Okay, if you can get parse_file to return a list of dictionaries like:
[
   {
    'folder':'whatever',
    'label':'whatever',
   }
]
...then you can do:

<span tal:define="opts 
python:here.lib.parse_file(file=here.news,sepr=',',clone=1)">
   <li repeat="opt opts">
     <a tal:content="python:opt/label"
        tal:attributes="href string:news_items/${opt/folder}"/>
   </li>
</span>

cheers,

Chris
