Depth Property

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 Value

Type: System.Int32
The depth of the current node in the XML document.

NoteNote:

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

           <style>paperback</style> 
           <pages>240</pages>
         </misc> 
        </book>";

    XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);

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

    // Create the reader.
