C＃Selenium无法通过WebDriverWait找到元素，我可以手动查看并单击它

Question

Element im trying to locate:

        WebDriverWait wait = new WebDriverWait(browser, TimeSpan.FromSeconds(60));
        wait.Until(ExpectedConditions.ElementExists(By.XPath("//use[@xlink:href='#core_mail']")));

        File.WriteAllText("html.txt", browser.PageSource);

that just times out.. and the page loads way before 60 seconds.

Answer 1

svg has a default namespace . You have to account for it:

//svg:use[@xlink:href='#core_mail']

Or ignore it with local-name() :

//*[local-name() = 'use' and @xlink:href='#core_mail']

Though, to be fair, you don't have to dive into the markup that deeply, your "email" button is much higher in the tree - see the very first parent element partially visible on the screenshot - that's your desired element you probably want to locate instead.
