[pmwiki-users] How to export (:pagelist ...:) to a file e.g text/plain

Dear PmWiki Users,

As adviced by Peter I have tried to use RunMarkupRules() of toolbox.php
with no success. Probably I am not something obvious in the deep level
of PmWiki structure.

Below you will find what I have done with a minimal example. In the
action function (i.e HandleExport) I have tried both Peter's advice and
also tried just to dump the parsed HTML output. In Peter's advice,
"$Text" was empty; in MarkupToHTML I have received only "<" (1 byte).

In short, I couldn't manage to fill $Text with (:pagelist...:) parsed
and converted to #csv format.

As I said, probably I am missing something obvious. Any idea to fix it?

Thanks in advance.

        if (!$page) HandleBrowse($pagename, $auth);

        # Collect the content
        $Text = $page['text'];
#       $output = RunMarkupRules($pagename, array('pagelist'), $Text, $opt);
#       $output = MarkupToHTML($pagename, $Text);

        # Dump back to page
        if ($output != '')
                $fname = FmtPageName('$Name',$pagename).'.txt';
                header('Content-Type: application/download');
                header('Content-Disposition: attachment; filename="'.$fname.'"');
                header("Content-Length: " . sizeof($output));
                echo $output;
                HandleBrowse($pagename, $auth);
