From: Wells on 9 Dec 2009 17:51 Is there some way to finagle the json module to parse JSON (well, almost JSON) where the object keys are not in quotes? I know it's not 100% valid JSON, but I'm just curious. I don't have control over the data, so I can't make it fit the spec :)

The JSON library that ships with Python doesn't appear to be built for malformed JSON like what you mention, and making it handle it will take a bit of work on your part, but here's a start (based on my 2.6.4 installation): In /path_to_python_standard_library/json/decoder.py (please back this up before making any changes), comment out the try/except block that tries to load scanstring from _json and duplicate the last line (c_scanstring = None), removing its indentation. You'll then need to modify py_scanstring() to meet your needs, but be sure you understand what it's doing first. You'll need to track whether you found the leading '"' for the key and look for the other one if you did, but just look for the ':' otherwise. Again, this isn't an advisable solution, and it won't work in all cases even if you have the best of luck, but it may just work in enough cases. It's pretty amazing that the incoming document doesn't match the spec, though. The only correct solution would be to fix the library that generated it. |
