I am trying to use a ternary operator to check if the value of an XML element is null. If it is then I want the variable to be one thing. If not then I would like it to return the value of element. This is what I have so far.

var rating = data.getElementsByTagName(overall_average)[0].childeNodes[0].length > 0 ? data.getElementsByTagName(overall_average)[0].childeNodes[0].nodeValue : It is empty;

The shortest way:

var rating = (data.getElementsByTagName('overall_average')[0].childNodes[0] || {}).nodeValue || 'It is empty';
