Class Method Details

Patches inside Nokogiri to count, time, and print searches. At end of baking you can puts Nokogiri::XML::PROFILE_DATA to see the totals. The counts hash is defined outside of the if block so that code that prints it doesn't explode if run without the env var. The print_profile_data method is also provided for a nice printout
