They occur often in programming languages like Perl and C#, in SQL in form of LIKE expressions, and in web applications. Providing support for regular expression constraints in program analysis and testing has several useful applications. We introduce a method and a tool called Rex, for symbolically expressing and analyzing regular expression constraints. Rex is implemented using the SMT solver Z3, and we provide experimental evaluation of Rex.}, publisher = {IEEE}, url = {http://approjects.co.za/?big=en-us/research/publication/rex-symbolic-regular-expression-explorer/}, edition = {ICST'10}, number = {MSR-TR-2009-137}, note = {ICST'10}, }
