XmlNodeReader.get_Depth Method

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

Remarks

The Depth property indicates how many levels of parent nodes the current node has. The root element is at depth 0. Attributes are not counted.

This property is useful for tracking the current position within the XML hierarchy while iterating through the document.

Example

using System;
using System.Xml;

public class Example
{
    public static void Main(string[] args)
    {
        XmlDocument doc = new XmlDocument();
        doc.LoadXml("<root><element attr='value'>text</element></root>");

        XmlNodeReader reader = new XmlNodeReader(doc);

        while (reader.Read())
        {
            Console.WriteLine($"Node Type: {reader.NodeType}, Depth: {reader.Depth}");

            if (reader.NodeType == XmlNodeType.Element)
            {
                Console.WriteLine($"  Name: {reader.Name}");
                // Reading attributes will not increase the depth.
                while (reader.MoveToNextAttribute())
                {
                    Console.WriteLine($"  Attribute: {reader.Name} = {reader.Value}, Depth: {reader.Depth}");
                }
                // Move back to the element node.
                reader.MoveToElement();
            }
        }
        reader.Close();
    }
}
            

Output

Node Type: Element, Depth: 0
  Name: root
Node Type: Element, Depth: 1
  Name: element
  Attribute: attr = value, Depth: 1
Node Type: Text, Depth: 2
Node Type: EndElement, Depth: 1
Node Type: EndElement, Depth: 0
