try this

$crawler->filter('.position')->getNode(0)->setAttribute('ATTR','VALUE');

this code get the first node matches the selector and change the value of the selected attribute.

Nope. This one doesn't work for me when I am trying to loop nodes and update needed values – Roman Kozin Sep 07 '21 at 21:39

As per documentation:

All filter methods return a new Crawler instance with filtered content.

hence

$populatedCrawler = $crawler->filter("table.positions")->addHtmlContent("<tr class="position"></td></td></tr>");

echo '<pre>'.$populatedCrawler->filter('.position')->html().'</pre>';

will give you what you expect.
