How is it not a PHP problem? The OP is asking about using regex in PHP.
Anyway, @OP: You might be able to get what you're after with one
regex. Check out the print_r output to figure out what you need, and
if it works:
$data = '<div>Foo bar <p><em>baz</em></p> Ishmael</div>';
// use a different delimiter when / occurs, to avoid
// unnecessary escaping
$re = '%<([\w.:-]+)[^<>]*>(.*?<p[^<>]*>(.*?)</p>.*?)</\1>%i';
preg_match_all($re, $data, $matches);
print_r($matches);
