Selenium WebDriver FindElements(By.XPath()) 不返回任何数据

Question

我正在尝试引用下面 HTML 中的链接元素。

我尝试引用的元素是其中包含“WANT_TO_FIND_THIS_LINK”的元素。

使用它可以找到主 div 就好了：

var productHolder = driver.FindElements(By.XPath("//div[@data-partnumber='123456']"));

但是当我尝试访问该链接时，它什么也没返回。 我尝试了多种不同的方法，但它们都没有返回任何结果：

var productHolder = driver.FindElements(By.XPath("//div[@data-partnumber='123456']//div[@class='fc-image image-fit']//a"));
var productHolder = driver.FindElements(By.XPath("//div[@data-partnumber='123456']//div[contains(@class, 'fc-image')]"));
var productHolder = driver.FindElements(By.XPath("//div[@data-partnumber='123456']//div[@class='fc-image image-fit']//a"));

但是当我回到顶部时：

var productHolder = driver.FindElements(By.XPath("//div[@data-partnumber='123456']"));

效果很好。

在这里尝试一切：http://xpather.com/它找到了我需要的东西。我做错了什么，任何帮助都会很棒！

Answer 1

给定提供的 HTML，此 CSS 选择器将找到 A 标签。

div[data-partnumber='123456'] div.fc-image a

如果您必须有一个 XPath，则相当于上面的内容是

//div[@data-partnumber='123456']//div[contains(@class,'fc-image')]/a

---

注意：如果这些仍然没有返回任何内容，您需要确保添加

WebDriverWait

并等待可点击。
