the problem is in the 'assignment' side - so you
need to have initialized
$header_html
$footer_html
to some reasonable value...
Since you are Ripping Out the 'guts' of a webPage,
the stuff inside the 'BODY' tags - you might
want to deal with all the stuff that had been inside
the <head>...</head> ...
or step back and do the basic schema approach to what
a webPage is composed of
<!DOCTYPE ....>
<html ..>
<head>
.....
</head>
<body...>
.....
</body>
</html>
so it would seem that were you trying to 'retain'
that 'form' - then you should set
$header_html to everything up to the first <body...>
and
$footer_html to the stuff including and following </body>
Prior to trying to grot out the $content....
there are several really good html parsing modules at the CPAN
my fave is the HTML::TreeBuilder stuff....
