Sorry, I don't have my compiler (or iostream.h) at hand right now, but I
think you could derive from ..., and then write your own whitespace function
 - if it is declared as virtual in the ... class.

I don't known if this is the right approach: is a stream that filters
characters away a different class than one that doesn't? Are there any
other way? (you could use the filebuf members directly, writing your own
extraction functions, or make a new filebuf, or ..., but that isn't the
right way)

Try it out.

I am a newbie to C/C++ and I hope that I addressed my following
problems properly.
