That's misleading; matching character patterns *allows* one to make decisions based on the numerical value of part of a string. Granted, the way you showed is much more straightforward, efficient, and practical for most purposes. But regexes can select any finite subset of integers, for example, and many infinite ones as well. They are surprisingly powerful.
