Adding Child element to XML

Question

I have XML of the form

$xml=<<<EOD
<?xml version="1.0" encoding="utf-8"?>
<CompleteSaleRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<RequesterCredentials>
<eBayAuthToken>AUTH_TOKEN_VALUE</eBayAuthToken>
</RequesterCredentials>
<ItemID>ItemIDVALUE</ItemID>
<TransactionID>TransactionIDVALUE</TransactionID>
<Shipped>1</Shipped>
<Paid>1</Paid>
  <Shipment>
    <ShipmentTrackingDetails>
   <ShipmentTrackingNumber>$trackingNo</ShipmentTrackingNumber>
      <ShippingCarrierUsed>UPS</ShippingCarrierUsed>
    </ShipmentTrackingDetails>
    <ShippedTime>2014-09-30 12:41:59.202303</ShippedTime>
    </Shipment>
<ErrorLanguage> string </ErrorLanguage>
EOD;

I want to append more ShipmentTrackingDetails portion using PHP, I need the resulting XML like this:

$xml=<<<EOD
<?xml version="1.0" encoding="utf-8"?>
<CompleteSaleRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<RequesterCredentials>
<eBayAuthToken>AUTH_TOKEN_VALUE</eBayAuthToken>
</RequesterCredentials>
<ItemID>ItemIDVALUE</ItemID>
<TransactionID>TransactionIDVALUE</TransactionID>
<Shipped>1</Shipped>
<Paid>1</Paid>
  <Shipment>
    <ShipmentTrackingDetails>
   <ShipmentTrackingNumber>$trackingNo</ShipmentTrackingNumber>
      <ShippingCarrierUsed>UPS</ShippingCarrierUsed>
    </ShipmentTrackingDetails>

 <ShipmentTrackingDetails>
   <ShipmentTrackingNumber>$trackingNo2</ShipmentTrackingNumber>
      <ShippingCarrierUsed>UPS</ShippingCarrierUsed>
    </ShipmentTrackingDetails>

 <ShipmentTrackingDetails>
   <ShipmentTrackingNumber>$trackingNo3</ShipmentTrackingNumber>
      <ShippingCarrierUsed>UPS</ShippingCarrierUsed>
    </ShipmentTrackingDetails>
    <ShippedTime>2014-09-30 12:41:59.202303</ShippedTime>
    </Shipment>
<ErrorLanguage> string </ErrorLanguage>
EOD;

PHP Source:

$sxe = new SimpleXMLElement($xml); 
$track = $sxe->addChild('ShipmentTrackingDetails'); 
$track->addChild("ShipmentTrackingNumber", "9876"); 
$track->addChild("ShippingCarrierUsed", "USPS");

I am not getting how to do this using php. Please help in getting this working.

Thanks!

I got it, The dynamic part would be:

 $sxe = new SimpleXMLElement($xml);  
    $TrackingDetails = $sxe->Shipment->addChild('ShipmentTrackingDetails'); 
    $TrackingDetails->addChild("ShipmentTrackingNumber", $trackingMore); 
    $TrackingDetails->addChild("ShippingCarrierUsed", "UPS"); 
    $sxe->asXML("tracking.xml");
    $xml1 = $sxe->saveXML();

Where $xml is the original xml to which we want to add new child.
