Just for the sake of TIMTOWTDI, here is an alternative approach that you could take to this task.
Which prints..
The advantage of an approach such as this is that you do away with your if/else conditionals, so it becomes more scalable. For example, if you suddenly had to extract 100 sets of data instead of three, you wouldn't need to alter the code at all. But using your original approach, you'd need to add a separate conditional statement for each of the 100 possibilities. Explaining the pattern match in that code...
The anchors (^ and $) are probably not completely necessary in this case, however it's a good habit to anchor your pattern matches where ever possible, as it speeds things up. Hope this helps,
