NoSuchElementException using Selenium Webdriver

Question

Below is the simple code to click an object using xpath.

I have located the xpath and performed the desired operation but still "NoSuchElementException" is thrown.

String localobject=OR.getProperty(object); //Obtaining xpath from object repository

we = driver.findElement(By.xpath(""+localobject+"")); 

executor.executeScript("arguments[0].click();", we);

Below is the trace:

Answer 1

When you obtain the xpath from object repository ensure that you invoke it as a String as follows :

we = driver.findElement(By.xpath(localobject));

Your error will help you:

The expression #//*[text()\=\'Log\ Out\'] is definitely not a valid css selector. Currently CSS_Selectors doesn't supports text() attribute.

Again the expression //*[text()='Log Out'] is not a valid id but a potential xpath
