Why can't Webdriver find an element through xpath?

Question

My code can't find a registration link with XPath. Same problem using CSSSelector.

driver = new ChromeDriver(options);
driver.Navigate().GoToUrl("https://www.goldtoe.com/state/landing");         
var LoginLink = driver.FindElement(By.XPath("//li[@class='hidden-xs myAccountMenu']//a[contains(text(),'Sign In/Register')] "));
LoginLink.Click();

Message:

> OpenQA.Selenium.NoSuchElementException : no such element: Unable to
> locate element: {"method":"xpath","selector":"//li[@class='hidden-xs
> myAccountMenu']//a[contains(text(),'Sign In/Register')] "}   (Session

Answer 1

I think you need an escape character for 'Sign In/Register' string, specifically for '/' special character. So, try 'Sign In\/Register' instead. Use '\' as the escape character.
