XmlAttribute.BaseURI Property

Gets the base URI of the node.

[Visual Basic]
Overrides Public ReadOnly Property BaseURI As String
[C#]
public override string BaseURI {get;}
[C++]
public: __property String* get_BaseURI();
[JScript]
public override function get BaseURI() : 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.

Remarks

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. 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).

Example

[Visual Basic, C#, C++] The following example displays information on the attribute node, including its base URI .

    Console.WriteLine("Base URI of the attribute:  {0}", attr.BaseURI);
    Console.WriteLine("The value of the attribute:  {0}", attr.InnerText);

  }

    //Display information on the attribute node. The value
    //returned for BaseURI is 'http://localhost/baseuri.xml'.
    XmlAttribute* attr = doc->DocumentElement->Attributes->ItemOf[0];
    Console::WriteLine(S"Name of the attribute:  {0}",attr->Name);
    Console::WriteLine(S"Base URI of the attribute:  {0}",attr->BaseURI);
    Console::WriteLine(S"The value of the attribute:  {0}",attr->InnerText);

}

[Visual Basic, C#, C++] The sample uses the file, baseuri.xml, as input.
