Hi Dave,

The following XPath expression will return the direct ancestor of the
"note" element that is a "level2" element, or nothing, if the "note"
element does not have a "level2" direct ancestor:

$vNote/ancestor::*[starts-with(name(), 'level')][1][self::level2]

Do I understand correctly that by "direct ancestor" you mean the first
ancestor, whose name is levelX?
