Many thanks. I appreciate the help. I think I've incorporated your 
suggestion into the code below...

<html>
   <body>
     <span
tal:define="opts 
python:here.parse_file(file=getattr(context,options.parm),sepr=',',clone=1)"> 
       <tal:block repeat="opt opts">
          <li><a     tal:content="python:opt[1]"
               tal:attributes="href python:opt[0]"></a></li>
       </tal:block>
     </span>
   </body>
</html>

Unfortunately, when I try to use this expression

<dtml-var expr="testlist(parm='links')">

I get this Zope error:-

Error Type: AttributeError
Error Value: 'dict' object has no attribute 'parm'

Can't help thinking it is a simple syntax error - missing bracker, quote 
etc... but just can't figure it out.
