Subject: Re: XPath optional node question From: David Carlisle <davidc@xxxxxxxxx> Date: Mon, 4 Dec 2000 18:56:08 GMT |
me> bar[ancestor::foo and ancester::*[self::foo or descendent::foo or me> self::a or self::b]] PS the xpath I just posted doesn't deal with the most general case (it will be confused if bar has foo descendents, eg foo/x/bar/foo would be accepted as the x is an ancestor of a foo, so not barred. I'm not sure it is possible just uing xpath, in full generality. If you can use xslt rather than just xpath it's usually easier to recurse down the tree checking the constraints as you go rather than trying to construct a majic xpath to do it all in one go.
