simple html dom: how get a tag without certain attribute

I want to get the tags with "class" attribute equal to "someclass" but only those tags that hasn't defined the attribute "id".

I tried the following (based on this answer) but didn't work:

$html->find('.someclass[id!=*]');

Note:

I'm using Simple HTML DOM class and in the basic documentation that they give, I didn't find what I need.

Solution

  • Simple HTML DOM class does not support CSS3 pseudo classes which is required for negative attribute matching.

    It is simple to work around the limitation without much trouble.

    $nodes = array_filter($html->find('.something'), function($node){return empty($node->id);});
