Examples

The following example displays all the book titles.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
using namespace System::Collections;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->Load( "2books.xml" );
   
   //Get and display all the book titles.
   XmlElement^ root = doc->DocumentElement;
   XmlNodeList^ elemList = root->GetElementsByTagName( "title" );
   IEnumerator^ ienum = elemList->GetEnumerator();
   while ( ienum->MoveNext() )
   {
      XmlNode^ title = dynamic_cast<XmlNode^>(ienum->Current);
      Console::WriteLine( title->InnerText );
   }
}

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

public class Sample {

  public static void Main() {

     XmlDocument doc = new XmlDocument();
     doc.Load("2books.xml");

     //Get and display all the book titles.
     XmlElement root = doc.DocumentElement;
     XmlNodeList elemList = root.GetElementsByTagName("title");
     IEnumerator ienum = elemList.GetEnumerator();
     while (ienum.MoveNext()) {
       XmlNode title = (XmlNode) ienum.Current;
       Console.WriteLine(title.InnerText);
     }
  }
}

Imports System.IO
Imports System.Xml
Imports System.Collections

public class Sample

  public shared sub Main()

     Dim doc as XmlDocument = new XmlDocument()
     doc.Load("2books.xml")
                         
     'Get and display all the book titles.
     Dim root as XmlElement = doc.DocumentElement
     Dim elemList as XmlNodeList = root.GetElementsByTagName("title")
     Dim ienum as IEnumerator = elemList.GetEnumerator()          
     while (ienum.MoveNext())
        Dim title as XmlNode
        title = CType(ienum.Current, XmlNode)
        Console.WriteLine(title.InnerText)
     end while    
    
  end sub
end class

The example uses the file 2books.xml as input.

<!--sample XML fragment-->

    <title>Pride And Prejudice</title>

Remarks

Provides a simple "foreach" style iteration over the collection of nodes in the XmlNodeList.
