Description
Consider the following HTML:
<fieldset id="outer" disabled="disabled">
<fieldset id="target1"></fieldset>
<legend>
<fieldset id="target2"></fieldset>
</legend>
<legend>
<fieldset id="target3"></fieldset>
</legend>
</fieldset>When I query :disabled I expect to see three elements returned (all fieldsets except target2):
- outer
- target1
- target3
Here's the relevant section from the HTML spec:
https://html.spec.whatwg.org/multipage/form-elements.html#concept-fieldset-disabled
The relevant condition for disabled is:
It is a descendant of another fieldset element whose disabled attribute is specified, and is not a descendant of that fieldset element's first legend element child, if any.
Reproducer below.
This was discovered because of a report of a divergation between Symfony's CssSelector and PHP 8.4's native CSS support. I.e. the following PHP 8.4 code produces the right result:
$dom = Dom\HTMLDocument::createFromString(<<<HTML
<html xmlns="http://www.w3.org/1999/xhtml">
<fieldset id="outer" disabled="disabled">
<fieldset id="target1"></fieldset>
<legend>
<fieldset id="target2"></fieldset>
</legend>
<legend>
<fieldset id="target3"></fieldset>
</legend>
</fieldset>
</html>
HTML);
foreach ($dom->querySelectorAll(':disabled') as $node) {
var_dump($node->id);
}How to reproduce
<?php
require __DIR__.'/vendor/autoload.php';
use Symfony\Component\CssSelector\CssSelectorConverter;
$converter = new CssSelectorConverter();
$xpath = $converter->toXPath(":disabled");
echo $xpath, "\n";
$dom = new DOMDocument;
$dom->loadHTML(<<<HTML
<html xmlns="http://www.w3.org/1999/xhtml">
<fieldset id="outer" disabled="disabled">
<fieldset id="target1"></fieldset>
<legend>
<fieldset id="target2"></fieldset>
</legend>
<legend>
<fieldset id="target3"></fieldset>
</legend>
</fieldset>
</html>
HTML);
$xp = new DOMXPath($dom);
foreach ($xp->query($xpath) as $node) {
var_dump($node->id);
