How to use this parser?

[anar1501]

Describe the bug
Currently, I want to perform a parser operation for a pnrgov, but I do not have any information on how to implement the parser library you wrote. Can you help me? For example, which class's method do I need to call to perform this parser operation?

What I want is, I just want to use whatever method I need to send the message in my edifact pnrgov file, and then it needs to fill the data stored in that message, let's say name, surname and whatever else, into the model class.
