more tag hack

Hi all!
I have expirenced some problems while using the “more tag” feature of wordpress 2.5. Specifically, it happens that when I want to use the “more” feature to divide this text:

<div>
some text

other text
</div>

wordpress produces this output

<div>
some text

which obviously breaks my layout.
A quirk trick to workaround this problem is this:

Add this function somewhere in your function.php file (usually located in your own style’s directory, under wp-content/themes/YOURLOOK/functions.php)

function close_dangling_tags($html){
  #put all opened tags into an array
  preg_match_all("#<([a-z]+)( .*)?(?!/)>#iU",$html,$result);
  $openedtags=$result[1];
  asort($openedtags);

  #put all closed tags into an array
  preg_match_all("#</([a-z]+)>#iU",$html,$result);
  $closedtags=$result[1];
  asort($closedtags);  

  $len_opened = count($openedtags);
  for($i=0;$i < $len_opened;$i++) {
    if ($openedtags[$i]!="" && !in_array($openedtags[$i],$closedtags)){
      $html .= '</'.$openedtags[$i].'>';
    }
  }

  $len_closed = count($closedtags);
  for($i=0;$i < $len_opened;$i++) {
    if ($closedtags[$i]!="" && !in_array($closedtags[$i],$openedtags)){
      $html = '<'.$closedtags[$i].'>' . $html;
    }
  }

  return $html;
}

And add this lines, where the more tag is causing you problem. You’ll usually have to replace the <?php the_content(); ?> block with the following one, search and replace for it in the file wp-content/themes/YOURLOOK/index.php)

old block

<?php the_content(); ?>

new block

<?php
						 ob_start();
							the_content('(Continua...)');
					    	$the_content_text = ob_get_contents();
					    ob_end_clean();
						echo close_dangling_tags($the_content_text); ?>

It works. It would be very useful to build up a single plugin based on this hack, if you’d like to do it, then you’re welcome!
