Well, that's almost certainly not what the OP wants!

irb> str = "<p>Welcome to ruby &nbsp;&nbsp;</p> <p>&nbsp;&nbsp;</p>"
=> "<p>Welcome to ruby &nbsp;&nbsp;</p> <p>&nbsp;&nbsp;</p>"
irb> str.delete('&nbsp;')
=> "<>Welcome to ruy </> <></>"

Look at the documentation for String#delete

Then take a look at String#gsub

I suspect that you want to do two passes: one for '&nbsp;' and one for  
empty paragraphs.
