I'm not sure what your age has to do with this submission, I know a guy who wrote a simple operating system with 15 and never put his age online just to get 'real feedback' as he put it.<p>Edit: After looking at the code it also becomes apparent that you did not write an "XML-to-JSON converter" but just put a (very simple) web-frontend in front of the crack-library.

Not to discourage you, but I don't think the title is really honest this way.
It falls over with an internal server error if you enter invalid XML. That's not good. Besides that, it's ace that you're learning and putting code out there for snarky old people like me to complain about. ;)<p>Regarding your age though, you're old too. <a href="http://www.ted.com/talks/thomas_suarez_a_12_year_old_app_developer.html" rel="nofollow">http://www.ted.com/talks/thomas_suarez_a_12_year_old_app_dev...</a> ;)
