Dear BaseX team, version 3.0 of the XQuery Update Facility (XQUF) allows expressions to perform an updating operation *and* return a value (e.g. [1]). Presently, BaseX supports probably only version 1.0 of the XQUF, so the mixing of update and value creates an error - and option MIXUPDATES equal "true" does not change this.: Query:=============================== declare option db:mixupdates 'true';
100, insert node <elem/> into * ================================>Stopped at C:/projects/act/updateQuery.xq, 5/1: [XUST0001] List expression: all expressions must be updating or return an empty sequence. In my opinion, the possibility to mix updating and value construction is very important, as otherwise it is impossible to develop versatile tools which may, dependent on call parameters, either return a result or perform an update. So my Q U E S T I O N is - are there already plans to support XQUF 3.0 - or as a first step the mixing of update and value - soon? Would be phantastic! Cheers,Hans-Jürgen [1] http://www.w3.org/TR/xquery-update-30/#id-comma-expr"The operand expressions of the comma expression are evaluated,and the XDMinstances and pending update lists returned areconcatenated in operand order. Pending update lists are concatenatedby the upd:mergeUpdates operation."
