[Haskell] Evaluating expressions given as String

Hello everybody. I'm working on a haskell project in which I need to evaluate haskell expressions that are given in an input File. For instance: A file containing "Peter==Peter" or "3+2==5" or "home in [a-z]*sex[a-z]*" (see I need to use regular expressions too) is given as input The file contents are read as String type and I need to evaluate them to True or False. I'm looking for the way to parse and translate these expressions in order to evaluate them. Thanks for you help.
