You have to escape the slashes and asterisk in the regex, as they are regular expression characters. http://rubular.com is a great place to learn and play around with regular expressions.
text.gsub(/\/\* start \*\/(.*)\/\* end \*\//im, replace_with)
Yes, interpolation works in regular expressions:
text.gsub(/#{start_tag}(.*)#{end_tag}/, replace_with)

How should I be escaping /* and */ ?Also, does string interpolation work in gsub regex? Say I had variables like:start_tag = "/* start */"end_tag = "/* end */"I want to do:text.gsub("#{start_tag}(.*)#{end_tag}", replace_with)
