Your requirement is unclear. Are you saying you want to remove the 
&nbsp;'s within the fourth paragraph only, and remove the fifth 
paragraph entirely?

I've shown you how to use gsub, and where to find more documentation on 
it. String#scan might be useful too.

I suggest you use them in whatever way you need, since only you 
understand what you're trying to achieve.
