Ruby Webpage Parser

How to parse a Website with a Ruby script; all the time I am searching over Internet documents (and some funny contents, like manga... yeah I love manga). So, I decided to develop a Ruby script webpage parser; in the video I am showing the webpage parsing process in a Manga Cataloge website, so after refine the script we can use it to know if a content was changed (and after download its content... the new obviously).

Do you have a project idea? Let's make it together!
