[Pyparsing] Continue parsing on mismatches

[donn <don...@gm...>]

Hi,
How would I get PP to *continue* parsing a string, skipping over any 
mismatched (badly formed) patterns? Raising an exception that I can then 
continue from would be a bonus.


Here's my best effort so far to demo the thing:
-----

import pyparsing as PP

dot = PP.Literal(".")
comma = PP.Literal(",").suppress()

## A single digit like 0 really means 0.0 so the .0 is optional:
numberMaybeDotnumber = PP.Combine( PP.Word(PP.nums) + PP.Optional( dot + 
PP.Word(PP.nums) ) )

## I have seen Inkscape include E- in the string... e.g 0.8683224E-07, 
hence all the gumph in floater.
floater = PP.Combine(PP.Optional("-") + numberMaybeDotnumber + 
PP.Optional( PP.Literal("E") + PP.Literal("-") + PP.Word(PP.nums) ) )
floater.setParseAction(lambda toks:float(toks[0]))

open_bracket=PP.Literal("(").suppress()
close_bracket = PP.Literal(")").suppress()

opt_couple = PP.Optional( comma + floater + comma + floater )

## rotate( angle (,x,y) ) where ,x,y are optional.
rotate_command = "rotate" + open_bracket + PP.Group( floater + 
opt_couple ) + close_bracket

matrix_commands = rotate_command

phrase_matrix = PP.OneOrMore(PP.Group(matrix_commands))

##  right           wrong         right
##              PP stops here
##              with no error.
##                            I want this too
s="rotate(5,5,6) rotate(99,7) rotate(7)"

print phrase_matrix.parseString(s)

## swapped wrong/right at end to test.
s="rotate(5,5,6) rotate(99) rotate(7,7)"
print phrase_matrix.parseString(s)

-----

Output:
[['rotate', [5.0, 5.0, 6.0]]]
[['rotate', [5.0, 5.0, 6.0]], ['rotate', [99.0]]]

rotate( arg1 ) is okay.
rotate( arg1, arg2, arg3) is okay.
rotate( arg1,arg2 ) is wrong. I want to skip over that like it was never 
there (or raise an warning).
(same for rotate( ..empty.. ) and other mad patterns.)
