If you need to grap the categories names:

// Suppress invalid markup warnings
libxml_use_internal_errors(true);

// Create SimpleXML object
$doc = new DOMDocument();
$doc->strictErrorChecking = false;
$doc->loadHTML($html); // $html - string fetched by CURL 
$xml = simplexml_import_dom($doc);

// Find a category nodes
$categories = $xml->xpath("//span[@class='refinementLink']");

EDIT. Using DOMDocument

$doc = new DOMDocument();
$doc->strictErrorChecking = false;
$doc->loadHTML($html);

$xpath = new DOMXPath($doc);

// Select the parent node
$categories = $xpath->query("//span[@class='refinementLink']/..");

foreach ($categories as $category) {
    echo '
';
    echo $category->childNodes->item(1)->firstChild->nodeValue; 
    echo $category->childNodes->item(2)->firstChild->nodeValue;
    echo '
';
