Question

Do any jQuery-like html element selector libraries exist in the Dot Net world? I am building an application which involves huge amount of html parsing.

Say I want to enumerate all ‘href’s and ‘src’s inside only a selected ‘div’s having its id like “post_message_%”.
Or say want to select the name and value strings within a form with a specific id or input type(eg. hidden or radio)

I can write the code..but first looking for any existing solution, so that I can use it and save my time for something else.

You should check out the Html Agility pack, available here.
Here’s a use case from their website, that uses XPATH selectors:

HtmlDocument doc = new HtmlDocument();
doc.Load("file.htm");
foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a[@href"])
{
   HtmlAttribute att = link["href"];
   att.Value = FixLink(att);
}
doc.Save("file.htm");
