C# How to delete XML/HTML comments with regular expression

Question

The fragment below doesn\'t work for me.

fragment = Regex.Replace(fragment, \"\", String.Empty , RegexOptions.Multiline  );

Please don't use regular expressions to work with markup languages - you need to use a better tool that is built for that kind of job.

Use the Html Agiliy Pack instead. I even found this article in which a reader (named Simon Mourier) comments with a function that uses the Html Agility Pack to remove comments from a document:

  RemoveComments(doc.DocumentNode); 
  doc.Save(Console.Out); // show after 
} 

static void RemoveComments(HtmlNode node)
{
    if (!node.HasChildNodes)
    {
        return;
    }
