[Pyparsing] Parsing object structure

[Claus R. <cla...@ro...>]

Hi,

i try to parse an object structure which is using open and close tags
and containing lists of another objects.

Example:

                NetSet{
                        name={LAN SIDE}
                        oid={123998333,723663,2625521122}
                        readOnly={0}
                        origin={}
                        global={0}
                        comment={Voice Server UC}
                        list={
                                NetEntry{
                                        name={}
                                        readOnly={0}
                                        origin={}
                                        global={0}
                                        comment={}
                                        addr={192.169.0.0/24}
                                }
                        }
                        neglist={
                        }
                }


I tried to start with following code structure and don't know if it
makes sense or not.

from pyparsing import *

LBRACE,RBRACE,SEMI,EQ,PCT = map(Suppress,"{};=%")
comment = SEMI + restOfLine

keyName = Word(alphas)
text = Word( alphanums, "-", ",")
text = Word(printables)
num = Word(nums)
ip = Combine(Word(nums) + ('.' + Word(nums))*3)

v_text = keyName + EQ + LBRACE + Optional(text) + RBRACE
v_num = keyName + EQ + LBRACE + Optional(num) + RBRACE
v_ip = keyName + EQ + LBRACE + Optional(ip) + RBRACE

NETENTRY = ( "NetEntry" + LBRACE + ZeroOrMore(Group(v_text | v_num |
v_ip)) + RBRACE )
NETSET_PLIST = ( "list" + EQ + LBRACE + ZeroOrMore(NETENTRY) + RBRACE )
NETSET_NLIST = "neglist" + EQ + LBRACE + ZeroOrMore(Group(NETENTRY)) +
RBRACE
NETSET = "NetSet" + LBRACE + ZeroOrMore(Group(v_text | v_num |
NETSET_PLIST | NETSET_NLIST)) + RBRACE
rule_ref = NETSET

for mr in rule_ref.parseFile("sample"):
    print mr

I get following result:

pyparsing.ParseException: Expected "}" (at char 48), (line:2, col:25)

It seems NETSET_PLIST does not work, perhaps my code is the wrong approach.

Thanks a lot
Claus
