Adding New Lines to WordPress Post

First off I have gone through this link http://codex.wordpress.org/Integrating_WordPress_with_Your_Website. I cannot use this.

I am trying to get the latest post from a WordPress installation on a remote server I own. They share the same database server so that is where I am taking the post now and then brining it back into my PHP app. This all works.

What doesn't work is the display. Before I was using nl2br to make new lines but this does not work right.

I have noticed that WordPress does some post-processing to add p tags to certain lines they consider should be paragraphs (not in uls or lis for example). They do this after grabbing the post from the DB (the p tags are not saved to DB).

I have tried to find out what post-processing they use in the source code but I have come up blank after finding the the_content function etc and where the $post var comes from but not finding the code I am looking for.

What post-processing function does WordPress use to add these paragraphs to make their posts look ok?

Edit

For regex or general PHP people here I am looking to change something like:

<em><a href="link">awesome link</a></em>
<h3>Awesome Head</h3>
lalalaalal
<ul>
<li>Awesome li</li>
</ul>

Into something like:

<p>
    <em><a href="link">awesome link</a></em>
</p>
<h3>Awesome Head</h3>
<p>lalalaalal</p>
<ul>
<li>Awesome li</li>
</ul>

Missing out tags that obviously should not have p tags around them like h and ul and li tags.

The right thing to do would be as @BryanH said: use the RSS feed which already has the post pre-formatted for you.

However if you don't want to make an XML parser and deal with all the stuff that comes with it just to get a blog post then you can use something like:

$content = preg_split('/\\r?\\n/', str_replace(']]>', ']]&gt;', $post->content));

foreach($content as $line){
    if(strlen(trim($line)) > 0){
        $line = trim($line);
        if(!preg_match('/^(<|<\/)(ul|li|div|h[1-6])/', $line)){
            echo '<p>'.$line.'</p>';
        }else{
            echo $line;
        }
    }
}

This is the code I personally used to solve this problem in the end.

There is probably a more robust and elegant way of doing this (quickly coded) however I tested this on a very complex blog post with images and lots of different tags and it seemed to work nicely without any errors.

I am still unsure what WP uses but this solves my problem in the end.

The easiest, fastest way: parse the latest post from the RSS feed. You'll find all of the <p> tags automatically added for you.
