Filters the post content for use in feeds.

$content string

The current post content.

$feed_type string

Type of feed. Possible values include 'rss2', 'atom'.
Default 'rss2'.

• The “the_content_feed” filter is used to filter the content of the post after it is retrieved from the database and filtered by “the_content” hook and before it is sent to RSS reader (or browser).
• The filter callback function must return the content after it is finished processing, or feed readers will see a blank item and other plugins also filtering the feed content may generate errors.
