sorry i'm not RU. and not Eng.

PHP:

            $this->load->model('cofunction/tooltip');
                
            $tooltips = $this->model_cofunction_tooltip->getTooltip();
                
            if (isset($tooltips) && (strpos($this->data['description'], 'iframe') == false) && (strpos($this->data['description'], 'object') == false)){
                $xdescription = mb_convert_encoding(html_entity_decode($this->data['description'], ENT_COMPAT, "UTF-8"), 'HTML-ENTITIES', "UTF-8");                     
                libxml_use_internal_errors(true);
                $dom = new DOMDocument;             
                $dom->loadHTML('<div>'.$xdescription.'</div>');               
                libxml_use_internal_errors(false);
                
                $xpath = new DOMXPath($dom);                           
                foreach ($tooltips as $tooltip) {   
                    $common_link = $tooltip['common_link'];
                    $status = $tooltip['status'];
                    $target = $tooltip['target'];
                    $title = $tooltip['title'];
                    $link = mb_convert_encoding(html_entity_decode($tooltip['link'], ENT_COMPAT, "UTF-8"), 'HTML-ENTITIES', "UTF-8");                   
                    $description = html_entity_decode($tooltip['description'], ENT_QUOTES, 'UTF-8');
                                            
                    $pTexts = $xpath->query(
                        sprintf('///text()[contains(., "%s")]', $title)
                    );
                    
                    foreach ($pTexts as $pText) {
                        $this->parseText($pText, $title, $dom, $link, $common_link, $target, $description);
                    }

                                
                }
                        
                $this->data['description'] = $dom->saveXML($dom->documentElement);               
            }

PHP:

    private function parseText($node, $title, $dom, $link, $common_link, $target , $description) {               

       
        if (mb_strpos($node->nodeValue, $title) !== false) {
            $this->document->addScript('catalog/view/javascript/tooltip/jquery.cluetip.js');
            $this->document->addStyle('catalog/view/javascript/tooltip/jquery.cluetip.css');           
           
            $keywordOffset = mb_strpos($node->nodeValue, $title, 0, 'UTF-8');           
            $newNode = $node->splitText($keywordOffset);
            $newNode->deleteData(0, mb_strlen($title, 'UTF-8'));
           
            $span = $dom->createElement('a', $title);
            $span->setAttribute('target', $target);

            if ($link){
                $span->setAttribute('href', $link);
                $span->setAttribute('style', 'text-decoration:underline');
            } elseif ($common_link)  {
                $span->setAttribute('href', $common_link);
                $span->setAttribute('style', 'text-decoration:underline');
            } else {
                $span->setAttribute('style', 'text-decoration:none');
                $span->removeAttribute('target');
            }
           
            if ($description){
                $span->setAttribute('class', 'title tooltip-link');
                $span->setAttribute('title', $title.'|'.$description);
            }

            $node->parentNode->insertBefore($span, $newNode);
            $this->parseText($newNode ,$title, $dom, $link, $common_link, $target, $description);
        }                   
    }

Код:

let tracker = {}; // track href values

$('a').each(function(anc) {
  var href = $(this).attr('href');
  if (tracker.hasOwnProperty(href)) {
    $(this).replaceWith(`<div>${$(this).text()}</div>`);
  } else {
    tracker[href] = true;
  }
});
