How to chain in phpquery (almost everything can be a chain)

Good day everyone, I'm very new with phpquery and this is my first post here at stackoverflow for a reason that i cant find the correct for syntax for the phpquery chaining. I know someone knows what i been looking for.

I only want to remove the a certain div inside a div.

 <div id = "content"> 
        <p>The text that i want to display</p>
        <div class="node-links">Stuff i want to remove</div>
 </content>

This few lines of codes works perfect

 pq('div.node-links')->remove();
 $text = pq('div#content');
 print $text; //output: The text that i want to display

But when I tried

$text = pq('div#content')->removeClass('div.node-links'); //or
$text = pq('div#content')->remove('div.node-links');

 //output: The text that i want to display (+) Stuff i want to remove

Can someone tell me why the second block of code is not working?

Thanks!

Solution

The first line of code will only work if your trying to remove the class from div.node-links, it won't remove the node.

If you are trying to remove the class you need to change it from:

$text = pq('div#content')->removeClass('div.node-links');
// to
$text = pq('div#content')->find('.node-links')->removeClass('node-links')->end();

which will output:

<div id="content">
    <p>The text that i want to display</p>
    <div>Stuff i want to remove</div>
</div>

As for the second line of code.. I'm not exactly sure why it is not working, it seems like your not selecting .node-links but I was able to get the desired results using these.

// $markup = file_get_contents('test.html');
// $doc = phpQuery::newDocumentHTML($markup);
$text = $doc->find('div#content')->children()->remove('.node-links')->end();

// or 

$text = pq('div#content')->find('.node-links')->remove()->end();

// or 

$text = pq('div#content > *')->remove('.node-links')->parent();

Hope that helps
