Question

I am trying to create a json file from an input xml file using xmltodict with the following code

import io, xmltodict, json
infile = io.open(filename_xml, 'r')
outfile = io.open(filename_json, 'w')
o = xmltodict.parse( infile.read() )
json.dump( o , outfile )

the last line get me the following error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 182, in dump
    fp.write(chunk)
TypeError: must be unicode, not str

I guess I need to change the encoding. My initial xml file seems to be ascii. Any idea on how to make this work?
Thanks

You can open the file in binary mode

outfile = io.open(filename_json, 'wb')

This will allow str as well.
