docs: This is a convenience function to process the elements of an xml dump of
          a mysql relational database.
          The "elem" is akin to a mysql table, with it's name of ```table_name```.
          It will process each ```row``` given the ```processing_function``` supplied.
          :param elem: The element data
          :param table_name: The name of the table to process
          :param processing_function: The row processing function
          :param limit:

          although it not explicitly imported here.
