add_action('the_content', function ($content){

    // look for <h1> tags and text therein, anticipate class/id name
    $findH1s = preg_match_all('/<h1 ?.*>(.*)<\/h1>/i', $content, $h1s);

    // if found, show above content
    if (is_array($h1s) && isset($h1s[0]))   
        return "<pre>H1's in this post: ".print_r( $h1s[0] ,true)."</pre>".$content;
