Subject: Re: how to use gsub method?

This is your code :
require 'net/http'


page= Net::HTTP.new('www.google.co.kr',80)


reg = page.get('/index.html')

reg.gsub(/a/) {|gg| puts gg}
puts reg


Your are trying to use gsub on the object returned by Net::HTTP , which 
isn't a string . Your code should look like this :

require 'net/http'


page= Net::HTTP.new('www.google.co.kr',80)


reg = page.get('/index.html')

reg.body.gsub!(/a/) {|gg| puts gg}
puts reg.body

Pay attention to the gsub! , which modifies the string in-place .Judging 
by your script,that is what you want .
