[Haskell-cafe] how to apply a function which returns IO() to a list?

Hi, I have this function which write a file: writeHtml b x y = do writeFile (b ++ ".html") (htmlCode b x y) i need to apply to each member of a given list: the way i always try to codify functions in haskell is allways the same, the most primitive one and i think i cant use it here. writeList [] = ??? writeList (x:xs) = (writeHtml x) ??? How should i do this? Many thx, Nuno SAntos
