The parser doesn't have to be perfect, but it should
reliably reports when it fails. Then I can run the hard cases through
one of the commercial online address standardizers. I'd like to
be able to knock off the easy cases cheaply.
What I want to do is to first extract the street number and
undecorated street name only, match that to a large database of US businesses
stored in MySQL, and then find the best match from the database
hits. So I need reliable extraction of undecorated street name and number. The
other fields are less important.
