Re: get immediat preceeding node, if it is a comment

You can have any number of  predicates in a step and after each one the remaining nodes in the current node list are those nodes for which the predicate was true. while evaluating the next  position() and last() and count() all refer to the current node list (ie the list of nodes that have survivied any previous  predicates in the step) > preceding-sibling::node()[normalize-space()][self::comment()] > > this gets 'test1' and 'test3' as we would expect anything that involves  (anywhere) will select a node set of at most one node. Your description in english suggests you used the expression */preceding-sibling::node()[normalize-space()][self::comment()] while <root> is your current node. ie find all children that have the stated condition. > So is it the case that all predicates to the right of the positional > predicate refer to that node? (they change the context node) Yes but there is nothing special about the positional predicate it is just shorthand for the boolean test [position()=1]. All later predicates refer to nodes for which earlier predicates are true.
