Ok here It Is :
1 - the creation of a RSS feed page: "PersonalRSS" in space " Main"
with
code :
$response.setContentType("text/xml")
#set($baseurl = "http://${request.serverName}")
#set($member = $request.uid)
#set($title = "$member.replace('XWiki.','') Personal")
#set($description = "Flux RSS Personal of
$member.replace('XWiki.','')")
#includeForm("XWiki.PersonalRssCode")
2 - the creation of the RSS Code page: "PersonalRssCode" in space Xwiki
with code :
{pre}
#if($member=="")
#set($member="XWiki.XWikiGuest")
#end
#set($memberdoc = $xwiki.getDocument($member))
#set($cobj = $memberdoc.getObject("XWiki.XWikiUsers"))
#set($personalrss = $memberdoc.display("blogfeed","view",$cobj))
#set($personalrss = $personalrss.replace("@","','"))
#set($sql = "where doc.fullName in ('${personalrss}') order by doc.date
desc")
#set($list = $xwiki.searchDocuments($sql ,0, 0))
#set($rsvc= $xwiki.xWiki.getRightService())

{/pre}
3 - the creation of the page which add and remove chosen pages :
"EditPersonalRSS" in space "Xwiki" with code :
#if($request.page)
#set($newrsspage = "(a)${request.page}")
####### on cherche la liste
#set($member = $context.getUser())
#set($memberdoc = $xwiki.getDocument($member))
#set($cobj = $memberdoc.getObject("XWiki.XWikiUsers"))
####### on recupere les pages existantes
#set($oldrsspages = $memberdoc.display("blogfeed","view",$cobj))
######################################################################
#if($request.action == "add")
####### on injecte la nouvelle
#if($oldrsspages == "")
#set($oldrsspages = "$newrsspage")
#else
#set($oldrsspages = "${newrsspage}${oldrsspages}")
#end
######################################################################
#elseif($request.action == "sub")
####### on enleve la page choisie
#set($oldrsspages = $oldrsspages.replace("${newrsspage}","")))
######################################################################
#end
####### on sauve
$memberdoc.use("XWiki.XWikiUsers")
$memberdoc.set("blogfeed",$oldrsspages)
$memberdoc.save()
####### on redirige
#$response.sendRedirect($xwiki.getURL(${request.page}))
#else
#$response.sendRedirect($xwiki.getURL("Main.WebHome"))
#end
4 - Implement the links to this Personal RSS Feed
The link to create the RSS Feed:
<a href="$xwiki.getURL("Main.PersonalRSS", "view",
"uid=${context.user}&xpage=rdf")")">Personal RSS <img
src="$xwiki.getSkinFile("icons/black-rss-mini.png")"></a>
And in the pages you want to be followed (you can add this code in the
"view.vm" page for example):
#set($mdoc = $xwiki.getDocument(${context.user}))
#set($cobj = $mdoc.getObject("XWiki.XWikiUsers"))
#set($prss = $mdoc.display("blogfeed","view",$cobj))
#if($prss.contains(${doc.fullName}))
<a
href="$xwiki.getURL("XWiki.EditPersonalRSS","view","page=${doc.fullName}
&action=sub")">Unfollow This Page</a>
#else
<a
href="$xwiki.getURL("XWiki.EditPersonalRSS","view","page=${doc.fullName}
&action=add")">Follow This Page with RSS</a>
#end
5 - Problems encountered
- I'm using the field "blogfeed", the best is to create a new
property in the Object XWiki.XWikiUsers
- Everybody can follow the Personal RSS Feed of everybody just
by adding the Feed with a "Xwiki.login_of_user" instead of the
"${context.user}"
That's work fine, but I think it is possible to ameliorate my code.
