How can the issue of skipping certain nodes in an XML file be addressed when using a while loop in PHP?

When using a while loop to parse an XML file in PHP, the issue of skipping certain nodes can be addressed by checking the node's name before processing it. This can be done by using the `nodeName` property of the XML node object to determine if it should be skipped or not.

$xml = new SimpleXMLElement($xmlString);

foreach($xml->children() as $node) {
    // Skip processing if node name is 'skip'
    if($node->getName() === 'skip') {
        continue;
    }

    // Process the node
    // ...
}
