php xpath replacement doesn't carry certain value

Question

Here is my code:

       $xpath_query = $xpath->query('//div[@class="paragraph-content"]//h2[1]');
       $i = 0;
       foreach($xpath_query as $header){ 
          if (!empty($header->nodeValue) && $i == 0){
            $replacement  = $dom->createDocumentFragment();
            $replacement  ->appendXML("<h1>$header->nodeValue</h1>");
            $header->parentNode->replaceChild($replacement  , $header);
          }  
          $i++;
       }

I'm grabbing the <h2> tag in the xpath and replacing it with <h1>

Where there is a value like this "Dialed in to hike & trail" in the <h2> tag and its being replaced to <h1> tag it doesn't show the text.

the "&" or &amp is causing the replacement to break, the $header->nodeValue

how can I escape $header->nodeValue, meaning if there are cases in the string where I have a <br> tag or &amp. When I have a <br> tag or have & in the text, it breaks the replacement.

You may need to ensure that the entities are encoded when you create the HTML (I've used htmlentities())...

$replacement  ->appendXML("<h1>".htmlentities($header->nodeValue)."</h1>");

I have resolved the issue by using this :

$replacement  ->appendXML("<h1>".htmlspecialchars($header->nodeValue)."</h1>");
