you forgot to add the generate-id + a newly created node to add to the
URI. However, the processors you mention use XSLT 1.0. To get the same
behavior in XSLT 1.0 you need to be a little bit more creative and use
the extension function exslt:node-set (or equivalent for your
processor).


I felt creative enough calling an external script, so I forgot to be
more creative :-) Now, following your example: This works for Saxon
(both 6.5.5 and 9.0.0.4) and for Xalan-J 2.7.1, but not for Xalan-C
1.10.0 and LibXSLT 1.1.22. The latter do not seem to generate new nodes,
so no new IDs are generated either.

Interesting... :)

What you might try is using a "real" node (I mean, an element). Any node is "real" of course, but perhaps Xalan-C (I'm surprised it doesn't show the same behavior as Xalan-J) and LibXslt are more inclined to do the effort to create a new node when the node itself is an element.

One might argue that this is a non-conformance bug, but I vaguely remember having had a discussion along these lines with Michael Kay. The net result of that discussion being that node-set is an extension function and once an extension function (or instruction) is in place, all bets are off considering conformant behavior.

That said, if you state "node-set creates a node or a set of nodes" and "generate-id generates a unique id for each node" would mean, imho, that the mentioned behavior is indeed a bug (though perhaps not strictly non-conforming).

Btw1, what about *not* using node-set? Would generate-id work on the $node variable? Would it work in the same way? Btw2, does any of these processors have an extension instruction, like Saxon, to create a node from a string representation of XML? if so, would that yield the same erroneous results?
