[英]Selenium XPath: ancestor does not contain
Find the div with class "bar" whose ancestor does not have class "foo" within the scope of top-level "foo".查找具有类“bar”的 div,其祖先在顶级“foo”范围内没有类“foo”。 For example,例如,
<div class="foo">
<div class="foo">
<div><div>
<div class="bar"> </div>
</div></div>
</div>
<div class="bar"> </div>
</div>
Find the bar not inside the nested "foo".找到不在嵌套“foo”内的栏。
And the XPath I tried is:我尝试的 XPath 是:
WebElement root = driver.findElement(By.xpath("//div[@class='foo']"));
root.findElements(By.xpath(".//div[not(contains(@class, 'foo'))]//div[contains(@class, 'bar')]"));
But the XPath returns two elements.但是 XPath 返回两个元素。 Also tried css selector:还试过 css 选择器:
root.findElements(By.cssSelector(":not(.foo) .bar"));
Not working either.也不工作。
Try this XPath-1.0 expression:试试这个 XPath-1.0 表达式:
//div[contains(@class, 'bar') and not(ancestor::*[@class='foo'])]
It only returns one item: the desired <div class="bar"> </div>
.它只返回一项:所需的<div class="bar"> </div>
。
这个只返回第二个栏(至少当我运行它时......)
//*[@class='bar'][(parent::div[@class='foo'])]
如果您尝试使用 bar 类访问直接子 div,那么这里是 xpath。
//div[@class='bar' and parent::div[@class='foo']]
