[Zope] How to pass a list of 2 values each to dtml

Hia Zopistas, I have a form that prints out links with checkboxes. I want to pass the checked links to a dtml-method. the form looks like <input type="checkbox" name="urllist:list" value=" [url goes here] || [linkname goes here]"><a href ..... [and here goes the link itself </a> this is printed out for every link. Now I want to call a method foo(url, name) how can I split the passed strings in urllist into 2 parts and assign them to variables in dtml I can pass to foo ? or is there a way to pass a tuple or list in the form directly?
