In-Depth Information
This recipe will create a bot that will scan sites that contain information about a famous
person that you will choose. The bot will attempt to obtain the person's birth year. The bot
works by calling on Google to find web sites that contain the person's name. The bot then
scans the HTML of each of these pages looking for the person's birth year.
This recipe is shown in Listing 11.6.
