Question

Get child node based on a specific parent

function(Crawler $node,){
    $node->filter('this>ul');
}

How can I get a $node children，that does not contain a grandson like the CSS selector #parent>child ?

Answer 1

1. You are using CSS selector.
2. There aren't any this or parent selector in CSS.
3. You should use just $node->filter('>ul');
