Good, that's what I initially expected. > What exactly in the draft led you to think otherwise? My interpretation is as follows: "foo" selects the foo children of the current node For each of these, "//" selects its descendants "bar" filters these to select the bar descendants The predicate "[5]" is evaluated "with the complete list of nodes to be filtered as the context node list" (6.1.3) - ie, all the bar descendants of the current foo node. "5" is equivalent to "position()=5", and "position()" returns the position of the node in the context node list (6.2.2). So it selects the fifth of all the bar descendants. This is not what I said in my previous message - I was wrongly taking the context list to be all the bar descendants of all the foo children, rather than evaluating //bar[5] separately for each foo. But it's still not what you say above. And an example in section 6.1 seems to confirm my (revised) interpretation: /from-descendants(figure[position()=42]) selects the forty-second figure element in the document It doesn't say "selects any figure element that is the 42nd child of its parent".
