How to cut an entire block of html using php?

Question

PHP

Good afternoon!
I get the html code of a specific page. Inside there is this structure:

<div class="container">
  <div class="box">
    ..... (some code)
  </div>
  <div class="box">
    ..... (some code)
  </div>
  <div class="box">
    ..... (some code)
  </div>
  <div class="box">
    ..... (some code)
  </div>
</div>

How can I cut out the entire container block with all the content? Regular expressions come to mind, but I have no idea how to cut like this if our block ends with </div>, but before that, there is also </div>.
Thank you in advance!

$content = '<div class="container">
  <div class="box">
    ..... (some code)
  </div>
  <div class="box">
    ..... (some code)
  </div>
  <div class="box">
    ..... (some code)
  </div>
  <div class="box">
    ..... (some code)
  </div>
</div>';

preg_match("#<div class=\"container\">(.+?)\n<\/div>#is", $content, $res);

var_dump($res);

and don't say it's junk ;) For those who have worked with JQuery selectors, it's easier or not
