javascript|xml| Access | data

Java's access to XML files was previously done. I later listened to one of my colleagues (the technology is very good) said: JavaScript access is more convenient and simple. So today I went home to find the data to test the next. Very convenient indeed. Welcome everyone to share! I posted the test code I was looking for. It was copied from someone else. Or changed a few mistakes ha. There will be more information on this in the future ha! Thank you for your attention! The original code please click to read the full text.
