Hello Monks; I am in need of your wisdom. The ultimate goal is ti create a method of validating user input. I have a script that prompts the user to enter values on the command line, (using getopts). I have a configuration file (text file) where I have a line configured to store the 'allowed values'
Example:
Tags mail, page, conf, test

I am using use Config::Simple to read this file and create an array of "allowed" values: 
open(FH, "config.txt");
 $cfg->guess_syntax(\*FH));

my @tags = $cfg->param("Tags");
  unlink $_ for @tags;

I then grab the user entry via getopts and store in an array
my @user_tags = $opt_c ; And, I use use Array::Utils qw(:all) like so... 
my @valid_tag = intersect(@user_tags, @hash_tags);
if (@valid_tag == 0){
                        die " \n\n NOTICE: TAG MISSING OR INVALID \n \
+n\n";
                } else{
                        chomp (@valid_tag);
}

This works okay as long as only a single value is passed on the command line. Example: 
$ script.p, -c "test"

But, if I pass multiple values, the verification step fails Example: 
$ script.pl -c "test page"

[download]
NOTICE: TAG MISSING OR INVALID
Any advice would be much appreciated! Thank you! Bee
