I've been lurking along as you run this problem to ground. The syntax you

had writing a generic street address parser with pyparsing

last citation ie. 463 U.S. 29, 43, 103 S.Ct. 2856,
2867, 77 L.Ed.2d 443 (1983). I tested it on another sample text and it missed
the last citation too.

I found a list of words before the first word that can be removed which I think
is the only way to successfully parse the citations. Here they are:

Cf. | See Generally | Citing | In |

Here is my stab at it, using regular expressions. Any comments welcome.
I had to use two regexes, one to find all citations, and the other one
I guess I'm in the mood for a parsing challenge this weekend, I wrote
a PLY version of the citation parser, see attached. It generates
exactly the output you asked for except for the inclusion of "In" in
the name.

I didn't know about pyparsing which appears to be very powerful and have joined
their list. Thank-you for your help.

As I've been reading along, I've been thinking that the word "In" qualifies
as a "magic
It turns out you can use Or expressions to cause a kind of
backtracking in Pyparsing. This is very close to what you want:
Name1 = Forward()
Name1 << Combine(Word(alphas) + Name1 | Word(alphas) + Suppress('v.'),
joinString=' ', adjacent=False).setResultsName('name1')
Name2 = Combine(OneOrMore(Word

Okay, I'd better get to grips with pyparsing!
