25 * This class provides support for RSS 1.0 entries. It will usually be called by
26 * XML_Feed_Parser_RSS1 with which it shares many methods.
28 * @author James Stewart <james@jystewart.net>
29 * @version Release: 1.0.3
30 * @package XML_Feed_Parser
32 class XML_Feed_Parser_RSS1Element extends XML_Feed_Parser_RSS1
35 * This will be a reference to the parent object for when we want
36 * to use a 'fallback' rule
37 * @var XML_Feed_Parser_RSS1
42 * Our specific element map
45 protected $map = array(
47 'title' => array('Text'),
48 'link' => array('Link'),
49 'description' => array('Text'), # or dc:description
50 'category' => array('Category'),
51 'rights' => array('Text'), # dc:rights
52 'creator' => array('Text'), # dc:creator
53 'publisher' => array('Text'), # dc:publisher
54 'contributor' => array('Text'), # dc:contributor
55 'date' => array('Date'), # dc:date
56 'content' => array('Content')
60 * Here we map some elements to their atom equivalents. This is going to be
61 * quite tricky to pull off effectively (and some users' methods may vary)
62 * but is worth trying. The key is the atom version, the value is RSS1.
65 protected $compatMap = array(
66 'content' => array('content'),
67 'updated' => array('lastBuildDate'),
68 'published' => array('pubdate'),
69 'subtitle' => array('description'),
70 'updated' => array('date'),
71 'author' => array('creator'),
72 'contributor' => array('contributor')
76 * Store useful information for later.
78 * @param DOMElement $element - this item as a DOM element
79 * @param XML_Feed_Parser_RSS1 $parent - the feed of which this is a member
81 function __construct(DOMElement $element, $parent, $xmlBase = '')
83 $this->model = $element;
84 $this->parent = $parent;
88 * If an rdf:about attribute is specified, return it as an ID
90 * There is no established way of showing an ID for an RSS1 entry. We will
91 * simulate it using the rdf:about attribute of the entry element. This cannot
92 * be relied upon for unique IDs but may prove useful.
94 * @return string|false
98 if ($this->model->attributes->getNamedItem('about')) {
99 return $this->model->attributes->getNamedItem('about')->nodeValue;
105 * How RSS1 should support for enclosures is not clear. For now we will return
110 function getEnclosure()
