The tagName
method returns the name of the tag in capital letters when used on an HTML DOM. For an XML DOM tree it returns the tag name as typed. Documentation

57,712 PointsYep - you need to compare it to the uppercase version of the HTML tag, without the angle brackets. So
<li>
is returned bytagName
as a string of"LI"
, a<div>
is returned as"DIV"
etc.Dskellth theFirst

Courses Plus Student 6,854 PointsIt doesn't matter. I tried using strictly equals (===) with lower case 'li'. Still doesn't work. The returned tag name is always in the canonical uppercase form.
