This line sets the variable buffer to everything in between the "</HEAD>" tag and the </BODY> tag in a file.  

$buffer =~ m/<\/HEAD>(.*)<\/BODY>/is;

I have a problem in that some of my documents don't have </BODY> tags and some do... I need the line to do this (here is the english)

$buffer is equal to all text in between the </HEAD> tag and either the </BODY> tag, if there is one OR this string: /commonfooter.cgi

help?

The | symbol gives you  alternation (OR) in regular expressions.
$buffer =~ m/<\/HEAD>(.*)(<\/BODY>|\/commonfooter.cgi)/is;
print($1);
