[Boost-users] REGEXP - Serializing regexp ?

Hi I'm trying to use the boost-regexp package and I'm facing an issue with this. I'm basically applying a replace algo on a list of strings using a huge list of regular expressions. It seems that the boost-regexp API allows me only to either load all regular expressions in memory (i.e creating the regexp at process start) or load one regexp at a time but re-compile it each time. Is there a way to save to disk the compiled version of the regexp (so that the regexp package would not have to re-create the statemachine) ? If not, what would be the best approach for doing this ? Thanks /jog
