NamespaceURI Property

XmlTextReader.NamespaceURI Property

 

Gets the namespace URI (as defined in the W3C Namespace specification) of the node on which the reader is positioned.

Namespace:   System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public override string NamespaceURI { get; }

Property Value

Type: System.String

The namespace URI of the current node; otherwise an empty string.

System_CAPS_noteNote

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.

This property is relevant to Element and Attribute nodes only.

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.
