XmlNodeReader.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.

NoteNote

In the .NET Framework 2.0, the recommended practice is to create XmlReader instances using the XmlReaderSettings class and the Create method. This allows you to take full advantage of all the new features introduced in the .NET Framework. For more information, see the Remarks section in the XmlReader reference page.

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()
  {
    XmlNodeReader reader = null;

    try
    {
       //Create and load the XML document.
       XmlDocument doc = new XmlDocument();
       doc.LoadXml("<book xmlns:bk='urn:samples'> " +
                   "<title>Pride And Prejudice</title>" +
                   "<bk:genre>novel</bk:genre>" +
                   "</book>"); 

       //Load the XmlNodeReader 
       reader = new XmlNodeReader(doc);

       //Parse the XML.  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
