Include a new XML child element using PHP

I've encountered an issue with my PHP code while trying to add multiple nodes from an XML file. Currently, the code only adds the first node, but I need it to include all child nodes under the name 'node'.

XML Structure:

<root>
<result>
<node>
<someting>asdasd</something>
</node>
<node>
<someting>asdasd</something>
</node>
  </result>
        <error/>
      </root>

Desired XML Output:

<root>
<result>
<node>
<someting>asdasd</something>
<Shipping_Cost>9</Shipping_Cost>
</node>
<node>
<someting>asdasd</something>
<Shipping_Cost>9</Shipping_Cost>
</node>
  </result>
        <error/>
      </root>

Current PHP Function:

function fn_add_shipping($xmlFileToLoad, $destination)
{
    $xmlFileToLoad = 'shipping.xml';
    $dom = new DOMDocument();
    $dom->load($xmlFileToLoad);
    $shipping = $dom->getElementsByTagName('node')->item(0);
    $ship = $dom->createElement('Shipping_Cost', '9');
    $shipping->appendChild($ship);
    $dom->save($destination);
    return $destination;
}

Apologies for the confusion earlier on your query. It seems I misunderstood the purpose of the 2nd XML file that you requested to be generated by the PHP method. Upon reviewing it now, I comprehended where the issue lies. You have only invoked the append function once. To resolve this, you should iterate through each node and call the append function before writing the results to the target XML file.

Consider implementing something along these lines:

function fn_create_shipping($sourceXmlFile, $destination)
{
    $sourceXmlFile = 'shipping.xml';
    $dom = new DOMDocument();
    $dom->load($sourceXmlFile);
    $shippingNodes = $dom->getElementsByTagName('node');
    
    for ($x=0; $x<$shippingNodes->length; $x++)
    {
        $newShippingNode = $dom->createElement('Shipping_Cost', '9');
        $shippingNodes[$x]->appendChild($newShippingNode);
    }
    
    $dom->save($destination);
    return $destination;
}
