Every regular expression can be written solely in terms of the Kleene star and set unions over finite words. This is a surprisingly difficult problem. As simple as the regular expressions are, there is no method to systematically rewrite them to some normal form. The lack of axiom in the past led to the star height problem.
To decide whether two given regular expressions describe the same language, each can be converted into an equivalent minimal deterministic finite automaton via Thompson's construction, powerset construction, and DFA minimization. If, and only if, the resulting automata agree up to renaming of states, the regular expressions' languages agree.
Any amount of text can be matched by a regular expression. Languages that use this type of regular expression include Perl, Java, JavaScript, Python, Ruby, .NET, and XML. A list of the regular expressions accepted by this search and replace box has been compiled for reference by the Mozilla Contributors.
