Get html nodes that are not within a node with attribute X

I have the following xpath query, and I am not sure how to make it so it only finds items with the attribute pi-repeat, but not it's children that have that attribute.

$xpath = new DOMXPath($dom);
foreach ($xpath->query('//*[@pi-repeat]') as $node) {
    // Do stuff
}

Html example:

<body>
    <div pi-repeat="thing1">
        <div pi-repeat="sub-item"></div>
    </div>
    <div class="a-class">
        <div pi-repeat="thing2">
            <div pi-repeat="sub-item"></div>
        </div>
    </div>
</body>

As you can see here there are four pi-repeat attributes, I would like my query to only select the ones that are not within an element pi-repeat attribute.

In this case, only thing1 and thing2 would get selected.

The 2nd predicate in the XPath below will do the job. It filters out elements where ancestor element has pi-repeat attribute :

//*[@pi-repeat][not(ancestor::*[@pi-repeat])]
