 Your message seems to be about removing HTML tags from an HTML document.
 Unfortunately, I had trouble reading your mail because... it was full
 of HTML tags.

 You're more likely to get useful responses if you resend your mail 
 as normal (i.e., ASCII) text.

...but not _much_ more likely. We don't do people's homework for
them.

However, a hint for the first one. Write a function of type String -
[String] that tokenises then another one that determines if a set of
tokens comprises an HTML element (that's [String] - Bool). Using
this and a bit of cunning, you should get there.

Quoting Law [EMAIL PROTECTED]:
 hi, how do I define this function:
 
 tupleWithf :: [Int] - [(Int, Int)]
 
 such that 
 
 tupleWithf [x1,x2,.,xn]
 = [ (f x1, x1), (f x2 x2),, (f xn, xn) ]
   ^ you wanted a comma there, I guess.

I don't see where you're getting `f' from. I think you want the type
to be:

tupleWithf :: (Int - Int) - [Int] - [(Int, Int)]

Still, you can do this with a trivial list comprehension or map. I
leave the implementation as an exercise for the reader.
