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.
