C# Selenium 导航到特定页面上的统计信息

Question

我正在使用 C# 和 Selenium。

在此页面上，我想点击“统计”： https ://eatradingacademy.com/software/forex-historical-data/

我尝试点击几个修改后的代码。 相当尝试和错误。 直到现在我才理解 XPath，但我正在研究它。

这里有人可以帮我吗？ 单击此链接需要哪些代码行？

 //webdriver.FindElement(By.XPath("//a[text()='Settings']")).Click(); //webdriver.FindElement(By.XPath("//li[@class='nav-item']/a[text()='Settings']")).Click(); // webdriver.FindElement(By.XPath("//li/a/span[.='Settings']")).Click(); //webdriver.FindElement(By.XPath("//a[contains(.,'Settings')]")).Click(); //webdriver.FindElement(By.XPath("//a[contains(text(),'Settings')]")).Click();

编辑：添加代码：

Answer 1

这是一种特殊情况，因为您要单击的元素位于 iFrame 中。
要定位此类元素，您首先必须将焦点切换到 iFrame。
你可以这样做：

webdriver.SwitchTo().Frame(webdriver.findElement(By.id("data-app-frame"));

之后，您可以在 iFrame 中找到该元素。 在这种情况下，我建议结合使用类和文本，因为如果您只搜索文本，则可能会找到另一个仅包含“设置”或“统计”一词的元素。
这将导致以下行：

webdriver.FindElement(By.XPath("//a[@class='nav-link panel-switch' and contains(text(), 'Statistics')]")).Click();

更新：我认为问题可能是元素不在您的视口中。 在尝试单击它之前，我将代码更改为滚动到该元素。
尝试这个：

webdriver.SwitchTo().Frame(webdriver.FindElement(By.Id("data-app-frame")));
var statistics = webdriver.FindElement(By.XPath("//a[@class='nav-link panel-switch' and contains(text(), 'Statistics')]"));
Actions actions = new Actions(webdriver);
actions.MoveToElement(statistics);
actions.Perform();
statistics.Click();

Answer 2

试试下面的 XPath

//a[translate(normalize-space(.), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')='statistics']
