if ( @group_vals == grep /^cs?d$/, @group_vals ) {
do { x() };

unless ( grep { !/^(?:cd|csd)$/ } @array) {

# you get all the elements of @array that are neither 'cd' nor 'csd'; if
the resulting list is empty, you enter this block

}
elsif ( grep { /^(?:cd|csd)$/ } @array and grep { !/^(?:cd|csd)$/ }
@array) {

# i.e., if the array contains at least one element being 'cd' or 'csd'
and if it also contains something that is not any of them (not sure if I
understood what you wanted, though)

Array help needed please

[William Kolln]

This is a previous message from April left unanswered.


Can Anyone Help...thanks if you can!



I have an array called group_vals.

This array can be populated by any combination of values
e.g.  /sp|lp|ep12|ffp|vid|dvd|bx|bkk|cd|csd/

I want to be able to say that:

if the array contains any combination of only the values 'cd' and/or 'csd'
then do x
otherwise
if the array contains any combination of any other value other than but also
including 'cd' and/or 'csd'
then do y
