Convert JSON to XML in Python

Question

I see a number of questions on SO asking about ways to convert XML to JSON, but I\'m interested in going the other way. Is there a python library for converting JSON to XML?

If you don't have such a package, you can try:

def json2xml(json_obj, line_padding=""):
    result_list = list()

    json_obj_type = type(json_obj)

    if json_obj_type is list:
        for sub_elem in json_obj:
            result_list.append(json2xml(sub_elem, line_padding))

        return "\n".join(result_list)

    if json_obj_type is dict:
        for tag_name in json_obj:
            sub_obj = json_obj[tag_name]
            result_list.append("%s<%s>" % (line_padding, tag_name))
            result_list.append(json2xml(sub_obj, "\t" + line_padding))
            result_list.append("%s" % (line_padding, tag_name))

        return "\n".join(result_list)

    return "%s%s" % (line_padding, json_obj)

For example:

s='{"main" : {"aaa" : "10", "bbb" : [1,2,3]}}'
j = json.loads(s)
print(json2xml(j))

Result:

        
                10
        
        
                1
                2
                3
