Firequark was our first open source tool. It is an extension to Firebug to aid the process of HTML Screen Scraping. Firequark automatically extracts CSS selector for a single or multiple html node(s) from a web page using Firebug. The css selector generated can be given as an input to html screen scrapers like Scrapi to extract information. While working on web scraping, it's difficult to find css selector for a html node because it involves trial and error method until you find a right combination of rule (CSS selector). This is where Firequark automates this process and gets you the right CSS selector. So, in effect saving reasonable amount of developer time.
