The following example displays the local name of each node, and, if they exist, the prefix and namespace URI.

Visual Basic

Dim reader As XmlReader = XmlReader.Create("book2.xml")

' Parse the file.  If they exist, display the prefix and 
' namespace URI of each node.
While reader.Read()
  If reader.IsStartElement() Then
    If reader.Prefix = String.Empty Then
      Console.WriteLine("<{0}>", reader.LocalName)
    Else
      Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName)
      Console.WriteLine(" The namespace URI is " + reader.NamespaceURI)
    End If
  End If
End While
reader.Close()

XmlReader reader = XmlReader.Create("book2.xml");

// Parse the file.  If they exist, display the prefix and 
// namespace URI of each node.
while (reader.Read()) {
  if (reader.IsStartElement()) {
    if (reader.Prefix==String.Empty)
      Console.WriteLine("<{0}>", reader.LocalName);
    else {
      Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName);
      Console.WriteLine(" The namespace URI is " + reader.NamespaceURI);
    }
  }
}       
reader.Close();

The example uses the file, book2.xml, as input.
