Symphony, how to parse an RSS feed on Twig

Question

For example, in PHP, a way to parse an RSS feed might be:

<?php $rss = simplexml_load_file('http://blog.wordpress_site.com/feed/'); {{ rss }} foreach ($rss->channel->item as $item) { echo $item->title; echo $item->link; echo $item->description; echo $item->guid; } ?> 

How to do it on Twig?

UPDATE . Thanks to the answer, I got it. Now he gets this by element, but not some fields, such as an image, category or message text:

 SimpleXMLElement {#955 ▼ +"title": "Website. Description of the website" +"link": "http://blog.website.com/liktothepost" +"pubDate": "Fri, 17 Feb 2017 07:56:43 +0000" +"category": SimpleXMLElement {#1131} +"guid": "http://blog.website.com/?p=400" +"description": SimpleXMLElement {#953} } 

Answer 1

You would create a controller with an action to transfer the object to your Twig file, which you want to do as follows:

 public function viewRSSAction(Request $request){ $rss = simplexml_load_file('http://blog.wordpress_site.com/feed/'); return $this->render('my_rss.html.twig', array( 'rss' => $rss, )); } 

Then your my_rss.html.twig might look like this:

 {% for item in rss %} {{ item.title }} {{ item.link }} {{ item.description }} {{ item.guid }} {% endfor %}
