Just to satisfy any curiosity you might have, it's the Penn TreeBank
format: http://www.cis.upenn.edu/~treebank/
(Except that the actual Penn Treebank data unfortunately differs from
the format spec in a few ways.)

Wow, this is a pretty dense pyparsing program. You are really pushing
the envelope in your use of ParseResults, dicts, etc., but pretty much
everything seems to be working.
I still don't know the BNF you are working from, but here are some
other "shots in the dark":

If your word char set is just alphanums+"-", then this will work
without doing anything unnatural with leaveWhitespace:
from pyparsing import *
thing = Word

Thanks, that's exactly what I was

Thanks for giving pyparsing a try! To see whether your input text
consumes the whole string, add a StringEnd() element to the end of your
BNF. Then if there is more text after the parsed text, parseString
will throw a ParseException.
I notice you call leaveWhitespace on several of your
How do I make sure that my entire string was parsed when I call a
pyparsing element's parseString method? Here's a dramatically
simplified version of my problem:
py> import pyparsing as pp
py> match = pp.Word(pp.nums)
py> def parse_num(s, loc, toks):
... n, = toks
... return int(n) + 10
