Thank you so must for your effort. This is much more succinct than
what I came up with!

File.open("app/views/layouts/management.rhtml", "r") do |infile|
          file_text=""
           while (line = infile.gets)
                file_text << line
           end

           script_block=file_text.match("<!--scripts-->[\\S\\s]*?<!--
endscripts-->")


           script_block=script_block.to_s
           script_refs=script_block.scan(/[^\"]+.js/)

           script_refs.length

           script_refs.each do |ref|
               base_path = "public/"
               puts "#{base_path}#{ref}"
           end
       end
