It depends on the data -- if the data is incorrectly formatted (a missing ' for instance), they may not do the same thing. And '.+?' has the tendency to be slower than '[^']+'. Usually, the more restrictive a pattern is, the faster: there's less opportunity to backtrack. There's much more commitment in '[^']+' then there is in '.+?': the former will always match two quotes in succession, and whatever is in between, regardless how the rest of the pattern looks like, but that's not the case with '.+?'; there's nothing stopping the .+? part to match quotes.

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).
