""" Returns the given attribute as a string.
The key parameter determines how the value is formatted before
returning. To refer to sub attributes, use '+' to add more keys
(e.g. 'name+ref' will access obj['name']['ref']). A '!' introduces
a formatting suffix. If no suffix is given, the value will be
converted using the str() function.
Available formatters:
!:... - use a formatting expression according to Python Mini Format Spec
!i - make case-insensitive comparison
!fm - consider comparison string a regular expression and match full value
