A new XmlSignificantWhitespace node.

This method is a Microsoft extension to the Document Object Model (DOM). It is used when you want to manually format your document.

Although this method creates the new object in the context of the document, it does not automatically add the new object to the document tree. To add the new object, you must explicitly call one of the node insert methods.

The following example adds significant white space to the document.

using System;
using System.Xml;

public class Sample {

  public static void Main() {

      XmlDocument doc = new XmlDocument();
      doc.LoadXml("<author xml:space='preserve'>" +
                  "<last-name>Corets</last-name>" + 

      Console.WriteLine("InnerText before...");

      // Add white space.     
      XmlNode currNode = doc.DocumentElement;
      XmlSignificantWhitespace sigws = doc.CreateSignificantWhitespace("\t");
      currNode.InsertAfter(sigws, currNode.FirstChild);

      Console.WriteLine("InnerText after...");
