Simple RegEx Pattern- Help with the last bit
Posted: Wed Oct 19, 2011 7:36 am
Hi All
Need a little help with my RegEx, I am half way there but can't figure out the last bit
I want the Regex to match.
123-456-789
I don't mind how long the numbers are, but the dashes in the middle can only be 1 long
My regex so far
([^-]([0-9]+[^-]))
This matches
123-456-789
but will also match
123-456----789
I just need the Regex to only allow 1 dash in the middle
Thanks for any help
