Following LINKS Automatically with Scrapy CrawlSpider

Scrapy gives us access to two main spiders classes, the generic spider which we have used lots of time before in other videos plus this CrawlSpider that works in a slightly different way. We can give it a rule set and get it to follow links automatically, passing the ones that we want matched back to our parse function with a callback. This makes incredibly easy full website data scraping. In this video I will explain to you how to use the CrawlSpider, what the Rule and LinkExtrator do and how to use them, and also demo how it works.
