NodeType Property

XmlTextReader.NodeType Property

Gets the type of the current node.

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

public override XmlNodeType NodeType { get; }
/** @property */
public XmlNodeType get_NodeType ()

public override function get NodeType () : XmlNodeType

Not applicable.

Property Value

One of the XmlNodeType values representing the type of the current node.

NoteNote:

In the Microsoft .NET Framework version 2.0 release, the recommended practice is to create XmlReader instances using the System.Xml.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.

This property never returns the following XmlNodeType types: Document, DocumentFragment, Entity, EndEntity, or Notation.

The following example reads an XML file and displays each of the nodes.

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

public class Sample {

  private const String filename = "items.xml";

  public static void Main() {
  
     XmlTextReader reader = null;

        // Load the reader with the data file and ignore all white space nodes.         
        reader = new XmlTextReader(filename);
        reader.WhitespaceHandling = WhitespaceHandling.None;

        // Parse the file and display each of the nodes.
        while (reader.Read()) {
           switch (reader.NodeType) {
             case XmlNodeType.Element:
