Answer 1

I like to use the Html Agility Pack is very easy to use, although recently there are not many updates in it, it can still be used. For example, capturing all links

HtmlWeb client = new HtmlWeb();
HtmlDocument doc = client.Load("http://yoururl.com");            
HtmlNodeCollection Nodes = doc.DocumentNode.SelectNodes("//a[@href]");         

foreach (var link in Nodes)
{                
    Console.WriteLine(link.Attributes["href"].Value);
}

Search strings, you need to search for regular expressions. As for labeling, after you have a substring position, it should be simple enough to use this to add something to wrap a phrase.
