So, write a regexp which matches any number of &nbsp; or space, followed 
by </p>, followed by end of string. I've given you the tools to do that 
already.

If you can't make it work then show what you tried, and we can explain 
what needs changing.

You can test your regexps using irb, or you can use this web site:
