Regex matching character within

Question

Looking to match WS-810-REFERENCE-1 where the string must have -'s within it

And can't think of something to work perfectly [a-zA-Z0-9\-]+

That will match but will also match words that do not have the - character

Thought of maybe this ([a-zA-Z0-9\-]+\-)+ But that will match WS-810-REFERENCE- missing the final segment.

Thoughts?

I believe you're looking for lookahead to make sure hyphen is present in the string. You can use:

\b(?=\w*?-)[a-zA-Z0-9-]+(?= |$)

Matching only words not entire lines, so I tried (?=.*?-)[a-zA-Z0-9-]+ but that also matches strings without hyphens – NMGod Mar 12 '14 at 05:11

Used a modified version of the second attempt just to grab that extra missing section ((?:[a-zA-Z0-9]+\-)+[a-zA-Z0-9]+)
