Pyparsing has built-in support for special treatment of quoted
strings. Observe:
from pyparsing import *
data = r'abc "xy z" "1 2 3" "a \" x"'
quotedString.setParseAction(removeQuotes)
print OneOrMore(quotedString |
Word(printables) ).parseString(data)
prints:
['abc', 'xy z', '1 2 3', 'a \\" x']
Or perhaps a bit trickier, do the same while skipping items inside /*
*/ comments:
data = r'abc /* 456 "xy z" */ "1 2 3" "a \" x"'
quotedString.setParseAction(removeQuotes)
print OneOrMore(quotedString |
Word(printables) ) \
.ignore(cStyleComment).parseString(data)
prints:
['abc', '1 2 3', 'a \\" x']
