xpath finding cousins

Ah--

Then I can find the interrupting <civil-event title="d"> by the xpath
statement "following::*[name()
=$element][1]/preceding-sibling::civil-event".  But if the <civil-event
title="d"> takes up the whole class (or, in other words is the only child
of <document>) as it does in the first XML sample, then this xpath
statement doesn't work.

Right -- because in that case, it's not a preceding sibling of the <war> element you've found in the first step of the path.


Changing the XPath to be a bit more general, as in

following::*[name()=$element][1]/preceding::civil-event[1]

will find it, and is in keeping with the kind of traversals you're already doing.

  It seems I can find everything but this situation.
This is what I need help with.

That XPath should match either case.


But this is pretty funky stuff -- I'm not sure I like either the processing methodology or the design of the tag set very much -- but if it's working so far, then go for it. You can refactor it all later, once it's stabilized a bit.

Cheers,
Wendell
