Inherited Methods

Class: XML_Feed_Parser_Atom

XML_Feed_Parser_Atom::getCategory(): Get a category from the entry.
XML_Feed_Parser_Atom::getEntryById(): Implement retrieval of an entry based on its ID for atom feeds.
XML_Feed_Parser_Atom::getLink(): This element must be present at least once with rel="feed". This element may be present any number of further times so long as there is no clash. If no 'rel' is present and we're asked for one, we follow the example of the Universal Feed Parser and presume 'alternate'.
XML_Feed_Parser_Atom::getPerson(): Retrieves data from a person construct.
XML_Feed_Parser_Atom::getText(): Retrieves an element's content where that content is a text construct.
XML_Feed_Parser_Atom::parseTextConstruct(): Extract content appropriately from atom text constructs

Class: XML_Feed_Parser_Type

XML_Feed_Parser_Type::addBase(): Determine whether we need to apply our xml:base rules
XML_Feed_Parser_Type::combineBases(): Utility function to help us resolve xml:base values
XML_Feed_Parser_Type::count(): Count occurrences of an element
XML_Feed_Parser_Type::getCategory(): Apply various rules to retrieve category data.
XML_Feed_Parser_Type::getContent(): Get content from RSS feeds (atom has its own implementation)
XML_Feed_Parser_Type::getDate(): Return a date in seconds since epoch.
XML_Feed_Parser_Type::getEntryByOffset(): Get an entry by its position in the feed, starting from zero
XML_Feed_Parser_Type::getSchemaDir(): Get directory holding RNG schemas. Method is based on that found in Contact_AddressBook.
XML_Feed_Parser_Type::getText(): Get a text construct.
XML_Feed_Parser_Type::hasKey(): Checks if this element has a particular child element.
XML_Feed_Parser_Type::processXHTMLAttributes(): Part of our xml:base processing code
XML_Feed_Parser_Type::traverseNode(): Part of our xml:base processing code

Method Detail

getAuthor [line 110]

string getAuthor(
array
$arguments)

Provides access to specific aspects of the author data for an atom entry

Author data at the entry level is more complex than at the feed level. If atom:author is not present for the entry we need to look for it in an atom:source child of the atom:entry. If it's not there either, then we look to the parent for data.

Parameters:

array $arguments —

getContent [line 153]

string|false getContent(
mixed
$method, [mixed
$arguments = array()])

Returns the content of the content element or info on a specific attribute

This element may or may not be present. It cannot be present more than once. It may have a 'src' attribute, in which case there's no content If not present, then the entry must have link with rel="alternate". If there is content we return it, if not and there's a 'src' attribute we return the value of that instead. The method can take an 'attribute' argument, in which case we return the value of that attribute if present. eg. $item->content("type") will return the type of the content. It is recommended that all users check the type before getting the content to ensure that their script is capable of handling the type of returned data. (data carried in the content element can be either 'text', 'html', 'xhtml', or any standard MIME type).

Overrides XML_Feed_Parser_Type::getContent() (Get content from RSS feeds (atom has its own implementation))

getEnclosure [line 194]

array|false getEnclosure(
string
$method, [array
$arguments = array()])

For compatibility, this method provides a mapping to access enclosures.

The Atom spec doesn't provide for an enclosure element, but it is generally supported using the link element with rel='enclosure'.

Parameters:

string	`$method`	—	- for compatibility with our __call usage
array	`$arguments`	—	- for compatibility with our __call usage

getSource [line 231]

XML_Feed_Parser_Atom|false getSource(
)

Get details of this entry's source, if available/relevant

Where an atom:entry is taken from another feed then the aggregator is supposed to include an atom:source element which replicates at least the atom:id, atom:title, and atom:updated metadata from the original feed. Atom:source therefore has a very similar structure to atom:feed and if we find it we will return it as an XML_Feed_Parser_Atom object.
