:first-child is not working properly about php-simple-html-dom-parser HOT 2 OPEN

the first child of .links > ul > li is a, so .links > ul > li:first-child > a equates to .links > ul > a > a, hence returning false.

What you describe is not a CSS behavior. The :first-child in CSS is applied on set of already selected elements and filter only elements which are situated as the first element in its parent.

When I use an example from my first comment .links > ul > li:first-child matches first li element - entire li element, not only a element.

When I use div > div:first-child it matches nothing because first element of root div is a and first element of div.links is ul -> there is no div element inside of another div at first place.

I made a mistake in my first comment, selector .links > ul > li:first-child > a matches by CSS specification:

<a href="https://github.com/">link 1</a>
