I have html file which looks like this:

Answer 1

Passing a DomNode to foreach will not allow you to iterate through its childen, you can easily get the list of lis and iterate through them.

<?php
    $dom = new DOMDocument();
    $dom->loadHTML($data);
    $postalCodesList = $dom->getElementsByTagName('ul');
    foreach ($postalCodesList->item(0)->getElementsByTagName('li') as $postalCodesList) {
        echo $postalCodesList->nodeValue.'<br />';                    
    }
?>
