Ok here It Is :

$response.setContentType("text/xml")
#set($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")

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())

3 –
the creation of the page which add and remove chosen pages : “EditPersonalRSS”
in space “Xwiki” with code :
#if($request.page)
#set($newrsspage =
"@${request.page}")
####### on cherche la liste
#set($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

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

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.
