Challenge: Filter results to show elements with no content
(upbeat music) - [Instructor] I have another code challenge for you. This time we're looking for Hue values or Saturation values that have no content. So we're going to look inside this file, WebColorsB.xml, and you're going to write a query expression that finds the Hue elements that have no content. And once that's working, then you're going to modify that query expression to find a Hue and Saturation elements that have no content. And the way you do that, is use the & to combine the first and second part of a where clause. Now it's your turn. If you are uncertain how to solve this, refer to the earlier examples, or jump into the next video and follow along with my solution.
