As you might be able to guess from the name, selectSingleNode()
selects a single node -- you can't get *all* the ancestors that way.
Instead, you need to use selectNodes(), which will return a NodeList.

It would really help us to help you if you posted the code that you're
trying to use. Presumably you've tried something like:

  cat = doc.selectSingleNode("//cat[@id = '" + catid + "']");
  ancestors = cat.selectNodes("ancestor::cat");
