Add rss node for Google Shopping

[dutom007]

Hi,

I want to use your library for Google shopping. I don't understand how I can add rss node like :

<?xml version='1.0' encoding='UTF-8'?>
<rss version='2.0' xmlns:g='http://base.google.com/ns/1.0'>

  <title>Google Shopping</title>

Issues are for bugs, Q&A for usage questions. Currently have no time to give an in depth answer.

I understand.

I search but found nothing on exemples or tests.

I check source to understand more without success

Hello! I've made it work with the following:
I'm using a collection with data like:

"id" => "922051"
"link" => ""
"item_group_id" => "999775638"
"brand" => ""
"image_link" => ""
"additional_image_link" => array:3 [▶]
"size" => array:1 [▶]
"identifier_exists" => "no"
"condition" => "new"
"adult" => "no"
"is_bundle" => "no"
"availability" => "in_stock"
"title" => "product name"
"description" => array:1 [▶]
"price" => "price USD"
"sale_price" => "sale_price USD"
"google_product_category" => 1831
"product_type" => "Sweaters"
"gender" => "female"

You should have some sort for adding the namespace to each key (something like this):

$collection->map( function ($element) {
...
foreach ($element->attributesToArray() as $key => $attribute)
            {
                $element["g:" . $key] = $attribute;
                unset($element[$key]);
            }
...
})

Also you should key by item each element (where g:id is my product unique key):

$collection->map( function ($element) {
...
})->keyBy(function ($element) {
            //Custom key, as noted by Spatie/ArrayToXml. @see https://github.com/spatie/array-to-xml#using-custom-keys
            return "__custom:item:".$element["g:id"];
})

finally name the root element rss and set the xmlns attribute:

$collectionAsArray = $collection->toArray();
$xml = ArrayToXml::convert($collectionAsArray, [
            'rootElementName' => 'rss',
            '_attributes' => [
                'xmlns:g' => 'http://base.google.com/ns/1.0',
            ],
        ], true, 'UTF-8', '1.0', []);

Hope it helps!
