Parses feed data.

Parameters

\Drupal\aggregator\FeedInterface $feed: An object describing the resource to be parsed. $feed->source_string->value contains the raw feed data. Parse the data and add the following properties to the $feed object:

• description: The human-readable description of the feed.
• link: A full URL that directly relates to the feed.
• image: An image URL used to display an image of the feed.
• etag: An entity tag from the HTTP header used for cache validation to determine if the content has been changed.
• modified: The UNIX timestamp when the feed was last modified.
• items: An array of feed items. The common format for a single feed item is an associative array containing:
  • title: The human-readable title of the feed item.
  • description: The full body text of the item or a summary.
  • timestamp: The UNIX timestamp when the feed item was last published.
  • author: The author of the feed item.
  • guid: The global unique identifier (GUID) string that uniquely identifies the item. If not available, the link is used to identify the item.
  • link: A full URL to the individual feed item.

Return value

bool TRUE if parsing was successful, FALSE otherwise.
