Hi ! I think this does what you want:

use HTML::Tagset;

my %tags = %HTML::Tagset::isKnown;
my $tagpattern = "(".join('|',keys %tags).")";

print STDERR "$tagpattern\n";

while (<>) {
  print strip_html_tags($_);
}


sub strip_html_tags {
  my $line = shift;
  $line =~ s/<\s*$tagpattern(?:\s*>|\s+[^>]*>)([^<]*)<\s*\/\1[^>]*>/$2
+/ig;
  return $line;
}

I first create the string $tagpattern by putting a "|" between all known HTML tags and surrounding the whole thing with parantheses. This will give something like "(a|p|code.....)" and is used later in the subroutine to check for valid HTML tags.

The regex looks a bit complicated and I am sure that it can be written much better, but I believe it is sufficient for your cause.

Note that this will only work for tags that are on one line and could get you into trouble if there are < or > signs inside a tag (Don't know if this is possible in HTML).

update:

It would propably be a lot wiser to use Ovid's code then my homegrown regex.
