Retrieves the node at the specified index in the XmlNamedNodeMap.

public:
 virtual System::Xml::XmlNode ^ Item(int index);

public virtual System.Xml.XmlNode Item(int index);

public virtual System.Xml.XmlNode? Item(int index);

abstract member Item : int -> System.Xml.XmlNode
override this.Item : int -> System.Xml.XmlNode

Public Overridable Function Item (index As Integer) As XmlNode

Parameters

index: Int32

The index position of the node to retrieve from the XmlNamedNodeMap. The index is zero-based; therefore, the index of the first node is 0 and the index of the last node is Count -1.

Returns

XmlNode

The XmlNode at the specified index. If index is less than 0 or greater than or equal to the Count property, null is returned.

Examples

The following example uses the XmlAttributeCollection class (which inherits from XmlNamedNodeMap) to display all the attributes of a book.

#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;
   Console::WriteLine( "Display all the attributes for this book..." );
   for ( int i = 0; i < attrColl->Count; i++ )
   {
      Console::WriteLine( "{0} = {1}", attrColl->Item( i )->Name, attrColl->Item( i )->Value );

   }
}

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;

     Console.WriteLine("Display all the attributes for this book...");
     for (int i=0; i < attrColl.Count; i++)
     {
        Console.WriteLine("{0} = {1}", attrColl.Item(i).Name, attrColl.Item(i).Value);
     }
  }
}

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

    Console.WriteLine("Display all the attributes for this book...")
    Dim i As Integer
    For i = 0 To attrColl.Count - 1
       Console.WriteLine("{0} = {1}", attrColl.Item(i).Name,attrColl.Item(i).Value)
    Next
    
  end sub
end class
