This would be hard for a scriptlet to handle, since it would have to
fetch a separate document into a hidden window or frame. It would
be easier for a scriptlet to extract *all* of the relevant link tags and
then pass those on to the underlying site as an argument list. The
site can then present a web-based UI to allow the user to choose
any or all of the feeds.

For example, here's a scriptlet that I found:

oid(d=document);
void(el=d.getElementsByTagName('link'));
for(i=0;i<el.length;i++)
{
  if(el[i].getAttribute('rel').indexOf('alternate') != -1 && el[i].getAttribute('type').indexOf('text/xml')!=-1)
  {
    void(location.href='http://www.syndic8.com/feedinfo.php?FeedDataURL='+el[i].getAttribute('href'))
  };
};

It would not be hard to modify it to accumulate all of the tags and then pass
all of them to the site.
