Simple xml serializer.
@author Reimund Trost 2013
Example:
mydict = {
'name': 'The Andersson\'s',
'size': 4,
'children': {
'total-age': 62,
'child': [
{ 'name': 'Tom', 'sex': 'male', },
{
'name': 'Betty',
'sex': 'female',
'grandchildren': {
'grandchild': [
{ 'name': 'herbert', 'sex': 'male', },
{ 'name': 'lisa', 'sex': 'female', }
]
},
}
]
},
}
print(dict2xml(mydict, 'family'))
Output:
<family name="The Andersson's" size="4">
<children total-age="62">
<child name="Tom" sex="male"/>
<child name="Betty" sex="female">
<grandchildren>
<grandchild name="herbert" sex="male"/>
<grandchild name="lisa" sex="female"/>
</grandchildren>
</child>
</children>
</family>

It's quite simple, and enough for simple situations. I like simple code.
