Excellent! flaviodesousa solution works for explicitly defined arrays

my @Array1 = qw{XXX FFF ZZZ AAA BBB QQQ LLL JKK III CCC DDD DCD};
my @Array2 = ("XXX BBB AAA CCC DDD EEE", "FFF NNN JKK III LLL QQQ");

XXX IS found in XXX BBB AAA CCC DDD EEE
XXX IS NOT found in FFF NNN JKK III LLL QQQ
FFF IS NOT found in XXX BBB AAA CCC DDD EEE
FFF IS found in FFF NNN JKK III LLL QQQ

However my arrays are being read in from a text file 
my $file1 = '/tmp/file1.txt';
my @Array1;

open FILE, $file1 or die $!;

while(<FILE>)
{
        @Array1 = <FILE>;
}

my $file2 = '/tmp/file2.txt';
my @Array2;

open FILE, $file2 or die$!;
while(<FILE>)
{
        @Array2 = <FILE>;
}

print @Array1;
Print @Array2;

/tmp/file1.txt is as stated above 
XXX
FFF
ZZZ
AAA
BBB
QQQ
LLL
JKK
III
CCC
DDD
DCD

/tmp/file2.txt is 
XXX BBB AAA CCC DDD EEE
FFF NNN JKK III LLL QQQ

[download]

This outputs 
FFF
ZZZ
AAA
BBB
QQQ
LLL
JKK
III
CCC
DDD
DCD
FFF NNN JKK III LLL QQQ

So it looks the method I am reading in the Arrays is not as thorough as I expect it to be.
