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
