HtmlElementCollection Class

Defines a collection of HtmlElement objects.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
public sealed class HtmlElementCollection : ICollection, 
	IEnumerable

The following code example uses HtmlElementCollection objects to print out a textual representation of the Document Object Model (DOM) of a page.

		private void PrintDomBegin()
		{
			if (webBrowser1.Document != null)
			{
				HtmlElementCollection elemColl = null;
				HtmlDocument doc = webBrowser1.Document;
				if (doc != null)
				{
					elemColl = doc.GetElementsByTagName("HTML");
					String str = PrintDom(elemColl, new System.Text.StringBuilder(), 0);
					webBrowser1.DocumentText = str;
				}
			}
		}

		private string PrintDom(HtmlElementCollection elemColl, System.Text.StringBuilder returnStr, Int32 depth)
		{
			System.Text.StringBuilder str = new System.Text.StringBuilder();

			foreach (HtmlElement elem in elemColl)
			{
				string elemName;

				elemName = elem.GetAttribute("ID");
				if (elemName == null || elemName.Length == 0)
				{
					elemName = elem.GetAttribute("name");
					if (elemName == null || elemName.Length == 0)
					{
						elemName = "<no name>";
					}
				}

				str.Append(' ', depth * 4);
				str.Append(elemName + ": " + elem.TagName + "(Level " + depth + ")");
				returnStr.AppendLine(str.ToString());

				if (elem.CanHaveChildren)
				{
					PrintDom(elem.Children, returnStr, depth + 1);
				}

				str.Remove(0, str.Length);
			}

			return(returnStr.ToString());
		}
