Question

Answer 1

+1 A:

Instead of doing the second query try textContent

foreach ($arts as $art) {
    echo $art->textContent;
}

textContent returns the text content of this node and its descendants.

As an alternative, change the XPath to

$expression="//div[@class='thebest']/span[@class='title' or @class='desc']";
$arts = $xpath->query($expression);

foreach ($arts as $art) {
    echo $art->nodeValue;
}

That would fetch the span children of the divs with a class thebest having a class of title or desc.

Answer 2

+1 A:

Make the queries relative... start them with a dot (e.g. ".//…").

foreach ($arts as $art) {
    // Note: single slash (direct child)
    $titles = $xpath->query("./span[@class='title']", $art);
    if ($titles->length > 0) {
        $title = $titles->item(0)->nodeValue;
        echo $title;
    }

    $descs = $xpath->query("./span[@class='desc']", $art);
    if ($descs->length > 0) {
        $desc = $descs->item(0)->nodeValue;
        echo $desc;
    }
}
