ijson 0.2.0

A Python wrapper to YAJL providing standard iterator interface to streaming JSON parsing

Ijson is a Python wrapper to YAJL which is a streaming SAX-like JSON parser. Ijson provides a standard Python iterator interface for it.

Usage

Basic usage:

from ijson import parse

f = urlopen('http://.../') # some huge JSON
parser = parse(f)
while True:
    event, value = parser.next()
    if event == 'start_map':
        while event != 'end_map':
            event, value = parser.next()
            if event == 'map_key' and value == 'title':
                event, value = parser.next()
                do_something_with(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.
