And to make pmWiki generate a RSS? I have hacked pmwiki today 
(literally) to add this feature.

The idea is: to search in pagefile (in wiki-syntax) for chapter titles 
(^\!Something$). Each title become an item and the next line (if it is 
not a chapter title too) will be its description. To make a RSS from a 
page, the only thing is to call action=rss.

I have used the Feed Creator class, under GNU LGPL 
(http://www.bitfolge.de/rsscreator-en.html), added to local directory). 
Below, there is the function HandleRSS. To use it, it is necessary to 
add 'rss'= 'HandleRSS' to HandleActions hash.

function HandleRSS($pagename) {
  include "local/feedcreator.class.php";
  global $WikiTitle, $PageFileFmt, $ScriptUrl;
  $page = RetrieveAuthPage($pagename,"read");
  $rss = new UniversalFeedCreator();
  $rss->title = "$WikiTitle | $pagename";
  $rss->link = $ScriptUrl . "/" .  FmtPageName($PageFileFmt, $pagename);
  $rss->syndicationURL = "$rss->link?action=rss";
  if (!$page) Abort("?cannot source $pagename");
  $lines = explode("\n", $page["text"]);
  $count = 0;
  $descr = 0;
  foreach ($lines as $line) {
    if (preg_match("/^\!(.*)/", $line, $matches)) {
      if ($descr == 1) {
      $feed = new FeedItem();
      $feed->title = $matches[1];
      $feed->link = $rss->link . "#p" . ++$count;
     //It's not working. It's needed add <a name="pX" to every h1 in 

      $descr = 0;
    } else {
      if (($count > 0) && ($descr == 0)) {
        $feed->description = $line;
        $descr = 1;
  if ($descr == 1) {
  echo $rss->createFeed();

It is now in use at http://www.cyaneus.net. Most precisely at
