Regex Module Example

The Internet Movie Database (imdb.com) provides a daily feed of movie stars birthdays (http://rss.imdb.com/daily/born/). The feed seems to be in somewhat random order. Using regular expressions we can extract the birth year for each celebrity from the description and add it as its own field: birth_year. Then we can re-order order the feed from youngest to oldest.
