-The template consists of html containing placeholders that will be replaced by fields from the item: +In the template placeholders that will be replaced by fields from the item:
-  * [CONTENT]+

 +  * [AUTHOR]
 +  * [DESCRIPTION]

-The source of the content depends on the type of feed. For an RSS feed the ''description'' field is used if present, otherwise the ''content'' field. For an Atom feed the ''summary'' field is used if present, otherwise the ''content'' field. +A feed item may provide a short summary instead of, or as well as, the full content. The [DESCRIPTION] placeholder will be replaced by the RSS ''description'' or Atom ''summary'' element if present, otherwise replaced by the full content. The [CONTENT] placeholder will be replaced by the ''content'' element from the feed if present, otherwise replaced by the short content.
-The published date is formatted using a configuration setting. The default is to display as dd/mm/yyyy hh:mm.+

 +=== Formatting the published date ===
 +
 +If the php ''intl'' extension is enabled then the plugin will format the published date in the language of the feed, which is identified by the ''<language>'' element. The date is formatted using a format string containing placeholders as explained at [[https://unicode-org.github.io/icu/userguide/format_parse/datetime/#date-field-symbol-table| https://unicode-org.github.io/icu/userguide/format_parse/datetime/#date-field-symbol-table]]. This allows month and weekday names to be in the feed's language. For example, this shows the published date formatted in Spanish
 +{{:plugin:rss12.png?nolink&500|}}
 +
 +If the php ''intl'' extension is not enabled or the feed does not identify its language then the plugin will format the published date using the php ''date()'' formatting as described at [[https://www.php.net/manual/en/datetime.format.php|https://www.php.net/manual/en/datetime.format.php]]. In this case month and weekday names will be in English.

 +==== Deleting all items ====
  
 +During testing of an RSS campaign it can be useful to remove all items so that the feed can be re-fetched. The page has a **Reset feeds** function which will delete all items and reset the ''etag'' and ''lastmodified'' fields for each feed.

-When an item's URL field (taken from the ''link'' element) is a URL to a YouTube video or to a pdf file then the plugin can generate special content instead of using the ''summary'', ''description'' or ''content'' elements. +
- +
-<code html><link href="https://www.youtube.com/watch?v=99999999"/> +
-<link href="https://example.com/document.pdf"/></code> +

-For a YouTube video the content will be an iframe element that refers to the video. This is not really useful because many email clients will not display an iframe element.+
  
-<code html><iframe width="560" height="315" src="//www.youtube.com/embed/99999999" frameborder="0"></iframe></code>+The plugin used to have settings for allowing only whitelisted tags, generating special content for a Youtube URL, and specifying the maximum size of the HTTP response. These were specific to the Picofeed package which is no longer used.
  
-For a pdf file the content will be a link to the file. +There was also a setting for whether to use a feed item's ''description'' element or ''summary'' element. This setting is no longer needed because the plugin now provides a ''[DESCRIPTION]'' placeholder in addition to the ''[SUMMARY]'' placeholder.
