Hi, guys,
I am trying to parse out the apratment number in a regular expression :
If I use
Regex regex = new
Regex(@"(?<AddressWithoutApartment>.+)(?<Apartment Seperator>\bAPT|#|UNIT\b)(?<Apartment>.+)",
RegexOptions.ExplicitCapture);
I will be able to parse out "100 main ST # C)
But if I move "#" position in regular expression, I won't be able to
parse out the same address anymore.
Regex regex = new
Regex(@"(?<AddressWithoutApartment>.+)(?<Apartment Seperator>\bAPT|UNIT\#\b)(?<Apartment>.+)",
RegexOptions.ExplicitCapture);
Any suggestion, guru.
Thanks,
JW 3 4503

The latter fails to match because there's no word boundary (\b) between
an octothorpe and a space. Remember, a word boundard occurs between a
\w and a \W or vice versa, but '#' and ' ' both match \W.
A start in the right direction is (line breaks inserted):
(?<AddressWithoutApartment>.+)
(?<ApartmentSeparator>\b(APT|UNIT)\b|#(?=\s+))
(?<Apartment>.+)
Hope this helps,
Greg
