XmlTextReader.Depth Property

Gets the depth of the current node in the XML document.

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

public override int Depth { get; }
/** @property */
public int get_Depth ()

public override function get Depth () : int

Property Value

The depth of the current node in the XML document.

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.

The following example displays each node including its depth, line number, and line position.

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

  public static void Main(){

    // Create the XML fragment to be parsed.
    string xmlFrag  = 
    @"<book> 
         <misc>
           <style>paperback</style> 
           <pages>240</pages>

    XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);

    // Create the XmlParserContext.
    XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None);

    // Create the reader.
    XmlTextReader reader = new XmlTextReader(xmlFrag, XmlNodeType.Element, context);

    // Parse the XML and display each node.
