Just a very basic question. I don't understand. $pn is a "default
argument" of PageVar function ?
The code defined for $FmtPV is in quotes, because it will be evaluated
in PageVar(). When that happens, there are a few variables that are
available directly in your code: $pagename, $pn, $group, $name, $page.
$pagename is the page currently requested for browsing, and $pn is
either the same, or some remote page where you need to get the $Title,
or some $:PTV. $page is the full page metadata (text, author, dates, ip
address, etc.). Here I'll use $pn because I'll have to get information
from different pages.
In our case, when a variable {$TitreArticle} is requested, it will be
evaluated inside PageVar() and that code will call once again PageVar()
but with a different argument, for the page text variable.
Now that I think of it, it can be optimized to directly call
PageTextVar:
$FmtPV['$TitreArticle'] = 'PageTextVar($pn, "TitreArticle")';
This should be slightly faster than my first line but not noticeably --
maybe a few microseconds. I'm sure the time I spent writing this change
you reading it will only be saved in several hundred years. ;-)

Sorry for the late reply.
This should work, where {$:TitreArticle} is your PTV :
$FmtPV['$TitreArticle'] = 'PageVar($pn, "$:TitreArticle")';
$FeedFmt['rss']['item']['title'] = '{$TitreArticle}';
You don't need to use ResolvePageName() like you wrote in the French
mailing list, in fact you should probably remove it.

Hello everybody !
Do you think it is possible to insert a page text variable in a RSS
feed ?
I saw that it is possible with page variables, like this :
$FeedFmt['rss']['item']['title'] = '{$Title}';
But I would like to have something like that :
$FeedFmt['rss']['item']['title'] = '{$:var}';
So I tried to create a php variable with this :
$var=PageVar($pagename [1],'$:var')
But this code doesn't work.
$FeedFmt['rss']['item']['title'] = '{$var}';
Nothing in "output feed" (sorry for my awful english !).
Someone have an idea ?
