Trying to extract words from two different sources that use different conventions.

Using regex for that, I cannot create one regex that deals with both options.

If I try to extract using : or - then the first one gets extracted as

Ohare, Montrose, I, 290 Circle, IL, IL

How can I get a regex to split on : or - but ignore I- or ignore 'IL-', 'US-', 'Indiana-East-West' and many other that I may find?

What I have so far but not working as I want Regex

Answer 1

You can use this negative lookbehind regex:

(?:(?:IL?|US)-|Indiana-East-West)(*SKIP)(*F)|[:-]

Example Code:

$s = 'NB:I-894/US-45:Hale Interchange:Zoo Interchange:WI:IL';
print_r(preg_split('/(?:(?:IL?|US)-|Indiana-East-West)(*SKIP)(*F)|[:-]/' , $s));
Array
(
    [0] => NB
    [1] => I-894/US-45
    [2] => Hale Interchange
    [3] => Zoo Interchange
    [4] => WI
    [5] => IL
)
