[basex-talk] the implicit context of position

Hello -- I've got an element node that's part of a document. I need its position among the element children of its parent. $step/position() will (correctly!) always return 1, there's one thing in $step, of course it does. replace($step/path(),'^.*\[(\p{Nd}+)\]$','$1') => xs:integer() gets me the implicit position but is something of a horror. for $e at $in in $step/../* where $e is $step return $in works, too, but any notion of elegance and clarity have fled screaming into the night. I keep thinking there must be a better way; anyone got any suggestions? Thanks! Graydon
