Examples

The following example gets and displays the second node in the XmlNodeList.

#using <System.Xml.dll>

using namespace System;

using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<items>"
   "  <item>First item</item>"
   "  <item>Second item</item>"
   "</items>" );
   
   //Get and display the last item node.
   XmlElement^ root = doc->DocumentElement;
   XmlNodeList^ nodeList = root->GetElementsByTagName( "item" );
   Console::WriteLine( nodeList->Item( 1 )->InnerXml );
}

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

public class Sample {

  public static void Main() {

     XmlDocument doc = new XmlDocument();
     doc.LoadXml("<items>" +

                 "</items>");

     //Get and display the last item node.
     XmlElement root = doc.DocumentElement;
     XmlNodeList nodeList = root.GetElementsByTagName("item");
     Console.WriteLine(nodeList.Item(1).InnerXml);
  }
