Maybe you should check the format of the HTML file you are feeding your 
script with. As you use an "\n" in your regexp, it will success only if 
there is a newline,. (The old newline debate.. :)
If your file use MacOS newlines (CR) and that you run this script under 
MacPerl, that's ok, but if you run it under DOS or Un*x, it will fail 
(because Uni*x newlines are LF and DOS are CRLF). 
The solution is to convert the file to the native platform format. 

Hopes this helps.
