Describe the bug

  File "../Library/Python/3.8/lib/python/site-packages/dicttoxml.py", line 333, in convert_kv
    attr['type'] = get_xml_type(val)
TypeError: 'bool' object does not support item assignment

To Reproduce

 def testJson2XML(self):
        ''' test Json  XML conversion '''
        jsonText='{"count": 1, "events": [{"acronym": "EuroPar 2020", "city": "Warsaw", "country": "Poland", "creation_date": "2020-02-27T14:44:52+00:00", "end_date": "2020-08-28T00:00:00+00:00", "event": "EuroPar 2020", "foundBy": "EuroPar 2020", "homepage": "https://2020.euro-par.org/", "modification_date": "2020-02-27T14:44:52+00:00", "series": "EuroPar", "source": "OPEN RESEARCH", "start_date": "2020-08-24T00:00:00+00:00", "title": "International European Conference on Parallel and Distributed Computing", "url": "https://www.openresearch.org/wiki/EuroPar 2020"}]}'
        xml=json2xml.Json2xml(jsonText).to_xml()  
        print(xml)

Expected behavior
should not fail

Hi @WolfgangFahl. Thanks for reporting this issue. I just tried to reproduce this issue. Looks like your code is either using an old version of the documentation.

First of all, make sure you are using a more recent version of json2xml. The latest one now is json2xml (3.4.1) - Simple Python Library to convert JSON to XML

So either install it directly like this: pip install json2xml==3.4.1 or upgrade pip install --upgrade json2xml. Then verify if you have the latest json2xml before proceeding any further. The output should be like this:

pip freeze | grep json2xml
json2xml==3.4.1

Now, looking at your example, this is how the correct code would look like:

from json2xml import json2xml 
from json2xml.utils import readfromurl, readfromstring, readfromjson 

# we have a method to read the json string now
data =   readfromstring('{"count": 1, "events": [{"acronym": "EuroPar 2020", "city": "Warsaw", "country": "Poland", "creation_date": "2020-02-27T14:44:52+00:00", "end_date": "2020-08-28T00:00:00+00:00", "event": "EuroPar 2020", "foundBy": "EuroPar 2020", "homepage": "https://2020.euro-par.org/", "modification_date": "2020-02-27T14:44:52+00:00", "series": "EuroPar", "source": "OPEN RESEARCH", "start_date": "2020-08-24T00:00:00+00:00", "title": "International European Conference on Parallel and Distributed Computing", "url": "https://www.openresearch.org/wiki/EuroPar 2020"}]}')

xml = json2xml.Json2xml(data).to_xml() 
print(xml)

Which returns:

<?xml version="1.0" ?>
<all>
	<count type="int">1</count>
	<events type="list">

Thx. I also fixed the problem with the upstream dict2xml library which was the initial culprit of the error message.
i dont really need json2xml since i can get access to the original objects and their dicts ...

See
http://ptp.bitplan.com/parse?titles=EuroPar+2020&examples=example1&format=xml

from dicttoxml import dicttoxml
from xml.dom.minidom import parseString

def asXml(self,result,pretty=True):
        ''' convert result to XML'''
        events=[]
        for title in result:
            for event in title.events:
                events.append(event.__dict__)
        item_name = lambda x: "event"        
        xml=dicttoxml(events, custom_root='events',item_func=item_name, attr_type=False)
        if pretty:
            dom=parseString(xml)
            prettyXml=dom.toprettyxml()
        else:
            prettyXml=xml    
        return prettyXml
