XmlElement.Prefix Property

Gets or sets the namespace prefix of this node.

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

public override string Prefix { get; set; }

Property Value

Type: System.String
The namespace prefix of this node. If there is no prefix, this property returns String.Empty.

ExceptionCondition
ArgumentException

This node is read-only

XmlException

The specified prefix contains an invalid character.

The specified prefix is malformed.

The namespaceURI of this node is null.

The specified prefix is "xml" and the namespaceURI of this node is different from http://www.w3.org/XML/1998/namespace.

Setting this property changes the Name property, which holds the qualified name for an XmlElement. However, changing the prefix does not change the namespace URI of the element.

The following example displays information on the ISBN element.


using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book xmlns:bk='urn:samples'>" +
                "<bk:ISBN>1-861001-57-5</bk:ISBN>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    // Display information on the ISBN element.
    XmlElement elem = (XmlElement) doc.DocumentElement.FirstChild;
    Console.Write("{0}:{1} = {2}", elem.Prefix, elem.LocalName, elem.InnerText);
    Console.WriteLine("\t namespaceURI=" + elem.NamespaceURI);

  }
}
