DOMNode::isEqualNode() is incorrect when attribute order is different #13012
Description
Description
The spec says: "If A is an element, each attribute in its attribute list has an attribute that equals an attribute in B’s attribute list." The order in which the attributes are listed should not matter.
I double checked the expected behaviour in Gecko/Blink just in case.
<?php
$dom = new DOMDocument;
// <x a="a" b="b"/>
$el1 = $dom->createElement('x');
$el1->setAttribute('a', 'a');
$el1->setAttribute('b', 'b');
// <x b="b" a="a"/>
$el2 = $dom->createElement('x');
$el2->setAttribute('b', 'b');
$el2->setAttribute('a', 'a');
var_dump($el1->isEqualNode($el2));Resulted in this output:
bool(false)
But I expected this output instead:
bool(true)
