如何从 JSON 文件中的每个值中删除空格和换行符？

我有一个JSON文件具有以下结构：

{
    "name":[
        {
            "someKey": "\n\n   some Value   "
        },
        {
            "someKey": "another value    "
        }
    ],
    "anotherName":[
        {
            "anArray": [
                {
                    "key": "    value\n\n",
                    "anotherKey": "  value"
                },
                {
                    "key": "    value\n",
                    "anotherKey": "value"
                }
            ]
        }
    ]
}

现在我想要strip去掉每个值的所有空格和换行符JSON文件。有没有某种方法可以迭代字典以及嵌套字典和列表的每个元素？

Using pkgutil.simplegeneric()创建辅助函数get_items():

import json
import sys
from pkgutil import simplegeneric

@simplegeneric
def get_items(obj):
    while False: # no items, a scalar object
        yield None

@get_items.register(dict)
def _(obj):
    return obj.items() # json object. Edit: iteritems() was removed in Python 3

@get_items.register(list)
def _(obj):
    return enumerate(obj) # json array

def strip_whitespace(json_data):
    for key, value in get_items(json_data):
        if hasattr(value, 'strip'): # json string
            json_data[key] = value.strip()
        else:
            strip_whitespace(value) # recursive call


data = json.load(sys.stdin) # read json data from standard input
strip_whitespace(data)
json.dump(data, sys.stdout, indent=2)

Note: functools.singledispatch() http://docs.python.org/3.4/library/functools#functools.singledispatch函数（Python 3.4+）将允许使用collections' MutableMapping/MutableSequence http://docs.python.org/3/library/collections.abc.html#collections-abstract-base-classes代替dict/list here.
