convert xml file to wbxml with c program

Question

I have to write a C program to convert XML file to WBXML format, without using external conversion library. Is it possible?

I have created the XML file in C and now want to convert it into WBXML file.

Answer 1

You want to know if it is possible? - Yes.

You want to know how? - check the implementation of one of the external libraries. I'm sure you can get an idea if you browse the source code.
