Hello BaseX team !
I lost some time to detect an error in my code, and wonder if there is a minor bug into the BaseX compiler. Here is the test
let $elt as element(*)*:= <universe id="yolo"></universe> for $d in (1 to 1) return let $idd := $elt[d]/@id return ($elt[$d]/@id,$idd)
output : id="yolo".
(Hence missing the second "yolo", because the correct query is : let $idd := $elt[$d]/@id)
However I can't figure out why the BaseX compiler ran this query ? Shouldn't it refused the compilation and point out this error ?
Cheers,
Jean-Marc
Dear Jean-Marc,
let $idd := $elt[d]/@id
Shouldn’t it be '$d' instead of 'd' ?
let $idd := $elt[$d]/@id
Cheers, Christian
return ($elt[$d]/@id,$idd)
output : id="yolo".
(Hence missing the second "yolo", because the correct query is : let $idd := $elt[$d]/@id)
However I can't figure out why the BaseX compiler ran this query ? Shouldn't it refused the compilation and point out this error ?

Hello Christian,
Yes. But my question is : why did the BaseX compiler ran the query let $idd := $elt[d]/@id ? Shouldn't it raise a compilation error ?

Yes. But my question is : why did the BaseX compiler ran the query let $idd := $elt[d]/@id ?
The query is valid, because $elt could have an element named d. For example, the following query returns the value of $elt:
let $elt := <u><d/></u> return $elt[d]
Does this help? Christian
Shouldn't it raise a compilation error ?
