===== Applying wiki formatting to imported text =====

So I've been working the past couple of days trying to do someting Dokuwiki wasn't originally designed to do - import live data and apply wiki formatting.  I've looked at about every possible plugin to get external data in, but none of them will render wiki syntax.  Here is a snippet from the syntax.php (I added a new case for the oext section around line 200):
<code>
          ...
          switch ($config[$mode]['oext'])
            {
            case 'wik' :
              $myinfo = null;
              $myrev = null;
              $myid = null;
              $renderer->doc .= p_render('xhtml',p_get_instructions(io_readWikiPage(&$OutFileName,$myid,$myrev)),$myinfo);
              break;

            case 'out' :
              $renderer->doc .= "<pre>$output</pre>";
              break;
            ...
</code>
Here is the section of my default.php I am using for getting wiki-code text from a wget link:
<code>
$conf['importwikitext']=  array('name'    => 'Import Dokuwiki-formatted text',
    'xhtml' => array('iext'    => 'tmp',
                     'oext'    => 'wik',
                     'pre'     => "",
                     'post'    => "",
                     'command_wintel' => '', 
                     'command' => '/usr/bin/wget -O - -i @InputFile@ 2>/dev/null'));
</code>
And here is my dokuwiki page code:
<code>
~~NOCACHE~~
<chain alias=importwikitext output=wikitext render=yes>
http://<webserver>/<url>
</chain>
