Question

I get this error from Saxon,

Engine name: Saxon-PE XQuery 9.2.1.2
Severity: fatal
Description: XQuery syntax error in #… (:return 🙂 let $#: expected “return”, found “let”
Start location: 776:0

on this function

declare function local:set-internet-type($req1 as element(ns0:req), $cate as element()) as xs:string {
  if(count(   for $itm in $req/*:cust/*:inter/*:itm
      where $789/*:product/*:030/*:specs/*:name/text()= data($11/INTERNET)
      and $22/*:action/text()="CHANGE"
      return $33)>0) then
  (
  for $44 in $55
      where $tt/*:name/text()= data($t/INTERNET)
   and $u/*:action/text()="CHANGE"
   (:return <fake/>:)

    let $z:= $a/*:product/*:c/*:e[1]

        return concat($x,'>',$y)
  ) else ("")
};

I am new with xquery and I spent a lot on this error without getting a solution. Vars were masked intentionally but from the error message seems something related to the function flow.

Any help is appreciated.

Thanks in advance

Saxon only declares to have “partial support of XQuery 1.1”. Therefore, I guess, it supports the old FLWOR format in which you cannot use let after where. Just try to swap these clauses:

for $44 in $55
let $z:= $a/*:product/*:c/*:e[1]
where $tt/*:name/text()= data($t/INTERNET)
   and $u/*:action/text()="CHANGE"
return concat($x,'>',$y)
