struct to json/yaml/xml/whatever codegen

[Daniel N via Digitalmars-d-learn]

Is anyone aware of a tool which does something akin to the 
following:

Given a C-like definition, automatically generate pure C code 
with no dependencies.

Input c-struct:
  struct Person
  {
    int   id;
    char* name;
  }     

Output minimal c-code:
  void dumpPerson(Person* p)
  {
  	printf("<Person><id>%d</id><name>%s</name></Person>", p->id, 
p->name);	
  }

It's easy to write in D... just want to avoid reinventing the 
wheel.
