How have foreach loop with this simplexml_load_string

Question

I am parsing xml using simplexml_load_string like this :

 $xml = simplexml_load_string($response);

        echo '{'.
            '"Date":"'.$xml->Date[0].'",'.
            '"Description":"'.$xml->ShipTos->ShipTo->ShippingGroups->ShippingGroup->OrderItems->OrderItem->Description[0].'",'. 
            '"Track":"'.$xml->Shipments->Shipment->Track[0].'"'.
            '}';

This works ok but if a node appears in the xml multiple times it only grabs it once. Can someone please help me understand how I would write a foreach loop specifically for the Description node?

simple_xml tends to make things, IMO harder to process, have you tried DOMDocument? $dates = $doc->getElementsByTagName("Date"); foreach( $dates as $date ) { } ? — Rahly

You are only referring to one instance of each SimpleXMLObject. For example $xml->Date[0] refers to the first occurence of a Date object only. To print all Date objects you need to loop through them

foreach( $xml->Date as $date ){
   print (string)$date;
}

Alternatively, you could use the children function:

foreach( $xml->children('Date') as $date ){
   print (string)$date;
}

$datebuffer;
$count = 0;
foreach($xml->Date as $date){
   $count++;
   datebuffer .= "Date:".$count ." ".$date; 
}

and so on...
