Thanks to both of you. I figured it out based on your comments. This is what I did: 
 
my $text = qw/test4/;
$test4 = $entry->getElementsByTagName( $text)->item(0);
if (defined $test4) {
    $test4 = $entry->getElementsByTagName( $text)->item(0)->getFirstCh
+ild->getNodeValue;
}

Reps to both of you!
