XPath : All divs which not have a specific child

I'm have HTML file and I'm parsing it with XPath. I'm want to select all [div] nodes which not have [p] tag(s) in it.

For example, input:

<div>
    <p>no1</p>
</div>
<div>
    <div>
        <p>no2</p>
    </div>
</div>
<div>
    yes!!!
</div>

Expected output:

yes!!!

I'm tried this XPath query, which not working for me:

//div[not (p)]
