Sorry for the incomplete xml fragment, but those
bookmarks could be pretty much anywhere in hierarchy.

What did you want done with the ancestors of the ending bookmark?


An example is below using document order, but it will work with your example only because there are no ancestors of the ending bookmark that follow the starting bookmark. I can't guess what you want done with those ancestors.

I hope this helps.
