With scrappy, what you really get is like a full fledged Vabba crawling framework or like a web scraping framework. So it really makes it easy for you to extract data from any website. There are other libraries like beautiful soup or Aleximal or in Java, we have J soup that are only focused around parsing HTML and getting or getting data from HTML and XML files. It lets you automate the discovery and the linking of all this different data that was never intended to be put together.
