whatcha gonna end up doing is writing a loop to output your list; a
simple XPATH query in the DOMDocument ain't gonna produce the list (I
could be wrong here, I'm not an XPATH guru)

Have you tried:
Set oIDList = oDOM.SelectNodes("/bobtypes/bob")
if oIDList is Nothing then
  ' nothing there, do whateever you must
  ids = ""
else
  For each oID in oIDList
    ids = ids & oID.getAttribute("id") & ","
  Next
  ' hack the trailing comma
  ids = left(ids,len(ids)-1)
end if

(or something similar to the above, it was off the top of my head)

I've poked around the MS XML docs, and their XPATH stuff is
XSLT-focused, but there are some gems to get out of it:

Now, there may be a way with XPATH to enumerate the attributes with
the DOMDocument, but I've not spent the time looking, maybe the
secret is in the SDK somewhere....

Hope that helps
