With simpleparse:
----------------------------------------------------------
from simpleparse.parser import Parser
from simpleparse.common import strings
from simpleparse.dispatchprocessor import DispatchProcessor, getString
grammar = '''
text := (quoted / unquoted / ws)+
quoted := string
unquoted := -ws+
ws := [ \t\r\n]+
'''
class MyProcessor(DispatchProcessor):
def __init__(self, groups):
self.groups = groups
def quoted(self, val, buffer):
self.groups.append(' '.join(getString(val, buffer)
[1:-1].split()))
def unquoted(self, val, buffer):
self.groups.append(getString(val, buffer))
def ws(self, val, buffer):
pass
groups = []
parser = Parser(grammar, 'text')
proc = MyProcessor(groups)
parser.parse(TESTS[1][1][0], processor=proc)
print groups
