Remove a HTML tag class DOM

[zeus69]

HI,

I have this code that deletes any div that contains class = "comments-box"

$dom = new DOMDocument;
$dom->loadHTML($html, LIBXML_HTML_NODEFDTD | LIBXML_HTML_NOIMPLIED);
$xp = new DOMXPath($dom);

// get the node list of div nodes with "target" class
$spanNodeList = $xp->query('//div[contains(@class, "comments-box")]');

foreach ($spanNodeList as $spanNode) {
$spanNode->parentNode->replaceChild($spanNode->firstChild, $spanNode);
}

I need it to delete all the divs that it also contains
class = "heycomments-box"
class = "sdfcomments-box"
class = "comments-boxsdfdfh"

class = "sdgsdgcomments-boxsdfdfh"

Regards

Okay. Are you saying that code doesn't do it? Because it looks like it would do it.

PS: If you want to remove a node, remove the node.

I need what it does, for all class that contains "comments-box"

In regex, I do this, (. *?)comments-box(. *?). I don't know how to do with DOM

You could take the code in your first post, make it a function and use the " wash, rinse, repeat" approach.

This time, your answer doesn't help me with anything, sorry

I need that if a div contains a class that includes word "comments-box". example: "23comments-box234"; "sdgcomments-boxsdg" and feels others, is eliminated with DOM code that I wrote above

 

Sorry and Thanks for your time lost with me

You want to do something. Your code already does it. What is the problem?

[zeus69]

I need something like this with Dom

preg_replace('#<div class="(.*?)comments-box(.*?)">(.*?)</div>#', '', $html);  

 

 

Must delete all div, which contains class combinations that contains word comments-box. They can be billions. I can't do it manually

YOUR CODE WORKS FINE. WHAT IS THE PROBLEM?

[zeus69]

now I understand, it was my mistake
It must delete everything HTML inside the div that includes class comments-box (not just div)

Okay. Then see the link in my first reply.

What @requinix said

foreach ($spanNodeList as $spanNode) {
    $spanNode->parentNode->removeChild($spanNode);
}
