Re: [Pyparsing] Parsing object structure

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

Ok, i changed it to the minimal set i need at the moment.
text = Word( alphanums + "," + " ")


But i have another problem with that line it seems.
NETSET = "NetSet" + LBRACE + ZeroOrMore(Group(v_text | v_num | NETSET_PLIST | NETSET_NLIST)) + RBRACE


It's referencing to NETSET_PLIST which is defined as follows:
NETSET_PLIST = ( "list" + EQ + LBRACE + ZeroOrMore(NETENTRY) + RBRACE )


Which means it should match "list={" and a few child options gut i get following message while parsing:
pyparsing.ParseException: Expected "}" (at char 302), (line:8, col:25)
