How will you otherwise handle hard-to-find-programmatically errors such as <p>What a mighty fine and warm <a href="htt or <p>His name was &quot;Emil&qu?

Solution 2:

Have you taken a look at Tidy?

Example:

$options = array("show-body-only" => true); 
$tidy = tidy_parse_string("<B>Hello</I> How are <U> you?</B>", $options);

Solution 3:

I would install the PHP bindings for Tidy. You can then use this to clean up an HTML fragment using the following code:

<?php$fragment = '<p>What a mighty fine <a href="blah">da';

$tidy = new tidy();

$tidy->parseString($fragment,array('show-body-only'=>true),'utf8');
$tidy->cleanRepair();

echo$tidy;
