When you use the name() function on a node set, it tells you the name
of the *first* node in that node set (in document order). So:

  name(ancestor::*)

will always give you the name of the document element in your XML
document.

Instead, you need to go through all the ancestor elements one by one
and filter in those whose name contains the string 'region' using a
predicate:

  ancestor::*[contains(name(), 'region')]

This will return a node set containing all the ancestors whose name
contains the string 'region'. If there are nodes in that node set,
then it evaluates as true, if not, it evaluates as false.

I hope that helps,

Jeni
