C# Selenium 导航到特定页面上的统计信息

Question

I am working with C# and Selenium.

On this Page i want to click on "Statistics": https://eatradingacademy.com/software/forex-historical-data/

I tried out to click with several modified codes. Fairly try & error. I dont understand XPath until now, but i am working on it.

Can someone here help me out? What lines of Code are needed to click this Link?

 //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();

Code of Page

Answer 1

This is a special case because the element you want to click is located in an iFrame.
To locate such element, you'll first have to switch the focus to the iFrame.
You can do this like this:

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

After that you can locate the element within the iFrame. I would suggest taking a combination of class and text in this case because if you only search for the text, another element which contains just the word 'Settings' or 'Statistics' may be located instead.
This would result in following line:

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

Update: I think the problem may be the element is not in your viewport. I changed the code to scroll to the element before trying to click it.
Try this:

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

Try below XPath

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