<?php
$str = 'Categorieën
<a href="/categorie/337487">Aangemelde sportwagens</a> 
<a href="/categorie/337679">Daniel den Hoed kliniek</a> 
<a href="/categorie/338998">Deelnemers over hun auto.</a>

<a href="/categorie/340270">Passagiers over de MM</a> 
<a href="/categorie/337484">SPONSOR OF DONEER!</a> 
</div>';

preg_match('/Categorieën<\/span>(.*?)<\/div>/', $str, $matches);
$answer = htmlentities($matches[1]);
print $answer;
?>

A few questions:
1) Will that span always have the same name: Categorieën? If not I can edit that part out a little.
2) I displayed the actual html text (not the links) at the end using htmlentities. If you actually wanted those links to appear, just remove the htmlentities(), but leave $answer = $matches[1];

Not tested but it looks good to me. Just get the information into $str then run that preg_match(). Enjoy,

BogoJoker

sure, but it would be this:
$str = file_get_contents('http://www.whatevermyurlis.com');

$str = file_get_contents('http://www.whatevermyurlis.com');

ok

<?php
$str = file_get_contents('http://maartenmemorial.web-log.nl');

preg_match('/Categorieën<\/span>(.*?)<\/div>/', $str, $matches);
$answer = htmlentities($matches[1]);
print $answer;
?>

gives me a blank page.

The period will "match any character except newline (by default)". You can alter that behavior with the "s" modifier:

"If this modifier is set, a dot metacharacter in the pattern matches all characters, including newlines. Without it, newlines are excluded. This modifier is equivalent to Perl's /s modifier. A negative class such as [^a] always matches a newline character, independent of the setting of this modifier."

i.e., preg_match('/pattern/s' ...);

Or:

preg_match('/Categorieën<\/span>(.*?)<\/div>/s', $str, $matches);

Also note that the links wont work, because they are relative to the server you got them from!
Here is a fix:
<?php
$str = file_get_contents('http://maartenmemorial.web-log.nl');
$str = str_replace("\n", "", $str);
$str = str_replace("\r", "", $str);
preg_match('/Categorieën<\/span>(.*?)<\/div>/', $str, $matches);
$answer = $matches[1];
$answer = preg_replace('/href="(.*?)"/', 'href="http://maartenmemorial.web-log.nl' . "\$2\"", $answer);
print $answer;
?>

You should probably ask the site for permission to do this as well.
