Probably pure twig:

I am building an array from nodes taken from a RSS-feed where one of the keys contains a colon which of course breaks everything. Like so:

Node in feed:

<media:thumbnail url="stuff I like to get." />

My twig:

{% for node in feed %}
        {% set latestArticles = latestArticles|merge([{
                'timestamp': node.pubDate|atom,
                'title': node.title,
                'uri': node.link,
                'description': node.description,
                'thumbnail' : node.media:thumbnail,
            }]) %}
        {% endif %}
    {% endfor %}

So how do I get media:thumbnail?

I have tried different things but without luck.

  • Have you tried brackets notation, i.e. node['media:thumbnail']? Sep 10, 2018 at 5:17
  • Yes, I did. It says: Key "media:thumbnail" for array with keys "title, link, pubDate, category, guid, description, dc:creator" does not exist. Sep 10, 2018 at 5:44

    That suggests that the structure of the node object isn’t what you think it is. Try enabling devMode and do {{ dump(node) }} to see the object’s contents and structure Sep 10, 2018 at 16:48

    Haven’t thought about dump. No idea, why. You’re right, it’s an array. So the correct code is: 'img' : node['media:content'][1]['@url'] Thanks! Sep 10, 2018 at 17:14
  • @MarcusScheller would you mind adding that as an official answer in case it ends up helping someone in the future?

As @mats-mikkel-rummelhoff suggested, that data type is an array. So I was able to get the desired value by using:

'img' : node['media:content'][1]['@url']

Thanks, Mats.
