Here we come to one new milestone: the JavaScript-driven or JS-rendered websites scrape.
Recently a friend of mine got stumped as he was trying to get content of a website using PHP simplehtmldom library. He was failing to do it and finally found out the site was being saturated with JavaScript code. The anti-scrape JavaScript insertions do a tricky check to see if the page is requested and processed by a real browser and only if that is true, will it render the rest of page’s HTML code.
