Answer 1

Use htmlagilitypack

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml("yourHtml");

foreach(var item in doc.DocumentNode.SelectNodes("//div"))// "//div" is a xpath which means select div nodes that are anywhere in the html
{
 item.InnerHtml;//your div content
}

If you want only B tags..

foreach(var item in doc.DocumentNode.SelectNodes("//B"))
    {
     item.OuterHtml;//your B tag and its content
    }
