A real world data mining problem A machine shop has two automatic milling machines. Machines’ operation output data is in XML format. To improve the energy efficiency of the machines, operation data of power consumption and time stamps for each operation need to be extracted from the XML file. The extracted data will be calculated and then saved for analysis and comparison. Find a solution in software for this problem Save extracted data into a data file Calculate the average power consumption of each operation Display and write to an output file the elapsed time and the average power consumption of each operation
