Website scaping using DOMDocument

[Raex]

Hi, I have a php code that could extract the categories and display them. However, I still can't extract the numbers that goes along with it too(without the bracket). 

 

This is my code:

<?php
$grep = new DoMDocument();
@$grep->loadHTMLFile("http://www.lelong.com.my/Auc/List/BrowseAll.asp");

$finder = new DomXPath($grep);
$class = "CatLevel1";
$nodes = $finder->query("//*[contains(@class, '$class')]");

foreach ($nodes as $node) {
    $span = $node->childNodes;
        echo $span->item(0)->nodeValue."<br>";
}
?>

This is my desired output:

Arts, Antiques & Collectibles : 9768
B2B & Industrial Products : 2342
Baby : 3453
etc...

Any help is appreciated. Thanks!
