Is it possible to extract Dom Elements from htmlentities() function in php? - php

Question

I appreciate the time you take to try and help me with my question.
So what i am doing is trying an html parser from a link. So I use curl first to link to the website then I convert it into htmlentities() so it doesn't load on the page so I get a string from that then i use the DOM object to extract the tag from. I checked different methods for a parser on google search so i learned a little bit about it then i execute my script but the problem is that the string is getting saved as textCont and not as a real html document so i would like to know how can convert htmlentities string into a real dom document and extract elements from it ?
the image of the var_dump is here
here is my script:
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'https://www.usatoday.com/story/news/world/2021/02/17/dubai-princess-sheikha-latifa-says-she-hostage-after-flee-attempt/6778014002/?utm_source=feedblitz&utm_medium=FeedBlitzRss&utm_campaign=usatodaycomworld-topstories');
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($curl);
curl_close($curl);
$htmlentities = htmlentities($result);
// I added the code here
$htmlDom = new DOMDocument();
$htmlDom->loadHTML($htmlentities);
$htmlDom->preserveWhiteSpace = false;
$styles = $htmlDom->getElementsByTagName('style');
foreach ($styles as $style) {
$item = $style->getElementsByTagName('td');
//echo the values
echo '1: '.$item->item(0)->nodeValue.'<br />';
echo '2: '.$item->item(1)->nodeValue.'<br />';
echo '3: '.$item->item(2)->nodeValue;
}
EDIT:
what i added next to the code is this:
$htmlentities = htmlentities($result);
$htmlentities = str_replace(""",'"', $htmlentities);
$htmlentities = str_replace("'","'", $htmlentities);
$htmlentities = str_replace("<","<", $htmlentities);
$htmlentities = str_replace(">",">", $htmlentities);
libxml_use_internal_errors(true);
$htmlDom = new DOMDocument();
$htmlDom->loadHTML($htmlentities);
libxml_clear_errors();
var_dump($htmlDom);
