Thank you Bruce, My colleague began to have some approval of dealing a step (regardless of how many predicates attached) as a whole, //rec/(para[1]). That is a big progress for me. We are following the XPath 2.0 spec. Are the both have the same behaviour about the parsing of steps with predicates?
Frankly, I haven't spent much time looking at the XPath 2 spec, since I would be wishing for features I can't use in my current applications...
While we still cannot reach an agreement about the DFS and BFS dispute. For example, step1/step2/step3/step4, assume that each has multiple matched nodes, should it be interpreted as step1/(step2/(step3/step4)) or ((step1/step2)/step3)/step4?
Either, depending on what you mean by the parentheses :> You might try the XPath 1 spec as (possibly) being shorter and easier to digest; especially section 2 about Location Paths: "The initial sequence of steps selects a set of nodes relative to a context node. Each node in that set is used as a context node for the following step. The sets of nodes identified by that step are unioned together." Hope that helps; bruce
