find a specific div/class with preg_match_all

Hi all. I had this code and it works perfectly if i want to extract all the urls from a page.

<?php
$url = 'http://site.net';
$m= file_get_contents ($url);
preg_match_all ('/url="(.*?)"/',$m,$match );
print implode("<br>",$match[1]);
?>

PHP:

Now, i want to extract only a specific div or class from a page, like this:

<div id="links">
<li>...</li>
....
<li>...</li>
</div>

HTML:

I need the script to output just:

<li>...</li>
....
<li>...</li>

HTML:

I searched google how to do that but after 6 hours i decided to quit and ask here. Can anyone help me ? I don't know how to modify that 3rd row.

 

preg_match_all('#<div[^>]*>(.+?)</div>#is', $m, $match);

PHP:

 

Thanks danx10. This really works, but it output the content from the first div. I need to get the content from a specific div.

 

$specific_div = 'links';
preg_match_all('#<div\s*(?:id|class)\s*=\s*"'.preg_quote($specific_div).'">(.+?)</div>#is', $m, $match);

PHP:

 

Seriously, look into the PHP simple DOM library. I used to use regular expressions for stuff like that, it was crazy.

Thanks danx10. You're magic. I don't know how the f..k you did that because i don't understand nothing from that bracket.
Cheers!

P.S.: Can you make it to work even if the code is like this ?

P.P.S.: And could you do it to find something without considering the tag? I mean, if i want to find something but i don't know if it's a div, ul or ol, only the id name.

 

$specific_div = 'links';
preg_match_all('#<([a-z]+).+?(?:id|class)\s*=\s*("|\')'.preg_quote($specific_div).'\2[^>]*>(.+?)</\1>#is', $m, $match);

PHP:

Due to the changes within the expression, your $match array will change, theirfore you'd need to rectify $match[1] accordingly - what your after is the 3rd set of matches.

Also its untested.
