The first mistake most make when creating a complex regex is to use $1,$2, et al. Just capture everything into an array. This is not guaranteed to work for everything you throw at it, but it works for the data you have given:
my @line; foreach my $line (@data_file) { @line = $line =~ / (\d+)\s+ # first numbers ([^\d]+) # full name (.*)?(?:\w\w)\s+ # street address (\w\w)\s+ # state (\d{5})\s+ # zip (\d{3}-\d{3}-\d{4})\s+ # phone (.*) # the rest /x; print join('|',@line),"\n"; }
And here is a play by play breakdown ;)
  • (\d+)\s+: one or more digits followed by at least one white space
  • ([^\d]+): everything up to a digit
  • (.*)?(?:\w\w)\s+: tricky (and fragile) - this gets everything up to two consecutive alphas that are followed by at least one whitespace
  • (\w\w)\s+: two consecutive alphas followed by at least one whitespace
  • (\d{5})\s+: exactly 5 digits followed by at least one whitespace
  • (\d{3}-\d{3}-\d{4})\s+: you get the picture ;)
Hope this helps, anything more might require something smarter like Parse::RecDescent.
