XmlAttribute.BaseURI XmlAttribute.BaseURI XmlAttribute.BaseURI XmlAttribute.BaseURI Property


Gets the base Uniform Resource Identifier (URI) of the node.

 virtual property System::String ^ BaseURI { System::String ^ get(); };
public override string BaseURI { get; }
member this.BaseURI : string
Public Overrides ReadOnly Property BaseURI As String

Property Value

The location from which the node was loaded or String.Empty if the node has no base URI. Attribute nodes have the same base URI as their owner element. If an attribute node does not have an owner element, BaseURI returns String.Empty.


The following example displays information on the attribute node, including its base URI.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
   //Create the XmlDocument.
   XmlDocument^ doc = gcnew XmlDocument;
   doc->Load( "http://localhost/baseuri.xml" );
   //Display information on the attribute node. The value
   //returned for BaseURI is 'http://localhost/baseuri.xml'.
   XmlAttribute^ attr = doc->DocumentElement->Attributes[ 0 ];
   Console::WriteLine( "Name of the attribute:  {0}", attr->Name );
   Console::WriteLine( "Base URI of the attribute:  {0}", attr->BaseURI );
   Console::WriteLine( "The value of the attribute:  {0}", attr->InnerText );
using System;
using System.IO;
using System.Xml;

public class Sample
  public static void Main()
    //Create the XmlDocument.
    XmlDocument doc = new XmlDocument();
    //Display information on the attribute node. The value
    //returned for BaseURI is 'http://localhost/baseuri.xml'.
    XmlAttribute attr = doc.DocumentElement.Attributes[0];
    Console.WriteLine("Name of the attribute:  {0}", attr.Name);
    Console.WriteLine("Base URI of the attribute:  {0}", attr.BaseURI);
    Console.WriteLine("The value of the attribute:  {0}", attr.InnerText);

Public Class Sample
    Public Shared Sub Main()
        'Create the XmlDocument.
        Dim doc As New XmlDocument()
        'Display information on the attribute node. The value
        'returned for BaseURI is 'http://localhost/baseuri.xml'.
        Dim attr As XmlAttribute = doc.DocumentElement.Attributes(0)
        Console.WriteLine("Name of the attribute:  {0}", attr.Name)
        Console.WriteLine("Base URI of the attribute:  {0}", attr.BaseURI)
        Console.WriteLine("The value of the attribute:  {0}", attr.InnerText)
    End Sub 'Main 
End Class 'Sample

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

A networked XML document is comprised of chunks of data aggregated using various World Wide Web Consortium (W3C) standard inclusion mechanisms and therefore contains nodes that come from different places. The BaseURI tells you where these nodes came from.

For additional information on BaseURI and how it behaves with other node types, see XmlNode.BaseURI.

This property is a Microsoft extension to the Document Object Model (DOM).
