You can traverse content_list of any element. Text is plain, while other tags are references.

        ...
        for my $part ($div->content_list) {
            print $part,"\n"
                if !ref($part);
        }
        ...

If you want all text (including inner tags), you can use as_text method of elements. In this case it would also return title and date, but generally it is useful.
