NO REGEX HTML! REGEX HTML BAD! [MONGO SMASH](http://www.youtube.com/watch?v=28khv-BydeY)! — cwallenpoole, Sep 23 '11 at 23:07
That is HTML, not ASP. The HTML might be generated by ASP, but you never see the ASP so thinking about it is just a distraction. — Quentin, Sep 23 '11 at 23:20

I guess I should start with the typical "Don't parse HTML with regex". This would be easy with XPath (using DOMXpath):

$dom = new DOMDocument();
@$dom->loadHTML($page);
$dom_xpath = new DOMXPath($dom);
$entries = $dom_xpath->evaluate("//a");
foreach ($entries as $entry) {
    print $entry->nodeValue;
}

But if you must go the regex route, I imagine the greedy star .* is the source of your problems. Try this:

preg_match_all("@<a[^>]+>(.+?)</a>@/", $page, $matches, PREG_SET_ORDER);

Ah, whatever...

$page = file_get_contents('http://www.codacons.it/rassegna_quest.asp?idSez=14');
preg_match_all('#<a href="articolo(.*?)" title="Dettaglio notizia">(.*?)</a>#is', $page, $matches);

$count = count($matches[1]);
for($i = 0; $i < $count; $i++){
    echo '<a href="articolo'.$matches[1][$i].'">'.trim(strip_tags(preg_replace('#(\s){2,}#is', '', $matches[2][$i]))).'</a>'; 
}

Result:

<a href="articolo.asp?idInfo=138400&amp;id=">'Questionario':OFFICINE PER L'ASSISTENZA E MANUTENZIONI VEICOLI</a>
<a href="articolo.asp?idInfo=138437&amp;id=">'Questionario':RIVENDITORE AUTO USATE</a>
<a href="articolo.asp?idInfo=127900&amp;id=">'Questionario':RACCOLTA RICICLATA DEI RIFIUTI DI IMBALLAGGI IN PLASTICA</a>
<a href="articolo.asp?idInfo=138861&amp;id=">'Questionario':DONNE E POLITICA</a>
