我一直在讨论How to automate shadow DOM elements using selenium?讨论与#shadow-root(open)元素一起工作.

在通过Selenium访问url chrome：// settings / clearBrowserData时出现的清除浏览数据弹出窗口中找到清除数据按钮的过程中,我无法找到以下元素：

#shadow-root (open)

快照：

使用Selenium以下是我的代码试验和遇到的相关错误：

>尝试1：

WebElement root5 = shadow_root4.findElement(By.tagName("settings-privacy-page"));

>错误：

Exception in thread "main" org.openqa.selenium.JavascriptException: javascript error: b.getElementsByTagName is not a function

>尝试2：

WebElement root5 = shadow_root4.findElement(By.cssSelector("settings-privacy-page"));

>错误：

Exception in thread "main" org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"css selector","selector":"settings-privacy-page"}

>尝试3：

WebElement root5 = (WebElement)((JavascriptExecutor)shadow_root4).executeScript("return document.getElementsByTagName('settings-privacy-page')[0]");

>错误：

Exception in thread "main" java.lang.ClassCastException: org.openqa.selenium.remote.RemoteWebElement cannot be cast to org.openqa.selenium.JavascriptExecutor

如果它有用,初始代码块(直到上面的行)完美运行：

driver.get("chrome://settings/clearBrowserData");
WebElement root1 = driver.findElement(By.tagName("settings-ui"));
WebElement shadow_root1 = expand_shadow_element(root1);

WebElement root2 = shadow_root1.findElement(By.cssSelector("settings-main#main"));
WebElement shadow_root2 = expand_shadow_element(root2);

WebElement root3 = shadow_root2.findElement(By.cssSelector("settings-basic-page[role='main']"));
WebElement shadow_root3 = expand_shadow_element(root3);

WebElement root4 = shadow_root3.findElement(By.cssSelector("settings-section[page-title='Privacy and security']"));
WebElement shadow_root4 = expand_shadow_element(root4);

PS：expand_shadow_element()完美无瑕.

有人可以帮帮我吗？
