XmlTextReader.Prefix Property

Gets the namespace prefix associated with the current node.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)
public override string Prefix { get; }

Property Value

Type: System.String
The namespace prefix associated with the current node.
NoteNote

In the .NET Framework version 2.0 release, the recommended practice is to create XmlReader instances using the XmlReader.Create method. This allows you to take full advantage of the new features introduced in this release. For more information, see Creating XML Readers.

The following example displays the local name of each node, and, if they exist, the prefix and namespace URI.


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


The example uses the file, book2.xml, as input.



<book xmlns:bk='urn:samples'>
  <title>Pride And Prejudice</title>
  <bk:genre>novel</bk:genre>
</book>
