Selenium XPath：祖先不包含

Question

在顶级“foo”的范围内找到具有类“bar”的div,其祖先没有类“foo”。例如,

<div class="foo">
    <div class="foo">
         <div><div>
         <div class="bar"> </div>
         </div></div>
    </div>

    <div class="bar"> </div>
</div>

WebElement root = driver.findElement(By.xpath("//div[@class='foo']"));
root.findElements(By.xpath(".//div[not(contains(@class, 'foo'))]//div[contains(@class, 'bar')]"));

root.findElements(By.cssSelector(":not(.foo) .bar"));

它只返回一个项：所需的
