A [[regular expression]] ( also "RegEx" or "regex" ) is a string that is used to describe or match a set of strings, according to certain [[syntax]] rules. The specific syntax rules vary depending on the specific [[implementation]], [[programming language]], or [[Library (computing)|library]] in use. Additionally, the functionality of regex implementations can vary between [[Software versioning|version]]s.
