You use a hash for holding your elements to check against and use the values
within the array as a key to know whether it is a hit or not. If unsure on
how data coming in, then make sure you use a lc or uc against your data and
the data coming in, unless CAP is different from cap.
Wags ;) ps following not tested but should be close
#!perl -w
use strict;
my %possible_matches = ('list', 1, 'of',1, 'items',1, 'to',1, 'match',1,
'against',1 ); # Hash comes in sets of two ( key/Value )
@list = qw( imagine that there is an unknown number of elements in here
);
foreach my $MyKey (@list) {
if ( exists $possible_matches{$MyKey} ) {
# exists
}else {
# does not exist
}
}

Subject: Matching one array against another
I have a question that to me seems like it would be part of the foundation
of Perl.
@possible_matches = qw( list of items to match against );
@list = qw( imagine that there is an unknown
number of elements in here );
foreach $list (@list) {
# now match againt each value in @possible_matches, one-by-one,
}
Is this not possible?
