        I'm not sure of a great way to match cnn.com with this... but it works for the other urls in the text string.

body_html = "I hate cnn.com and www.cnn.com even http://cnn.com and OMFG especially http://www.cnn.com and https://cnn.com"
regex = Regexp.new '((https?:\/\/|www\.)([-\w\.]+)+(:\d+)?(\/([\w\/_\.]*(\?\S+)?)?)?)'
body_html.gsub!( regex, '<a href="\1">\1</a>' )
