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).


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