Since you mentioned Selenium and web client, I'll just go on and assume you were not talking about screen scraping (note that there is only one p in that word). Selenium is a tool that will do that, but obviously one with a user interface. Since you have not stated your ultimate goal, I can't really tell if you really need Selenium. Web/Page scraping can be done quite easily per code with the Html Agility Pack
]. This is a free and great implementation which I have used myself before and there are also quite a few of our members who are using it.
