5,886 PointsXpath review quiz-Question on "Given the HTML code, how many elements would the following call return?"
On the Introduction to Selenium class, on of the Xpath review quiz (after Fork in the Xpath section), gives students some HTML code and asks how many elements would be found using a particular code string [starts with driver.findElement(By.xpath]. I'm not sure why this line of code would only find one instance of "sample" instead of two. I'm not sure if it's because the command used is findElement instead of findElements. Can you clear this up for me?
Thanks,
Jan

On the other hand, findElements (plural) returns a list of all the elements that match. If none are found, it returns an empty list with no error.
