Public Overrides ReadOnly Property BaseURI As String

Property Value

Type: System.String

The base URI of the current node.

System_CAPS_noteNote

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.

A networked XML document is comprised of chunks of data aggregated using various W3C standard inclusion mechanisms and therefore contains nodes that come from different places. DTD entities are an example of this, but this is not limited to DTDs. The base URI tells you where these nodes came from. If there is no base URI for the nodes being returned (for example, they were parsed from an in-memory string), String.Empty is returned.

The following example displays the base URI for each of the nodes.

Option Explicit
Option Strict

Imports System
Imports System.IO
Imports System.Xml

Public Class Sample

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

      Try
         'Load the reader with the XML file.
         reader = New XmlTextReader("http://localhost/baseuri.xml")

         'Parse the file and display the base URI for each node.
         While reader.Read()
            Console.WriteLine("({0}) {1}", reader.NodeType, reader.BaseURI)
         End While

      Finally
         If Not (reader Is Nothing) Then
            reader.Close()
         End If
      End Try
   End Sub 'Main ' End class
End Class 'Sample 

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