[Boost-users] String processing algorithms

hi to all,i am interested in implementing some string processing algorithms{eg boyer-moore , knuth morris prat} for educational purposes. This is the first "real" exposure i will have with boost. I've done a bit of searching and i think Xpressive is the corresponding library of boost, for string processing. From what i read Xpressive is a header-only template library, so i will have to study xpressive.hpp . Any other directions i should follow? thanks in advance for your trouble, nicolas
