Are you missing the fact that position() can be used during apply-templates processing, in the same way as during for-each processing?

But this has a catch, since index-of still requires the construction of the overall sequence using an XPath expression. But (and this is, for me, the catch) that the selection of the nodes that will eventually be processed depends on attribute values of template+@match and/or apply-templates+@select. This means that you need two ways to produce the same sequence of nodes for index-of to work. (I do know that XPath is powerful enough. so it's not an issue of not being able to - it's just duplicating an effort.) > > A function like fn:nth-time-around() in the context of a template would take care of the problem, which (apparently) isn't frequent enough to warrant such a function. > > Perhaps I'm simply ignorant of something? > -W > > XSL-List info and archive > EasyUnsubscribe (by email)
