Can we write wiki pages into an RSS-Feed? Yes, we can. :-)
How can I build an RSS-Feed from my wiki pages?

Description

Creates RSS-Feed from wiki pages with pagelist directive

Notes

I needed that for our intranet. We needed a simple way for all users to see recent changes.

Installation

First of all put this in your local/config.php. You also can write it in an include file.

# change settings for RSS Feed
if((FmtPageName('$Group', $pagename) == "RSS") and ($Action != "edit")) 
	{  
	# Change HTML-Tags
	SDV($PageTextStartFmt, "\n\n");
	SDV($PageTextEndFmt, "\n");

	Markup('RSSP', '<<vspace>', '/<p.*?>/', '');
	Markup('RSSPEnd', '<<vspace>', '/<\/p>/', '');
	Markup('RSSCode', '<<vspace>', '/<code.*?>/', '');
	Markup('RSSCodeEnd', '<<vspace>', '/<\/code>/', '');

	# Change style path
	$Skin = 'rss';

	# simple markup for a counter
	$FmtPV['$RSSCounter'] = 0;
	function RSSCountup()
		{
		global $FmtPV;
		$FmtPV['$RSSCounter'] = $FmtPV['$RSSCounter']+1;
		return sprintf("RSS%04d", $FmtPV['$RSSCounter']);
		}
	Markup("rsscounter", 'directives', '/\(\:rsscount\:\)/e', 'Keep(RSSCountup())'); 

	# Enable XML Tags. Based on recipe enableHTML
	function RSSEnableXML($tag) 
		{
		Markup(
			"xml-$tag",
			'>{$var}',
			'/&lt;(\/?('.$tag.')(?![a-z!])(([\'"]).*?\4|.*?)*?)&gt;/ie',
			'Keep(PSS(\'<$1>\'))');
		}
	RSSEnableXML('item|title|description|link|author|guid|pubDate|b');
	}

Now you need a new template for that category in the folder rss.

<?xml version="1.0" encoding="iso-8859-1"?>
<rss version="2.0">
  <channel>
    <title>My own feed</title>
    <link>http://yourhost.com/rss.xml</link>
    <description>This are the recent changes.</description>
    <language>de-de</language>
    <copyright>Mr. Right</copyright>
    <pubDate></pubDate>
    <image>
      <url>$SkinDirUrl/my_logo.gif</url>
      <title>My own feed</title>
      <link>http://yourhost.com/rss.xml</link>
    </image>
	<!--PageText-->
  </channel>
</rss>

I used iso-8859-1 and language de-de for german umlauts. You can change it.
For more Details on RSS look in to wikipedia. :-)

Now you create a startpage/homepage for that category with a pagelist for the last recent changes.

(:if false:)(:nolinkwikiwords:) 
[[#rss]]
(:template each:)<item>\
	<title>{=$Title}</title>\
	<description></description>\
	<link>http://yourhost.com{=$PageUrl}</link>\
	<author>{=$LastModifiedBy}</author>\
	<guid>(:rsscount:)</guid>\
	<pubDate>{=$LastModified}</pubDate>\
</item>
[[#rssend]]
(:if:)

(:pagelist trail=Site.AllRecentChanges group=-Category,-Templates count=-10 order=time wrap=inline fmt=#rss:)
