preg_replace

[nigeledge]

How would I use preg_replace in this situation?

I have an html file similar to this:

<div class="body">
<a href="somelink.html">Some Link</a><br>
This is some text<br>
</div>

<br>

<div class="body">
<a href="anotherlink.html">Another Link</a><br>
Here is some more text.<br>
</div>

I want to extract the links so I end up with this....

<a href="somelink.html">Some Link</a><br>
<a href="anotherlink.html">Another Link</a><br>

I cannot figure out what pattern I should be searching for. Any help would be greatly appreciated.

smth like

pre_replace('#<div.?(<a.?</a><br>).*?/div>#i', '\1', $text);

afaik .? must give us the shortest possible match, thus
<div.?<a matches with the first A tag after the opening <div>.

Maybe here are some minor errors...

Thanks. Where can I find a good dictionary of all the expressions for preg?

they are covered OK in the manual.
And you may also use any Perl regexp documentation, since preg_* (aka PCRE) are (almost) Perl-Compatible-Reg-Exps.
