a website that will compare prices of a yamaha baby grand piano
<p>i would like to design a website that will crawl 100 other websites and post the current prices in ascending order of the same model yamaha baby grand piano. the prices on these sites will appear in simple HTML. the question is will i have to modify my algorithm for every single site, or is there some kind of artificially intelligent tool that can find the product on the given site and give my its price?</p>
