HTML Parsing Libraries for .NET

Question

I'm looking for libraries to parse HTML to extract links, forms, tags etc.

• http://www.majestic12.co.uk/projects/html_parser.php
• http://www.netomatix.com/Products/DocumentManagement/HtmlParserNet.aspx
• http://www.developer.com/net/csharp/article.php/2230091

LGPL or any other commercial development friendly licenses are preferable.

Have you got any experience with one of this libraries? Or could you recommend another similar library?

The HTML Agility Pack has examples of exactly this type of thing, and uses xpath for familiar queries - for example (from home page), to find all links is simply:

foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a@href")) {
    //...
}
