Here's what I came up with, based on the discussion: 
use HTML::TokeParser::Simple;


sub remove_final_blockquotes
{
    my $html_string = shift;
    $html_string =~ s/\s+$//smg;        # remove trailing whitespace
    
    my $qty_blockquote = 0;
    my $scratch_pad = '';
    my $parser = HTML::TokeParser::Simple->new(string => $html_string)
+;
    $parser->unbroken_text(1);
    my $ret = '';
    
    while (my $token = $parser->get_token)
    {
        if ($token->is_start_tag('blockquote'))
        {
            $qty_blockquote++;
            #$ret .= "\nqty_blockquote-> $qty_blockquote";
        }
        
        if (! $qty_blockquote)
        {
            
            $ret .= $scratch_pad;        # We've left the blockquote, 
+so add it
                                        
            $scratch_pad = '';
            $ret .= $token->as_is();
        } else {
            $scratch_pad .= $token->as_is();
        }
        
        if ($token->is_end_tag('blockquote'))
        {
            $qty_blockquote--;
            #$ret .= "\nqty_blockquote-> $qty_blockquote";
        }
    }
    
    return $ret;
}
