These are the MediaWiki extensions we're using and/or developing. Please refer to the information on the mediawiki.org wiki for installation and usage details. Extensions here which have no corresponding mediawiki article are either not ready for use or have been superseded. You can also browse our extension code in our local Subversion repository or our GitHub mirror.

$wgRobsRSSTag = "rss"; $wgRSSUseAjax = false; $wgExtensionFunctions[] = 'wfSetupRobsRSS'; $wgExtensionCredits['parserhook'][] = array(

       'name'        => 'RobsRSS',

1. Called from $wgExtensionFunctions array when initialising extensions

function wfSetupRobsRSS() {

       global $wgParser,$wgRSSUseAjax,$wgAjaxExportList,$wgRobsRSSTag;
       $wgParser->setHook($wgRobsRSSTag,'wfRssTagHook');
       if ($wgRSSUseAjax) $wgAjaxExportList[] = 'wfRenderRSS'; # Allow Ajax Dispatcher to call wfRenderRSS
       }

1. Expand an <rss> tag

function wfRssTagHook($text,$argv,&$parser) {

       global $wgRSSUseAjax;
       $args = ;

foreach ($argv as $k => $v) $args .= "

$k: $v

\n";

       if ($wgRSSUseAjax) {
               # Render a container which does ajax requests for content

$html = "

an ajax thingie

";

               }
       else {
               # Not using ajax, render the output now
               $html = wfRenderRSS($data,$timestamp);
               }
       # grab each url and process
       $data = wfReadRSS(preg_split("/[\n\r]/", $text, -1, PREG_SPLIT_NO_EMPTY));

       # dump data        

foreach ($data as $k => $v) $html .= "

$k: $v

\n";

       return $html;
       }

1. Render a portion of RSS data (which is in the useful format returned by wfReadRSS)

function wfRenderRSS($data,$timestamp = false) {

       return $html;
       }

1. Read RSS from URL's and return as some kind of useful runtime structure

function wfReadRSS($urls) {

       $data = array();
       foreach ($urls as $url) {
               $doc = new DOMDocument();
               # do some cache stuff here
               $doc->load($url);
               # get feed details
               $feed=$doc->getElementsByTagName('channel')->item(0);
       $feed_title = $feed->getElementsByTagName('title')
       ->item(0)->childNodes->item(0)->nodeValue;
       $feed_link = $feed->getElementsByTagName('link')
       ->item(0)->childNodes->item(0)->nodeValue;
       $feed_desc = $feed->getElementsByTagName('description')
       ->item(0)->childNodes->item(0)->nodeValue;
               $data[] = $feed;

/* foreach ($doc->getElementsByTagName('item') as $item) {

               # what follows looks overly complicated? simplify?
               $item_title=$item->getElementsByTagName('title')->nodeValue;
               $item_link=$doc->item($i)->getElementsByTagName('link')
               ->item(0)->childNodes->item(0)->nodeValue;
               $item_desc=$doc->item($i)->getElementsByTagName('description')
               ->item(0)->childNodes->item(0)->nodeValue;
               $item_date=$doc->item($i)->getElementsByTagName('pubDate')
               ->item(0)->childNodes->item(0)->nodeValue;
               # <pubDate>Tue, 20 May 2003 08:56:02 GMT</pubDate> 

$data[] = "

$item_title: $item_link $item_desc $item_date"; # add collected info into $data # TODO need to grab date information so we can sort # Date is in UDF from memory }*/ } return $data; } ?>
