Examples

The following example uses the XmlAttributeCollection class (which inherits from XmlNamedNodeMap) to modify an attribute.

#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' publicationdate='1997'>   <title>Pride And Prejudice</title></book>" );
   XmlAttributeCollection^ attrColl = doc->DocumentElement->Attributes;
   
   // Change the value for the genre attribute.
   XmlAttribute^ attr = dynamic_cast<XmlAttribute^>(attrColl->GetNamedItem( "genre" ));
   attr->Value = "fiction";
   Console::WriteLine( "Display the modified XML..." );
   Console::WriteLine( doc->OuterXml );
}

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'> " & _

                "</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)
