XmlReader.NamespaceURI Property

When overridden in a derived class, 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 abstract string NamespaceURI { get; }
/** @property */
public abstract String get_NamespaceURI ()

public abstract function get NamespaceURI () : String

Property Value

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

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.

XmlReader reader = XmlReader.Create("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);
    }
  }
}       
reader.Close();

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>
