Your Task is to download an HTML document and parse it.
There are 21 pages that we are parsing. Good news is that all 21 pages use the same template.
Once we get the data we want, we will
1. Compare it to the previous entry in the database. If they are the same, we will call a website PHP script.
2. We store it in the local computer database. All entries need to be time and date stamped.
I heard the nokogiri gem install is the way to go for DOM parsing. I am open to other solutions but they must produce excellent results.
