Answer 1

I managed to get what I need with this code (based on Khue Vu's code) :

$d = new DOMDocument();
$d->loadHTML($ads); // the variable $ads contains the HTML code above
$xpath = new DOMXPath($d);
$ls_ads = $xpath->query('//a');

foreach ($ls_ads as $ad) {
    // get ad url
    $ad_url = $ad->getAttribute('href');

    // set current ad object as new DOMDocument object so we can parse it
    $ad_Doc = new DOMDocument();
    $cloned = $ad->cloneNode(TRUE);
    $ad_Doc->appendChild($ad_Doc->importNode($cloned, True));
    $xpath = new DOMXPath($ad_Doc);

    // get ad title
    $ad_title_tag = $xpath->query("//div[@class='title']");
    $ad_title = trim($ad_title_tag->item(0)->nodeValue);

    // get ad image
    $ad_image_tag = $xpath->query("//img/@src");
    $ad_image = $ad_image_tag->item(0)->nodeValue;
}
