Loop through an XML object with SimpleXML
SimpleXML doesn't have a getElementsByTagName()
method (DOMDocument does).
In SimpleXML, the object (e.g $xml
) is treated as the root element. So you can loop through the product items like so:
$xml = simplexml_load_string($xmlString);
foreach($xml->products->item as $item)
{
echo (string)$item->product_id;
echo (string)$item->model;
}
Example of building a devices associative array:
$devices = array();
$xml = simplexml_load_string($xmlString);
foreach($xml->products->item as $item)
{
$device = array();
foreach($item as $key => $value)
{
$device[(string)$key] = (string)$value;
}
$devices[] = $device;
}
print_r($devices);
Outputs:

I don't want to spoil the existing answer as it is answering correct an in a general fashion.
For your concrete requirements as with your XML there aren't any attributes and you're just looking for the element-name => node-value pairs here, there is one function that comes to mind in conjunction with SimpleXMLElement here: get_object_vars
.
It is useful whenever you convert an object into an array and as SimpleXMLElement turns element names into object property names and the node-values as those property values it's pretty straight forward here:
$xml = simplexml_load_string($buffer);
$items = $xml->products->item;
$devices = array_map('get_object_vars', iterator_to_array($items, FALSE));
print_r($devices);
The output is as suggested in the existing answer. And the online demo is here: https://3v4l.org/iQKQP
You will likely able to achieve similar results with casting to arrays (if not exactly the same with SimpleXML), however in this case as I wanted to map it, I needed a true function.
There is also the json-en- and -de-code doubling for converting complete trees, which comes in handy here, too:
$xml = simplexml_load_string($buffer);
$items = $xml->products;
$devices = json_decode(json_encode($items), TRUE)['item'];
The output then again is exactly as the existing answer. And the online demo again is here: https://3v4l.org/ToWOs
Hope this is helpful and widens the view a bit.
