We've had a regexp answer, but for readability I'd use the
HTML::TokeParser module. It'd work like this.
# Prep an object. $html contains the html to parse.
my $p = HTML::TokeParser->new( \$html ) or die "$!";
# Find an <a> tag, and get everything outside of it up to </a>.
my $token = $p->get_tag("a");
my $reference = $p->get_trimmed_text("/a");
# From there, find a </b> tag, and snarf everything up to <br>.
my $token = $p->get_tag("/b");
my $title = $p->get_trimmed_text("br");
You'll have some small tidying up to do on both, but it's a /much/ more
readable (and maintainable) way of parsing the HTML.
Hope this helps, (from one Manchester perl bod to another ;-)
