Solving Real Problems

Knowing how to wield regular expressions unleashes processing powers you might not even know were available. Numerous times in any given day, regular expressions help me solve problems both large and small (and quite often, ones that are small but would be large if not for regular expressions).

Showing an example that provides the key to solving a large and important problem illustrates the benefit of regular expressions clearly, but perhaps not so obvious is the way regular expressions can be used throughout the day to solve rather “uninteresting” problems. I use “uninteresting” in the sense that such problems are not often the subject of bar-room war stories, but quite interesting in that until they’re solved, you can’t get on with your real work.
