First, this contains a syntax error. Please test your code before you
post.
Try:
$_ = '"435" "" "634"';
my $capture_inside_dq = qr/ \" ( [^"]* )\" /x;
my ( $one, $two, $three ) = / \A $capture_inside_dq \s
$capture_inside_dq \s $capture_inside_dq \z /x;
print "one = '$one'\n";
print "two = '$two'\n";
print "three = '$three'\n";
