    I used this sintax It's takes less time to load and also it's grabs all the contents and places it nicely. with import of css I was able to get all I wanted. Now I can go ahead and make additable css styles and also other setups.

    Plan is to get this to working WP/JOMLA plugin.

        <?php
$merchantID = '3553552';
$finn_link = 'https://www.finn.no/car/used/search.html?orgId=' . $merchantID;
$finnTagName = 'article';
$finnAttrName = 'class';
$finnAttrValue = 'ads__unit';

$finnDom = new DOMDocument;
$finnDom->preserveWhiteSpace = false;
@$finnDom->loadHTMLFile($finn_link);

$finnHtml = getTags( $finnDom, $finnTagName, $finnAttrName, $finnAttrValue );

function getTags( $finnDom, $finnTagName, $finnAttrName, $finnAttrValue ){
    $finnHtml = '';
    $domxpath = new DOMXPath($finnDom);
    $newDom = new DOMDocument;
    $newDom->formatOutput = true;

    $filtered = $domxpath->query("//$finnTagName" . '[@' . $finnAttrName . "='$finnAttrValue']");
    // $filtered =  $domxpath->query('//div[@class="className"]');
    // '//' when you don't know 'absolute' path

    // since above returns DomNodeList Object
    // I use following routine to convert it to string(html); copied it from someone's post in this site. Thank you.
    $i = 0;
    while( $myItem = $filtered->item($i++) ){
        $node = $newDom->importNode( $myItem, true );    // import node
        $newDom->appendChild($node);                    // append node
    }
    $finnHtml = $newDom->saveHTML();
    return $finnHtml;
}

?>
<?php echo $finnHtml; ?>

    Class DOMDocument does not contains method getElementsByClassName

    to get the text and image,

    <?php
$url="https://www.finn.no/car/used/search.html?orgId=3553552&sort=PUBLISHED_DESC";
$html=file_get_contents($url);
$doc = new DOMDocument();
libxml_use_internal_errors(true); // use it if getting error DOMDocument::loadHTML(): Tag finn-topbar invalid in Entity
$doc->loadHTML($html);

$arts = $doc->getElementsByTagName('article'); // get tag article
$display = "";
foreach($arts as $index => $art){
    $imgs = $doc->getElementsByTagName('img'); // get tag img in tag article
    $article = $art->textContent; // text of article
    $display.= $article."</br>";
    $display.= $imgs[$index]->getAttribute('src')."</br>"; // src img in tag img
}
?>

<div><?php echo $display; ?></div>

    try use regex preg_match_all,

    <?php
    $str = file_get_contents('https://www.finn.no/car/used/search.html?orgId=3553552&sort=PUBLISHED_DESC');
    preg_match_all('#<article class="ads__unit (.*)">(.*?)</article>#', $str, $matches);
    $div = "";
    foreach($matches as $match){
        foreach($match as $mt){
            $div .= $mt;
        }
    }
?>
<div><?php echo $div ?></div>

    or

    <?php
    $str = file_get_contents('https://www.finn.no/car/used/search.html?orgId=3553552&sort=PUBLISHED_DESC');
    
    $div = "";
    if(preg_match('#<div class="ads (.*)">(.*)</div>#', $str, $m)){
        $div .= $m[0];
    } else {
        echo 'Regex syntax has to be improved to your search criteria'.PHP_EOL;
    }
?>

<div><?php echo $div; ?></div>
