15989 2007-11-14 12:41:07 -0800 XPath queries with predicates incorrectly retains the current node across unions 2007-11-15 22:04:59 -0800 1 1 1 Unclassified WebKit XML 523.x (Safari 3) Mac OS X 10.4 RESOLVED FIXED P2 Normal --- 1 khooyp ap ap oldest_to_newest 61229 0 khooyp 2007-11-14 12:41:07 -0800 In the nightlies as well as Safari 3.0.3 on Tiger, XPath queries which contain unions of queries with predicates (e.g. "ancestor::xhtml:*[local-name()='span']|.") doesn't quite work right. It seems that the context-node gets overwritten by each union operand predicate, so every subsequent operand is applied to the wrong context node. E.g.: <div> <span id="A"> <span id="B"/> </span> </div> The query "ancestor::xhtml:*[local-name()='span']|." from span#B will not return [span#A, span#B] since the context-node for both operands are span#B. It will instead return [span#A, div], as if the context-node for the second operand had been the top-most ancestor. 61230 1 17276 khooyp 2007-11-14 12:42:19 -0800 Created attachment 17276 Test case in XHTML and inline Javascript. 61321 2 17300 ap 2007-11-15 12:28:09 -0800 Created attachment 17300 proposed fix This makes me think that we might need to import another large XPath test suite. Unfortunately, the only ones I know are XSLT-based, and would require a lot of work to adapt. I've tried to think of other places where we need to restore the context, but I don't see any. 61331 3 17300 darin 2007-11-15 13:29:41 -0800 Comment on attachment 17300 proposed fix r=me \ No newline
