Re: [basex-talk] BaseX 9.3: The Winter Edition; {position()>1] vs. [./position()>1
you are absolutely right - the old the old basex version (9,2,4) considered both statements as equal. This means - the issue was in 9.2.4 and is fixed in 9.3 ... sometimes existing code makes existing bugs accessible as features thanks in advance alex Am 02.12.2019 um 21:07 schrieb Christian Grün: Hi Alex, Could you share a little self-contained example with us that demonstrates the wrong behavior, and name the versions of BaseX you tested? The two following expressions are equivalent: //row[position() > 1] /descendant-or-self::node()/child::row[position() > 1] They are not equivalent to: //row[./position() > 1] /descendant-or-self::node()/child::row[./position() > 1] Each result of child::row will be bound one by one to the context item in the predicate, thus ./position() will always yield 1. You can run the following queries to see the difference: (,)[trace(position())], (,)[trace(./position())] Does this help?
