interface ParserInterface (View source)

Defines an interface for aggregator parser implementations.

A parser converts feed item data to a common format. The parser is called at the second of the three aggregation stages: first, data is downloaded by the active fetcher; second, it is converted to a common format by the active parser; and finally, it is passed to all active processors which manipulate or store the data.

Methods

bool
parse(FeedInterface $feed)

Parses feed data.

Details

bool parse(FeedInterface $feed)

Parses feed data.

Parameters

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.
