I use ancestor-or-self::* to obtain the node sequence from some node to the document root. The outermost/top element of the document isn't interesting, so I add a predicate, and I find that this works: [position() != last()] Apparently, the sequence goes from leaf to root, which is the closing tag order, as it should be. It has nothing to do with iteration/for-each I think, XPath 2.0 when defining a step in a path expression that returns a sequence of nodes says the following: "If every evaluation of E2 returns a (possibly empty) sequence of nodes, these sequences are combined, and duplicate nodes are eliminated based on node identity. The resulting node sequence is returned in document order." Thus if you have E1/ancestor::* ancestor::* returns a sequence of nodes but for the result of the expression duplicates are eliminated and nodes are ordered in document order. -- Martin Honnen http://msmvps.com/blogs/martin_honnen/
