Looks like you need to read up on the modifiers for preg_* functions.  Start
here:  http://us3.php.net/manual/en/reference.pcre.pattern.modifiers.php

I would change your "second line" regex to the following.

$content = preg_replace("/<p.*>/is", "<p>", $content);

The modifiers after the second / are

i = case-insensitive
s = include new lines in your '.' character match.
    New lines are excluded by default.

Can't remember right now, nor do I have the time to test, you might need to
invert the greediness of the match using a 'U' after the second / also.


$content = preg_replace("/<p.*>/isU", "<p>", $content);


Let us know how this works out for you.

PS: you might want to swap the order of these two statements.
