Simple REGEX  -  Why does this not work?

Simple REGEX:
Why does this not work? All I want is to grab the
first three lines in the first three variables and then
everything else in the fourth variable.
When I try to use ^ or $ (beginning or end of line chars)
it really doesn't work at all!
The Regex should use \n as seperation char.

Thanks for any help!

--------------- snip ------------------


#!\perl\bin\perl.exe

my $element =
"LineOne
LineTwo
LineThree

Line here
Line this and that
Line some more

";

my ($var1,$var2,$var3,$var4) = ($element =~ m/(.*?)\n(.*?)\n(.*?)\n(.*)/);

print "Line1=".$var1."\n";
print "Line2=".$var2."\n";
print "Line3=".$var3."\n";
print "TheRest=".$var4."\n\n";

use this:

@lines = split (/\n/, $element, 4);

To make the regex work, use the /s modifier
