When I do web scraping before, I used R and the prestigious “rvest” package to scrape links and text from webpages like this Congress “SELF DRIVE Act” page. (put the “SELF DRIVE Act” page here: https://www.congress.gov/congressional-record/2017/9/6/house-section/article/H6667-1). The problem this time is that the Fortune 500 2018 webpage is a bit different, which is a scrolling webpage just like twitter, meaning when you scroll down to the bottom of the page, the webpage will extend and show more information there, even though the url remains the same. Hence, when you use the conventional way of web scraping by using “rvest” alone, it will only give you the first twenty companies, the ones you can see without scrolling, instead of the entire 500 companies. And this R script shows how I web scraping Scrolling Website
This R script shows how I web scraping scrolling website, a kind of website just like twitter and the Fortune 500 2018 list (http://fortune.com/fortune500/list/), when you scroll down the webpage, the webpage will extend and show more information there, even though the url remains the same. Hence, when you use the conventional way of web scraping by using “rvest” alone, it will only give you the first twenty companies, the ones you can see without scrolling. Here’s how I address this issue.
