Code:

$dom = new DOMDocument;
$dom->loadHTML($entity->body[$field_lang][0]['value']);
foreach ($dom->getElementsByTagName('a') as $node) {
  $node->removeAttribute('href');
}
$entity->body[$field_lang][0]['value'] = $dom->saveHTML();

it's giving me output like:

<a>link1</a> etc...

I how do i get rid of tags and output only text Ex. link1

Answer 1

$text = strip_tags($link);

Refer to this: http://php.net/manual/en/function.strip-tags.php

Answer 2

To replace specific href using DOMDocument

$xml = new DOMDocument();
$xml->loadHTML($entity->body[$field_lang][0]['value']);

$links = $xml->getElementsByTagName('a');

//Loop through each <a> tags and replace them by their text content
for ($i = $links->length - 1; $i >= 0; $i--) {
  $linkNode = $links->item($i);
  $lnkText = $linkNode->textContent;

  if ($url == $linkNode->attributes->item(0)->nodeValue) {
    $newTxtNode = $xml->createTextNode($lnkText);
    $linkNode->parentNode->replaceChild($newTxtNode, $linkNode);
  }
}
$entity->body[$field_lang][0]['value'] = $xml->saveHTML();
