帮助 xpath 邻居

大家好，我有这样的站点布局，我想通过 XPATH 访问带有 @class product-grid 的元素，但同时考虑到如果邻居有 category-grid 类我将无法到达那里的条件换句话说，如果不是类别网格邻居，则转到产品网格

<div class="page-body">
    <div class="category-grid"><span>Есть категория</span></div>
    <div class="product-selectors"></div>
    <div class="product-filters"></div>
    <div class="product-grid">
        <div>..Не должен найти..</div>
    </div>
</div>

//div[1][@class='product-selectors' or contains(@class,'slider-wrapper') or contains(@class,'category-description')]/parent::div/div[contains( @class,'product-grid')]

我使用了这个设计并且它有效，但是，这些元素并不总是放在首位

<div class="page-body">
    <div class="slider-wrapper"><span></span></div>
    <div class="product-selectors"></div>
    <div class="product-filters"></div>
    <div class="product-grid">
        <div>..Должен найти..</div>
    </div>
</div>
<div class="page-body">
    <div class="slider-wrapper"><span></span></div>
    <div class="category-grid"><span>Есть категория</span></div>
    <div class="product-filters"></div>
    <div class="product-grid">
        <div>..Не Должен найти..</div>
    </div>
</div>
