In the second example you're trying to match <p></p> directly, with an additional assertion.
Try /<p>(?=.*?\[tab\]).*?<\/p>/ instead. But that doesn't check if the [tab] occurs before the </p>, so don'T try to mess with lookarounds but use your first pattern.
Update: OK, that doesn't fix your real problem. I'll have to think a bit more about it. In this simple case you can just use [^<>] instead of a dot everywhere between <p> and </p>.
The old truth that HTML shouldn't be parsed with regexes still holds.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
