You're absolutely right that the ancestor axis is a reverse axis. If
you were using:
ancestor::*[1]/@attr
you'd be fine (aside from the fact that you'd be stuffed if the node's
parent didn't have a 'attr' attribute). However, the last axis used in
the XPath is the 'attribute' axis, which takes you back to document
order again. To get the last one, use:
ancestor::*/@attr[last()]
At least I *think* that's right ;)
