PHP Simple HTML DOM - method find retrieve empty array - php

Question

Now I am trying to write a PhP parser and I don't why my code return an empty array. I am using PHP Simple HTML DOM. I know my code is't perfect, but it's only for testing.
I will be appreciate for any help
public function getData() {
// get url form urls.txt
foreach ($this->list_url as $i => $url) {
// create a DOM object from a HTML file
$this->html = file_get_html($url);
// find array all elements with class="name" because every products having name
$products = $this->html->find(".name");
foreach ($products as $number => $product) {
// get value attr a=href product
$href = $this->html->find("div.name a", $number)->attr['href'];
// create a DOM object form a HTML file
$html = file_get_html($href);
if($html && is_object($html) && isset($html->nodes)){
echo "TRUE - all goodly";
} else{
echo "FALSE - all badly";
}
// get all elements class="description"
// $nodes is empty WHY? Tough web-page having content and div.description?
$nodes = $html->find('.description');
if (count($nodes) > 0) {
$needle = "Производитель:";
foreach ($nodes as $short_description) {
if (stripos($short_description->plaintext, $needle) !== FALSE) {
echo "TRUE";
$this->data[] = $short_description->plaintext;
} else {
echo "FALSE";
}
}
} else {
$this->data[] = '';
}
$html->clear();
unset($html);
}
$this->html->clear();
unset($html);
}
return $this->data;
}

hi you should inspect the element and copy->copy selector and use it in find method to getting the object
