You can use DOMDocument to get at the attributes:

$html = '<li data-docid="thisisthevaluetoget" class="search-results-item"></li>';
$doc = new DOMDocument;
$doc->loadHTML($html);
$nodes = $doc->getElementsByTagName('li');
foreach ($nodes as $node) {
    if ($node->hasAttributes()) {
        foreach ($node->attributes as $a) {
            echo $a->nodeName.': '.$a->nodeValue.'<br/>';
        }
    }
}
