Can't remove anchor tag from within p tag?

[rgbaman]

What is this feature about (expected vs actual behaviour)?

I don't know if I've misunderstood how to use this or whether this is a bug.

Any additional information?

I'm trying to parse this HTML to display only the content in the p tag, stripping the a tags out completely:

<section class="section" id="section-47" data-period="#period1">
   <div class="content">
      <p>The quick brown fox
         <a class="noteRef commentary F" href="#c563672">F1</a>
         jumps over 
         <a class="noteRef commentary F" href="#c563672">F1</a> 
         the lazy
         <a class="noteRef commentary F" href="#c1844523">F5</a>
         dog.
      </p>
   </div>
</section>

This is what I have tried so far with no luck and by following the examples and API docs:

$html = HtmlDomParser::file_get_html($url); // Gets full HTML - above is just a snippet.

foreach ($html->find('section .content p') as $section) {
   foreach($section->find('p a') as $a) {
      $a->outertext = '';
   }
   $content[] = $section->save;
}

My result is a blank. I have tried following the example but adding parenthesis to the save $content[] = $section->save(); throws an error:

BadMethodCallException
Method does not exist

I'm using Laravel.

Thank you for your help. Am I right in thinking you cannot use this on a remote URL without converting it to a string and storing it in a variable first?

[Lars Moelleken]

HtmlDomParser::file_get_html($url)

should also work

[rgbaman]

Thank you very much for your help, I've now got it working with file_get_html($url).

I'm not sure if you have a support forum as I had another question but I didn't want to jam up the issues log. Is there anywhere I can post it?

Yust use this issue tracker and write e.g. "Question:" in the subject.

Hint 💡: if you look for good examples, a good placec to look at, are always the test directory
