@JanVladimirMostert It is a fair suggestion. I can also try this one too. Thanks

I think it really depends on what kinds of website you are scraping. If those websites using static type page (like php+mysql), you can use any language (like python) to download the page and parse the data. However, if those websites using javascript to dynamically load the data, you have to use some tools to simulate the javascript engine. I recently use CasperJS ( http://casperjs.org/ ) to parse a big database website, which loads data through javascript. You can find many video tutorials online like this one. https://www.youtube.com/watch?v=Kefil5tCL9o
