http://www.regular-expressions.info/ was a lot of help for me.

Flexibility is open for datate, as long as the requirements don't change,
only the "input", regexes do the job. Rewriting a regex when the
requirements change is often a terrible job. Certainly with the bigger ones,
commenting or documenting what it is exactly what they do, and/or using a
regex explainer tool is needed to do it in a limited amount of time without
rewriting the whole damn thing.

Indeed.
