.. autoexception:: amazonproduct.errors.AWSError
+Sometimes you may still want to access the original response. An example::
+ result = api.item_lookup(
+ ['644209004461', '009800895250', '301357583001'], IdType='UPC')
+ except InvalidParameterValue, e:
+ print 'There was an invalid ItemId!' # '301357583001'
+Although UPC ``301357583001`` will cause an error to be raised, you can
+retrieve the parsed response (here ``result`` is simply replaced with
+``e.xml``) and continue working on it as if nothing has happened.
