in reply to Regex During Map Function

You can use grep to filter out empty values

%params = map { $_ => join("; ", grep {$_} split("\0", $cgi->Vars->{$_})) } $cgi->param;

    Remember, however, that '0' is false, hence will be filtered out. Better, perhaps, to use
        grep { length $_ }

    I don't want to filter out all empty values, though. Just the leading of a multi-valued element.

    If a form control has a bunch of checkboxes w/ the same element name, I want them all. I also want the blank values for those elements that don't have multiple values.

    For some reason there's an empty value for a multi-valued list control.
