Web page content extraction

Recently I have created a personal project focus on fetching and parsing data from web pages.

The project is open source and can be accessed at https://github.com/nguyenducgiang/extract-web-page

I have introduce about this at Ruby Hanoi meetup 2. The slide can be viewed here https://docs.google.com/presentation/d/1ZMf1Nx8awP7Txq0tbxB6UHo1UtFD7J9XXAA6rQg4uyc/edit?usp=sharing
