Examples
The following example displays the local name of each node, and, if they exist, the prefix and namespace URI.
#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( "book2.xml" );
// Parse the file. If they exist, display the prefix and
// namespace URI of each node.
while ( reader->Read() )
{
if ( reader->IsStartElement() )
{
if ( reader->Prefix == String::Empty )
Console::WriteLine( "<{0}>", reader->LocalName );
else
{
Console::Write( "<{0}:{1}>", reader->Prefix, reader->LocalName );
Console::WriteLine( " The namespace URI is {0}", reader->NamespaceURI );
}
}
}
}
finally
{
if ( reader != nullptr )
reader->Close();
}
}
using System;
using System.IO;
using System.Xml;
public class Sample {
public static void Main() {
XmlTextReader reader = null;
try {
// 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()) {
if (reader.Prefix==String.Empty)
{
Console.WriteLine("<{0}>", reader.LocalName);
}
else {
Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName);
Console.WriteLine(" The namespace URI is " + reader.NamespaceURI);
}
}
}
}
finally {
if (reader != null)
reader.Close();
}
}
} // End class
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("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)
Else
Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName)
Console.WriteLine(" The namespace URI is " & reader.NamespaceURI)
End If
End If
End While
Finally
If Not (reader Is Nothing) Then
reader.Close()
End If
End Try
End Sub
End Class
The example uses the file, book2.xml
, as input.
<book xmlns:bk='urn:samples'>
<title>Pride And Prejudice</title>
<bk:genre>novel</bk:genre>

Remarks
Note
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.
