You probably want String#gsub or String#gsub!. For example: $ irb --simple-prompt >> str = "<p>Welcome to ruby </p> <p> </p>" => "<p>Welcome to ruby </p> <p> </p>" >> str.gsub!(/( |\s)+/, " ") => "<p>Welcome to ruby </p> <p> </p>" >> Removing empty paragraphs is left as an exercise. For more information on String and Regexp see http://www.ruby-doc.org/docs/ProgrammingRuby/ However for anything other than the most basic transformations, you are almost certainly better off with a HTML parser like Nokogiri, than chomping HTML with regexps. -- Posted via http://www.ruby-forum.com/.

Are you saying you want to remove the '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. -- Posted via http://www.ruby-forum.com/.

It's less than optimal, as you could combine it in one go, probably, but I don't want to spend time on stuff you should be able to do on your own. -- Thank you for your brain. -MrZombie
