Create an RSS feed with content:encoded

[ryadbkr]

We've been trying to create an RSS feed containing
<content:encoded><![CDATA[ <p> no luck ]]></content:encoded>

we've tried creating an element with the CDATA as content but it seems the CDATA tag is being encoded (<content:encoded>&lt;![CDATA[), hence it's not well interpreted by the RSS/XML parser,

Is using CDATA within <content:encoded> supported? If no are you planing on adding it.

Thanks

Hi,

No, it's not supported and I don't plan to do so. If you need that feature you can:

• build your own standard and add it in the Specification provided to FeedIo
• submit a Pull Request to make feed-io support it in its actual standards

But I'm not in favor of the second one. It's an edge-case, I prefer to avoid having to support it in the long run.

Ok, for futur notes,
I added my own rule to transform certain elements to CDATA, but it was not sufficient since te default XML formatter https://github.com/alexdebril/feed-io/blob/main/src/FeedIo/Formatter/XmlFormatter.php#L65
always overrides it with an optionalField rule, so I had to also create a custom formatter in order to fix that.

        $rules = [];
        $optionalFields = $node->listElements();
        foreach ($optionalFields as $optionalField) {
            $rules[$optionalField] = new OptionalField($optionalField);
        }

        return array_merge($rules, $ruleSet->getRules());

Btw. one use case would be Facebook Instant Articles for which the content of the article needs to be in a <content:encoded> node with <![CDATA[ ... ]]> (at least according to their docs).

Sure thing, if it's really something valuable for your project then I think it's worth submitting a pull request 🙂
