Q&A  > regular expressions


Description:

If someone enters something that SHOULD be in the hash, but isn't, how could I use a regexp to test to see what values closely match it and return those values. (the values will only be matched against the keys)

Match against the keys of the hash.

But you might be in luck: CPAN has Tie::Hash::Approx and Tie::Hash::Regex, one of which might be suitable for you.

grep {/$regex/} keys %hash
