XmlTextReader.Prefix Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Gets the namespace prefix associated with the current node.

Namespace:   System.Xml
Assembly:  System.Xml (in System.Xml.dll)

Public Overrides ReadOnly Property Prefix As String

Property Value

Type: System.String

The namespace prefix associated with the current node.


Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.

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

Imports System
Imports System.IO
Imports System.Xml

Public Class Sample

    Public Shared Sub Main()
        Dim reader As XmlTextReader = Nothing

            ' Load the reader with the XML file.
            reader = New XmlTextReader("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)
                        Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName)
                        Console.WriteLine(" The namespace URI is " & reader.NamespaceURI)
                    End If
                End If
            End While

            If Not (reader Is Nothing) Then
            End If
        End Try
    End Sub 'Main 
End Class 'Sample

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