to wrap alternate paragraphs in tags

[peppericious]

I need to mark up a lot of dialogues, which will be created on an ongoing basis. Every second paragraph will be spoken by alternate participants in the dialogue.

 

The dialogues will always be like this, with the participants' names at the start of the paragraphs...

 

<p>Joe: Humpty Dumpty sat on a wall. Humpty Dumpty had a great fall...</p>
<p>Jill: The Grand Ol' Duke of York, he had ten thousand men...</p>
<p>Joe: And so on and so forth</p>
<p>Jill: And whatever the weather</p>

But they will need to be marked up like this:

<div class='dlg'>
	<div class='person_1'>Joe</div>
	<div class='spk_1'>Humpty Dumpty sat on a wall. Humpty Dumpty had a great fall...</div>
</div>
<div class='dlg'>
	<div class='person'>Jill</div>
	<div class='spk'>The Grand Ol' Duke of York, he had ten thousand men...</div>
</div>
<div class='dlg'>
	<div class='person_1'>Joe</div>
	<div class='spk_1'>And so on and so forth</div>
</div>
<div class='dlg'>
	<div class='person'>Jill</div>
	<div class='spk'>And whatever the weather</div>
</div>

 

Can anyone suggest a way of doing the conversion?

 

Thanks in advance.

ok, so lets presume you are outputting the dialogues from an array ( could be db, principle is the same):

$i = 0;
$messages = array(
    array('name'=> 'jack', 'message'=>'Lorem Ipsum'),
    array('name'=> 'jill', 'message'=>'Lorem Ipsum')
    array('name'=> 'jack', 'message'=>'Lorem Ipsum')
    array('name'=> 'jill', 'message'=>'Lorem Ipsum')
    array('name'=> 'jack', 'message'=>'Lorem Ipsum')
);
foreach($messages as $message)
{
if ($i % 2 != 0) # An odd row 
    $person = "person_1"; 
    $spk = "spk_1";
  else # An even row 
    $person = "person"; 
    $spk = "spk";
}
print '<div class="dlg">
           <div class="'.$person.'">'. $message['name'].'</div>
           <div class="'.$spk.'">'. $message['message'].'</div>
       </div>    
';
$i ++;
}
