FindElement() for number strings not working Eg: driver.FindElement(By.Name("2")).Click();

[lagori]

Hi,

While finding an element with number string eg: driver.FindElement(By.Name("2")).Click();
is giving and error as below:
Error Message:
OpenQA.Selenium.WebDriverException : Selector strategy 'css selector' with value '*[name ="\32 "]' is not supported

I tried with the escape sequence as well but had no luck.

That is weird, I would not expect a \3 in that error message *[name ="\32 "].

It could be that the SimpleCssAttributeRegex (which is not so simple) does not work correctly. I'll check. See

FlaUI.WebDriver/src/FlaUI.WebDriver/Controllers/FindElementsController.cs

Line 126 in 8c02962

private static Regex SimpleCssAttributeSelectorRegex = new Regex(@"^\*?\[\s*(?<ident>-?(?<nmstart>[_a-z]|[\240-\377])(?<nmchar>[_a-z0-9-]|[\240-\377])*)\s*=\s*(?<string>(?<string1>""(?<string1value>([^\n\r\f\\""]|(?<escape>\\[^\r\n\f0-9a-f]))*)"")|(?<string2>'(?<string2value>([^\n\r\f\\']|(?<escape>\\[^\r\n\f0-9a-f]))*)'))\s*\]$", RegexOptions.Compiled | RegexOptions.IgnoreCase);

Hi @lagori , this seems to be an issue in the Selenium .NET client that translates By.Name("2") into *[name ="\32 "]. Could you log this issue at https://github.com/SeleniumHQ/selenium/issues?
