[Haskell-beginners] Getting Stuff out of IO Handles

[Raphael Päbst]

Hey everyone!
This is probably a stupid question, but is there a way to get stuff
out of a IO handle?
If I do something with an IO handle, reading in data from a file for
example and then do something with the data, is there a way to get the
results out of the handle, comparable to the return in a do block?
Or do all operations on the data have to happen inside the handle?
Thanks

Raf
