I would like to help, but I'm afraid I don't really understand what it is you are asking. Is the file you posted the input or output? It would really help us if you gave a better description of your problem, as well as simple examples of what the input to your program will be, and what output you expect. Also, any Perl code you have already tried would be very helpful. Even if it doesn't work, it will still be instructive for us to see what you are trying to do. See How do I post a question effectively? for some hints on how to write an effective question.
Just to get you started, though, you might want to have a look at CPAN modules such as XML::Simple.
