The code looks like this, and the importance of the codebase is found in this example, and if you build your own code base, you can get it out of your own code base, so you can take whatever you need to get out of it at any time. The codebase is guaranteed to be normative and correct, and has simple module annotations.

This is today on the Internet to find the XML to JSON format code, others packaged quickly, saving me a lot of time ah.
