Remove element tagging - $dom->createElement

Hi,
I have a chunk from some code that creates an XML file for an purchase order, I need to alter this as now need it in TRADACOM format so all elements are just a text file. I need some pointers on how to unravel the createelement parts:

So, instead of this result:

<StartOfTransmission>
    <SenderId>1234567890:A Company</SenderId>
    <ReceiverId>5013546066966:B Company</ReceiverId>
    <TRANSDATE>23-10-2014</TRANSDATE>
    <TRANSTIME>15:51:05</TRANSTIME>
    <SenderReference>000000000000000</SenderReference>
    <ApplicationReference>ORDHDR</ApplicationReference>
  </StartOfTransmission>

I end up with:

1234567890:A company:5013546667966:B Company:23-10-2014:15:51:05:000000000000000:ORDHDR'

        //start transmission
        $sot = $dom->createElement('StartOfTransmission');
        $arr_foo = array(
              'SenderId'=>$this->_sender_id,
              'ReceiverId'=>$this->_receiver_id,
              'TRANSDATE'=>date('d-m-Y'),
              'TRANSTIME'=>date('H:i:s'),
              'SenderReference'=>'000000000000000',
              //'ReceiverReference'=>'',
              'ApplicationReference'=>'ORDHDR',
              );
        foreach ($arr_foo as $key => $value) {
            $item = $dom->createElement($key, $value);
            $sot->appendChild($item);  
        }
        
        $element->appendChild($sot);
        unset($sot);
        //end trammission

Hope someone can help?

Cool, thanks, have tried to 'wrap' this around the code below but cannot get it correct, is there a way to forget creating the xml and go straight for the text string?:

       //start transmission
        $sot = $dom->createElement('StartOfTransmission');
        $arr_foo = array(
              'SenderId'=>$this->_sender_id,
              'ReceiverId'=>$this->_receiver_id,
              'TRANSDATE'=>date('d-m-Y'),
              'TRANSTIME'=>date('H:i:s'),
              'SenderReference'=>'000000000000000',
              //'ReceiverReference'=>'',
              'ApplicationReference'=>'ORDHDR',
              );
        foreach ($arr_foo as $key => $value) {
            $item = $dom->createElement($key, $value);
            $sot->appendChild($item);  
        }
       
        $element->appendChild($sot);
        unset($sot);
        //end trammission

This should work, however it cannot be tested without being in the object context.

$arr_foo = array(
              'SenderId'=>$this->_sender_id,
              'ReceiverId'=>$this->_receiver_id,
              'TRANSDATE'=>date('d-m-Y'),
              'TRANSTIME'=>date('H:i:s'),
              'SenderReference'=>'000000000000000',
              //'ReceiverReference'=>'',
              'ApplicationReference'=>'ORDHDR',
              );

// MAKE A COLON-SEPARATED STRING
$str = implode(':', $arr_foo);
echo PHP_EOL . htmlentities($str);
