Rational Rose ".ptl" file parsing?

[Mike C. Fletcher]

Well, the "lisp.py" example from simpleparse seems to parse it fine, but 
all you get out is a set of "name", "string", "list" and "number" 
records (in a tree) (i.e. the parser's just giving you what lisp 
structures were found).  You'd have to interpret the results yourself 
regarding what each name is *meaning*. 

The grammar is pretty simple from what you've shown, you could probably 
hand-code it as easily as using a parser.

Enjoy yourself,
Mike

Here's what you get on a small sample string (note that everything below 
"float" is ignorable in most cases):

success '(object Design "Logical View"\n    is_unit    \tTRUE\n    
is_loaded  \t(test this 2.3456))' 86
  'list' :  '(object Design "Logical View"\n    is_unit    \tTRUE\n    
i... (0, 86)
  | 'name' :  'object' (1, 7)
  | 'name' :  'Design' (8, 14)
  | 'string_double_quote... :  '"Logical View"' (15, 29)
  | | 'char_no_quote' :  'Logical View' (16, 28)
  | 'name' :  'is_unit' (34, 41)
  | 'name' :  'TRUE' (46, 50)
  | 'name' :  'is_loaded' (55, 64)
  | 'list' :  '(test this 2.3456)' (67, 85)
  | | 'name' :  'test' (68, 72)
  | | 'name' :  'this' (73, 77)
  | | 'number_expr' :  '2.3456' (78, 84)
  | | | 'number' :  '2.3456' (78, 84)
  | | | | 'float' :  '2.3456' (78, 84)
  | | | | | 'explicit_base' :  '2.3456' (78, 84)
  | | | | | | 'int_unsigned' :  '2' (78, 79)
  | | | | | | 'decimal_fraction' :  '.3456' (79, 84)
  | | | | | | | 'int_unsigned' :  '3456' (80, 84)
