Question

Now found query if '$NotXP->query' = query return string?!
How to make work next code?

$list = $xp->query('//table[#class="table-list quality series"] tbody');
$link = $list->query('//tr[#class="item"]');
$arr_links = [];
foreach ($link as $link_in_cycle) {
$link_quality = $link_in_cycle->query('//td[#class="column first video"]');
$link_audio = $link_in_cycle->query('//td[#class="column audio"]');
$link_size = $link_in_cycle->query('//td[#class="column size"]');
$link_seed = $link_in_cycle->query('//td[#class="column seed-leech"] span[#class="seed"]');
$link_download_url = $link_in_cycle->query('//td[#class="column last download"] a')->getAttribute("data-default");

I've made a few changes to help me in debug the code. The main thing is that your XPath expressions were invalid, you can always try a site like FreeFormatter which allows you to check your expressions with some example source.
$doc = new \DOMDocument();
$doc->loadHTMLFile($url);
$xp = new \DOMXPath($doc);
$list = $xp->query('//table[#class="table-list quality series"]//tr[#class="item"]');
$arr_links = [];
foreach ($list as $link_in_cycle) {
$link_quality = $xp->query('//td[#class="column first video"]/text()', $link_in_cycle)[0]->wholeText;
$link_audio = $xp->query('//td[#class="column audio"]/text()', $link_in_cycle)[0]->wholeText;
$link_size = $xp->query('//td[#class="column size"]/text()', $link_in_cycle)[0]->wholeText;
$link_seed = $xp->query('//td[#class="column seed-leech"]//span[#class="seed"]/text()', $link_in_cycle)[0]->wholeText;
$link_download_url = $xp->query('//td[#class="column last download"]//a/#data-default', $link_in_cycle)[0]->value;
echo $link_quality.PHP_EOL;
echo $link_audio.PHP_EOL;
echo $link_size.PHP_EOL;
echo $link_seed.PHP_EOL;
echo $link_download_url.PHP_EOL;
}
The XPath expressions try and retrieve the text node in each element, which will return a list of all of the nodes, this code does assume there isn't any whitespace around the actual content (and uses [0] to fetch the first element of the list). The wholetext is just the actual content of the DOMText element.
With the sample content you gave (plus the surrounding bits I had to invent) it gives...
720x400
mp3
5.70 Gb
15
