In the above code I have three keys one is studentaddress,subjects and universitys. and I have arrays of values in each key. I have common values in each key like name and number in studentaddress is same in student name and number in the university values. by using similar value in the keys I need to add adress value from studentaddress key to the student tag in the university key. same like subjet names form subject key to the semister tag in the university key. I need help in the perl script to perform this operation. I am very new to perl
