Horde_Feed_Atom extends Horde_Feed_Base

Atom feed class

The Horde_Feed_Atom class is a concrete subclass of the general Horde_Feed_Base class, tailored for representing an Atom feed. It shares all of the same methods with its parent. The distinction is made in the format of data that Horde_Feed_Atom expects, and as a further pointer for users as to what kind of feed object they have been passed.

Methods

__construct()

Feed constructor

public __construct([mixed $xml = null ][, string $uri = null ][, Horde_Http_Client $httpClient = null ]) : mixed

Parameters
$xml : mixed = null

The feed as a string, a DOMElement, or null.

$uri : string = null

The full URI of the feed, or null if unknown.

$httpClient : Horde_Http_Client = null

link()

Easy access to <link> tags keyed by "rel" attributes.

public link([string $rel = null ]) : mixed
Parameters
$rel : string = null

The "rel" attribute to look for.

Tags
TODO

rationalize this with other __get/__call access

If $elt->link() is called with no arguments, we will attempt to return the value of the tag(s) like all other method-syntax attribute access. If an argument is passed to link(), however, then we will return the "href" value of the first tag that has a "rel" attribute matching $rel:

$elt->link(): returns the value of the link tag. $elt->link('self'): returns the href from the first in the entry.
