attr.Value = "fiction"

    Console.WriteLine("Display the modified XML...")
    Console.WriteLine(doc.OuterXml)
    
  end sub
end class

XmlNode若找不到匹配的節點，則使用匹配的本地名稱與命名空間 URInull。
