Use Chrome’s Console to check the validity of css_selector and xpath

Check css_selector

And the $(css_selector)? (css_selector)

The former lists all matched elements, while the latter forms an array of matched elements. (Clicking on each returned element will locate the IMG element on the page and the specific location in the HTML.)

Check the xpath

$x(path)

$x(path) returns an array of all elements matched by xpath.
