Regular expression parsing can have a lot of overhead, i.e. processing power/memory usage so it's recommended that they only be used when actually needed. If you only have to search for a very specific set of text or manipulate text that is very rigidly, then there's little benefit to including regular expressions. By comparison, if you have a need to match a lot of various cases or conditions, a regular expression can be by far the more efficient or logical method to use.
