Gets an enumerator that iterates through the child nodes in the current node.

public:
 System::Collections::IEnumerator ^ GetEnumerator();

public System.Collections.IEnumerator GetEnumerator();

member this.GetEnumerator : unit -> System.Collections.IEnumerator

Public Function GetEnumerator () As IEnumerator

Returns

IEnumerator

An IEnumerator object that can be used to iterate through the child nodes in the current node.

Examples

The following example displays all the books in the XML document.

#using <System.Xml.dll>

using namespace System;
using namespace System::Collections;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->Load( "books.xml" );
   Console::WriteLine( "Display all the books..." );
   XmlNode^ root = doc->DocumentElement;
   IEnumerator^ ienum = root->GetEnumerator();
   XmlNode^ book;
   while ( ienum->MoveNext() )
   {
      book = dynamic_cast<XmlNode^>(ienum->Current);
      Console::WriteLine( book->OuterXml );
      Console::WriteLine();
   }
}

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

public class Sample {

  public static void Main() {

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

    Console.WriteLine("Display all the books...");
    XmlNode root = doc.DocumentElement;
    IEnumerator ienum = root.GetEnumerator();
    XmlNode book;
    while (ienum.MoveNext())
    {
      book = (XmlNode) ienum.Current;
      Console.WriteLine(book.OuterXml);
      Console.WriteLine();
    }
  }
}

Imports System.Collections
Imports System.Xml

public class Sample

  public shared sub Main()
  
    Dim doc as XmlDocument = new XmlDocument()
    doc.Load("books.xml")

    Console.WriteLine("Display all the books...")
    Dim root as XmlNode = doc.DocumentElement
    Dim ienum as IEnumerator = root.GetEnumerator()
    Dim book as XmlNode
    while (ienum.MoveNext())      
      book = CType(ienum.Current, XmlNode)
      Console.WriteLine(book.OuterXml)
      Console.WriteLine()
    end while

  end sub
end class

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