Web scraping is an approach for extracting data from websites that don’t have an API. Web scraping code is inherently “brittle” (prone to breaking over time due to changes in the website content and structure), but it’s a flexible technique with a broad range of uses.
This tutorial will show you how to scrape websites with Ruby and the Watir gem. Watir is powered by Selenium, which means that unlike Mechanize you can use it to interact with JavaScript.
