So far I did not see any attempt to create a XML Parser on a microcontroller. Perhaps
the current techniques require too much memory. I am not sure on that last statement b'cos
I did not write a XML parser before. The current yacc is within the range of 60000 bytes
in my Linux box.

I guess the best example is Tiny C compiler. It is very small and the parser is hard coded.
Okay the parser is big but it gives you an insight of how much work you have to do.

Minus object generation it would still be pretty large for you PIC memory capacity. External
memory may be required.
