Supports item (int, float, bool, str, unicode, datetime) and collection (list, set and dict) data types with arbitrary nesting for the collections. Datetime objects are converted to ISO format strings.
The root object passed into the dict2xml function can be any of the following data types: int, float, str, unicode, datetime, list, set, dict.
To satisfy XML syntax, by default it wraps all the dict keys/elements and values in a <root> … </root> element. However, this can be disabled to create XML snippets.
For lists of items, if each item is also a collection data type (lists, dict), the elements of that item are wrapped in a generic <item> … </item> element.
Elements with an item data type (int, float, bool, str, datetime, unicode) include a type attribute with the data type. Note: datetime data types are converted into ISO format strings, and unicode and datetime data types get a str attribute.
Elements with an unsupported data type raise a TypeError exception.
