Glad to hear you solved it with a regex. In case it fails in the future here's my go with a parser.

#!/usr/bin/perl

use strict;
use warnings;

use HTML::TreeBuilder;

my $html = do{local $/;<DATA>};
my $r = HTML::TreeBuilder->new_from_content($html);

printf qq{*%s*\n}, $_->as_text for $r->look_down(_tag => q{b});

__DATA__
