Define "actually works". Whatever you think the code is doing, that isn't what it is actually doing. A better approach is to use subs:

use strict;
use warnings;

package Stuff;

sub xmlheader {
print "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
}

sub xmldtd {
print "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"ht
+tp://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">
<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"en\" lang=\"en
+\">
<head>
    <meta http-equiv=\"content-type\" content=\"application/xhtml+xml;
+ charset=utf-8\" />\n";
}

package main;

print "content-type:text/html; charset=utf-8\n\n";

Stuff::xmlheader ();
Stuff::xmldtd ();

Note that adding strictures (use strict; use warnings; - see The strictures, according to Seuss) to your code would have turned up most of the bugs due to misunderstanding of what was going on.
