Parsing JSON with Python

I'm getting an error while parsing a JSON response in Python. Ex:

{
    "oneliners": [
        "she\开发者_如何转开发's the one",
        "who opened the gates"
    ]
}

The JSON decoder coughs up on the invalid escape on the single quote. Typically do people apply a REGEX to remove the escape slash character prior to decoding a response that can potentially contain an invalid escape?

Pyparsing ships with a JSON parsing example (or you can get it online here):

>>> text = r"""{
...     "oneliners": [
...         "she\'s the one",
...         "who opened the gates"
...     ]
... } """
>>> text
'{       \n    "oneliners": [       \n        "she\\\'s the one",       \n        "who opened the gates"       \n    ]       \n} '
>>> obj = jsonObject.parseString(text)
>>> obj.asList()
[['oneliners', ["she\\'s the one", 'who opened the gates']]]
>>> obj.asDict()
{'oneliners': (["she\\'s the one", 'who opened the gates'], {})}
>>> obj.oneliners
(["she\\'s the one", 'who opened the gates'], {})
>>> obj.oneliners.asList()
["she\\'s the one", 'who opened the gates']

Don't be put off by the seeming inclusion of a dict (the '{}') in obj.oneliners, that is just the repr output for a pyparsing ParseResults object. You can just treat obj.oneliners like an ordinary list - or if you like, extract its contents as a list using asList as shown.

if you have \' character sequence in your JSON string representation, and you KNOW it should be ', it means it was improperly escaped before, you should fix the problem there.

if you can't, you should do the replacement before you provide such a string to the JSON parser. simplejson will fail parsing it, cjson or anyjson would not fail, but will handle it literally, so you will have the backslash-apostrophe sequence in the resulting data.

---

import json
s = """{
 "oneliners": [
 "she\'s the one",
 "who opened the gates"
 ]
}"""

print "%r" % json.loads(s)

This appears to work just fine, in Python 2.6 and upwards anyway.
