Dict2XML

Python tool useful to convert a JSON-style dictionary element to a XML document.

How? Show me...

Basic example

from dict2xml import dict2XML
json = {'street': {
    'name': '4th street',
    'city': 'Rio de Janeiro',
    'dwellers': '200'
}}
print dict2XML(json)

gives:

<?xml version="1.0" ?>
<street>
  <city>Rio de Janeiro</city>
  <dwellers>200</dwellers>
  <name>4th Street</name>
</street>

Notice that a python dictionary doesn't record the order of its keys, therefore there is a feature to order your data when it matters.

json = {'street': {
    '1__name': '4th street',
    '2__city': 'Rio de Janeiro',
    '3__dwellers': '200'
}}
print dict2XML(json)

gives:

<?xml version="1.0" ?>
<street>
  <name>4th Street</name>
  <city>Rio de Janeiro</city>
  <dwellers>200</dwellers>
</street>

You can also generate it with no indentation or linebreaks...

print dict2XML(json, indent=False)

gives:

<?xml version="1.0" ?><street><name>4th Street</name><city>Rio de Janeiro</city><dwellers>200</dwellers></street>

... or encoded with UTF-8.

json = {'street': {
    u'1__name': u'4th street',
    u'2__city': u'São Paulo',
    u'3__dwellers': u'200'
}}
print dict2XML(json, utf8=True)

gives:

<?xml version="1.0" encoding="utf-8"?>
<street>
  <name>4th Street</name>
  <city>São Paulo</city>
  <dwellers>200</dwellers>
</street>

Nested dictionaries

from dict2xml import dict2XML
json = {'street': {
    '1__name': '4th street',
    '2__city': 'Rio de Janeiro',
    '3__dwellers': {
        '1__dweller1': {
            'name': 'Lucas',
            'age': '23'
        },
        '2__dweller2': {
            'name': 'Renata',
            'age': '25'
        },
        '3__dweller3': {
            'name': 'Rafael',
            'age': '55'
        }
    }
}}
print dict2XML(json)

gives:

<?xml version="1.0" ?>
<street>
  <name>4th Street</name>
  <city>Rio de Janeiro</city>
  <dwellers>
    <dweller1>
      <age>23</age>
      <name>Lucas</name>
    </dweller1>
    <dweller2>
      <age>25</age>
      <name>Renata</name>
    </dweller2>
    <dweller3>
      <age>55</age>
      <name>Rafael</name>
    </dweller3>
  </dwellers>
</street>

Lists

Useful to create multiple entries of an element. Lists are ordered, there's no need to use any extra feature.

from dict2xml import dict2XML
json = {'street': {
    '1__name': '4th street',
    '2__city': 'Rio de Janeiro',
    '3__dwellers': {
        'dweller': [
            {
                '1__name': 'Lucas',
                '2__age': '23'
            },
            {
                '1__name': 'Renata',
                '2__age': '25'
            },
            {
                '1__name': 'Rafael',
                '2__age': '55'
            }
        ]
    }
}}
print dict2XML(json)

gives:

<?xml version="1.0" ?>
<street>
  <name>4th Street</name>
  <city>Rio de Janeiro</city>
  <dwellers>
    <dweller>
      <name>Lucas</name>
      <age>23</age>
    </dweller>
    <dweller>
      <name>Renata</name>
      <age>25</age>
    </dweller>
    <dweller>
      <name>Rafael</name>
      <age>55</age>
    </dweller>
  </dwellers>
</street>

Element attributes

Easy to do. Instead of passing the content of an element as the value of the key, pass a 2-tuple in which the second element is the content. The first will be the attributes. For the lists, pass individual set of attributes for each value of the list.

from dict2xml import dict2XML
json = {'street': {
    '1__name': '4th street',
    '2__city': ({'country': 'Brazil'}, 'Rio de Janeiro'),
    '3__dwellers': {
        'dweller': [
            ({'id': '1'}, {
                '1__name': 'Lucas',
                '2__age': '23'
            }),
            ({'id': '2'}, {
                '1__name': 'Renata',
                '2__age': '25'
            }),
            ({'id': '3'}, {
                '1__name': 'Rafael',
                '2__age': '55'
            })
        ]
    }
}}
print dict2XML(json)

gives:

<?xml version="1.0" ?>
<street>
  <name>4th Street</name>
  <city country="Brazil">Rio de Janeiro</city>
  <dwellers>
    <dweller id="1">
      <name>Lucas</name>
      <age>23</age>
    </dweller>
    <dweller id="2">
      <name>Renata</name>
      <age>25</age>
    </dweller>
    <dweller id="3">
      <name>Rafael</name>
      <age>55</age>
    </dweller>
  </dwellers>
</street>
