You say for example an website like Ebay. Is eBay an example or is it what you want to get data from? That question is very important since the answer is very different if you need to get data from eBay than from other sites. To get data from eBay you can use an API designed by eBay to get data from eBay and only eBay. If that is what you need then please say so. Regardless please clarify what you actually need to do. Many other sites have an API (web service?) that can make it easier. If they don't then you can scrape data from web pages.
