Re: ancestor axis order
with the expression ancestor::*[self::define or self::choice][self::choice] there are no 'nested' predicates, hence its a single step. I.e. the step is all in reverse document order. I'm not sure what you mean by a nested predicate but yes,, it's a single step because XPath steps are the chunks you get by splitting up an expression at top level / /a[a/b/c]/x/y[a or b or c/d] has three steps /a[a/b/c] /x /y[a or b or c/d] although of course the sub-expressions such as a/b/c are themseleves made up of multiple steps. Innermost being the node closest to 'ref' element, further away from the root. yes (sorry one place I lapsed iinto ad-hoc terminology rather than xpath terminology) David -- The LaTeX Companion http://www.awprofessional.com/bookstore/product.asp?isbn=0201362996 http://www.amazon.co.uk/exec/obidos/tg/detail/-/0201362996/202-7257897-0619804 ________________________________________________________________________ This e-mail has been scanned for all viruses by Star Internet.
