Usage

Common usage:

from ijson import parse

f = urlopen('http://.../') # some huge JSON
parser = parse(f)
while True:
    prefix, event, value = parser.next()
    if prefix == 'earth.europe' and event == 'start_array':
        while prefix.startswith('earth.europe'):
            prefix, event, value = parser.next()
            if event == 'map_key':
                key = value
                prefix, event, value = parser.next()
                do_something_with(key, value)

Acknowledgements

Ijson was inspired by yajl-py wrapper by Hatem Nassrat. Though ijson borrows almost nothing from the actual yajl-py code it was used as an example of integration with yajl using ctypes.
