Not to rain on anyone's parade, but this is something you don't need perl for at all -- not unless you need different data on each line. If your looking to repeat an element over and over and its completely static you have two other good choices:

• Use Server Side Includes. This requires they be turned on by your webhost. Many don't allow it for security reasons.
• Use the EMBED tag. The only real problem is only mozilla supports it properly for embedding HTML docs
• Use an IFRAME. This is prolly easiest solution
• Use the funky method described below

You can also do it with javascript... but then if the surfer has JS turned off... ouch?? So here's the JS way.

1) Make a .js doc thats all one line like this:
document.write("your HTML HERE");

2) in your main HTML doc where you want that file to be included you put the following line:
<script LANGUAGE="javascript" TYPE="text/javascript" SRC="include.js"></script>

For even MORE fun ... change the SRC to include.pl and write a perl file that dumps out 1 line of javascript which reads:
document.write("blahblahblah");

and you have a dynamic include. :-)
