Hi,
I'd use the $/ (a.k.a. $INPUT_RECORD_SEPARATOR) variable to set to the line that separates the html pages and read one "page" at a time: 
#!/usr/bin/perl

use strict;
use warnings;

$/ = '---this line is the separator---';

while (<DATA>) {
    $_ =~ s#$/##; # strip the separator line
    print "Data to process: \n$_\n";
}


__DATA__
<html>
  <body>file 1</body>
</html>
---this line is the separator---
<html>
  <body>file 2</body>
</html>
---this line is the separator---
<html>
  <body>file 3</body>
</html>
---this line is the separator---
<html>
  <body>file 4</body>
</html>
---this line is the separator---
<html>
  <body>file 5</body>
</html>
---this line is the separator---
