( #3333=superdoc: print w/replies, xml ) Need Help??

Once upon a time I tried to parse addresses and came up with some fugly code. You'd first want to check out Lingua::EN::AddressParse and see if you can use it as-is or modify it to suit your needs. If all else fails here's the code I was using. Keep in mind this is two files. unabbrev.pm takes the standard US postal service abbreviation and expands them. parse_address.pl probably read one address per line. You will definately need to modify this to use it.

Also, this is not how you should program. The prototypes should go, the direct access of @_, etc. Don't use this as a style guide. Please. This is not how I write perl anymore. For production or otherwise. Ugly, ugly, ugly.

# unabbrev.pm # Fixed the unabbrev.pm file up some. sub uword { join ' ', map unabrev($_), split ' ', shift; } sub unabrev { local $_ = shift; return $_ unless /\w/; # One really big expression s/^e$/east/ or s/^w$/west/ or s/^(?:n|no)$/north/ or s/^(?:s|so)$/south/ or s/^ne$/north east/ or s/^nw$/north west/ or s/^se$/south east/ or s/^sw$/south west/ or s/^(?:avs|aves)$/avenue south/ or s/^beachrd$/beach road/ or s/^ccedar$/cedar/ or s/^(?:adn|add'n)$/addition/ or s/^appache$/apache/ or s/^apt$/apartment/ or s/^apts$/apartments/ or s/^(?:av|ave)$/avenue/ or s/^(?:bch|bchch|beac)/beach/ or s/^(?:bx|b0x)/box $1/ or s/^blvd$/boulevard/ or s/^brg$/burg/ or s/^bldg$/building/ or s/^cen$/center/ or s/^(?:centeral|cental)$/central/ or s/^char$/character/ or s/^chas$/chase/ or s/^ches$/chesapeake/ or s/^chig$/chicago/ or s/^cir$/circle/ or s/^(?:cty|co|cnty)$/county/ or s/^(?:ct|crt|cour)/court/ or s/^cr$/curve/ or s/^crk$/creek/ or s/^crl$/curl/ or s/^(?:crystaln|crytl)$/crystal/ or s/^ctr$/center/ or s/^dist$/district/ or s/^(?:drv|drve|dr)$/drive/ or s/^est$/estate/ or s/^fst$/forest/ or s/^ft$/fort/ or s/^(?:govt|govern|gov't)$/government/ or s/^(?:grv|grov)$/grove/ or s/^hgld$/highland/ or s/^hglds$/highlands/ or s/^(?:hgt|hht|height|ht|hghtss|hghts)$/heights/ or s/^(?:hy|hyw|hwy)$/highway/ or s/^isl$/island/ or s/^(?:jct|jction|jctn|junctn|juncton)$/junction/ or s/^(?:jctns|jcts)$/junctions/ or s/^l00p$/loop/ or s/^(?:lk|lak)$/lake/ or s/^lks$/lakes/ or s/^li'l$/lil/ or s/^(?:la|lanes|ln)$/lane/ or s/^ml$/mill/ or s/^mls$/mills/ or s/^mkt$/market/ or s/^(?:mt|mnt)$/mount/ or s/^mpls$/minneapolis/ or s/^(?:mtn|mntain|mntn)$/mountain/ or s/^(?:mntns|mtns)$/mountains/ or s/^(?:nth|nrth)$/north/ or s/^nrthbrk$/northbrook/ or s/^(?:unorg|unorgized)$/unorganized/ or s/^ph$/penthouse/ or s/^(?:pk|prk)$/park/ or s/^(?:pkwy|parkwy|pkway|pky)$/parkway/ or s/^pl$/place/ or s/^plaz$/plaza/ or s/^(?:pobox|po)$/box/ or s/^prct$/precinct/ or s/^pres$/president/ or s/^pt$/point/ or s/^pts$/points/ or s/^qtr$/quarter/ or s/^qtrs$/quarters/ or s/^(?:r|rt)$/route/ or s/^rd$/road/ or s/^rdg$/ridge/ or s/^resor$/resort/ or s/^(?:ri|rv|riv|rvr)$/river/ or s/^(?:rte|rr|rural)$/route/ or s/^(?:rs|rst)$/rest/ or s/^rverview$/riverview/ or s/^(?:shr|shoar)$/shore/ or s/^(?:shoars|shrs)$/shores/ or s/^(?:spgs|spngs|sprngs)$/springs/ or s/^(?:st|str)$/street/ or s/^svc$/service/ or s/^terr$/terrace/ or s/^twp$/township/ or s/^(?:tr|trl|trails|trls)$/trail/ or s/^trlr$/trailer/ or s/^vac$/vacation/; return $_; } 1; # address_parse.pl #!/usr/bin/perl $ID = 0; $ADDRESS = 1; while ($record = <>) { ($id,$address) = split /\t/, $record; @words = split /\s+/, $address; %record = (); HOUSE: if ($words[0] =~ /^\d+$/) { $record{house} = shift @words; ($record{odd}) = (($record{house} % 2) == 0 ?
