I am working on some blog layout and I need to create an abstract of each post (say 15 of the lastest) to show on the homepage. Now the content I use is already formatted in html tags by the textile library. Now if I use substr to get 1st 500 chars of the post, the main problem that I face is how to close the unclosed tags.
e.g
<div>.......................</div>
<div>...........
<p>............</p>
<p>...........| 500 chars
</p>
<div>
What I get is two unclosed tags <p> and <div> , p wont create much trouble , but div just messes with the whole page layout. So any suggestion how to track the opening tags and close them manually or something?

What Is a Void Element? The void elements or singleton tags in HTML don't require a closing tag to be valid. These elements are usually ones that either stand alone on the page or where the end of their contents is obvious from the context of the page itself.
XHTML is more strict than HTML, and requires that all open tags must be closed, even if they're not container tags. Therefore, non-container tags end in />. For example, the tag for a line break is <br />.
All major browsers have an option that enables you to see the page's source code when you right-click. Click “View Page Source” in Firefox and Chrome, for example. Search for additional meta tags on the page and note the attributes and values that appear next to those.
If you don't add a closing tag the browser won't know where it ends. It will take the next tag and think it belongs to the previous tag without the closing tag.
There are lots of methods that can be used:

As ajreal said, DOMDocument is a solution.
Example :
$str = "
<html>
<head>
<title>test</title>
</head>
<body>
<p>error</i>
</body>
</html>
";
$doc = new DOMDocument();
@$doc->loadHTML($str);
echo $doc->saveHTML();
Advantage : natively included in PHP, contrary to PHP Tidy.
