XmlTextReader::BaseURI Property
Gets the base URI of the current node.
Assembly: System.Xml (in System.Xml.dll)

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.
#using <System.Xml.dll> using namespace System; using namespace System::IO; using namespace System::Xml; int main() { XmlTextReader^ reader = nullptr; try { //Load the reader with the XML file. reader = gcnew 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 ); } } finally { if ( reader != nullptr ) reader->Close(); } }
The example uses the file, baseuri.xml, as input.
