Inherited Variables

Inherited Methods

Class: XML_Feed_Parser_RSS1

XML_Feed_Parser_RSS1::getAuthor(): Dublin Core provides the dc:creator, dc:contributor, and dc:publisher elements for defining authorship in RSS1. We will try each of those in turn in order to simulate the atom author element and will return it as text.
XML_Feed_Parser_RSS1::getEntryById(): This is not really something that will work with RSS1 as it does not have clear restrictions on the global uniqueness of IDs. We will employ the _very_ hit and miss method of selecting entries based on the rdf:about attribute.
XML_Feed_Parser_RSS1::getImage(): Get details of the image associated with the feed.
XML_Feed_Parser_RSS1::getLink(): In RSS1 a link is a text element but in order to ensure that we resolve URLs properly we have a special function for them.
XML_Feed_Parser_RSS1::getTextInput(): The textinput element is little used, but in the interests of completeness we will support it.

Class: XML_Feed_Parser_Type

XML_Feed_Parser_Type::addBase(): Gets us the xml:base data and then processes that with regard to our current link.
XML_Feed_Parser_Type::combineBases(): We have other methods which will traverse the DOM and work out the different xml:base declarations we need to be aware of. We then need to combine them.
XML_Feed_Parser_Type::count(): This function will tell us how many times the element $type appears at this level of the feed.
XML_Feed_Parser_Type::getCategory(): There is no single way of declaring a category in RSS1 or Atom as there is in RSS2.
XML_Feed_Parser_Type::getDate(): Get a date construct. We use PHP's strtotime to return it as a unix datetime
XML_Feed_Parser_Type::getEntryByOffset(): Pretty fundamental!
XML_Feed_Parser_Type::getText(): Get a text construct.
XML_Feed_Parser_Type::processXHTMLAttributes(): We need a couple of methods to access XHTML content stored in feeds.
XML_Feed_Parser_Type::traverseNode(): We need a couple of methods to access XHTML content stored in feeds.

Method Detail

getContent [line 109]

string|false getContent(
)

The official way to include full content in an RSS1 entry is to use the content module's element 'encoded'. Often, however, the 'description' element is used instead. We will offer that as a fallback.

[ Top ]

getEnclosure [line 141]

false getEnclosure(
)

How RSS1 should support for enclosures is not clear. For now we will return false.

[ Top ]

getId [line 94]

string|false getId(
)

There is no established way of showing an ID for an RSS1 entry. We will simulate it using the rdf:about attribute of the entry element. This cannot be relied upon for unique IDs but may prove useful.
