getting all parent elements for breadcrumb nav

Hi all and happy holidays!

I am working on an application that uses the xbel dtd
for a set of bookmarks. In the xslt I am writing, I
want to create a breadcrumb navigation item at the top
so that the user can walk up and down the folders. I
pass in a folderID in the xml so that I can show the
proper folder and need to somehow grab all of that
folder's parent elements and put them into a
breadcrumb navigation line (Top folder > sub folder >
sub folder).

Any ideas on how to do this? Seems to me it will
require a named template, but I can't quite seem to
wrap my head around it.

Thanks in advance for the help! Here are the xml and
xslt:
