Hi Christian,
thanks for clarifying this. To be sure I got this right: The xquery passed to basex:eval() has to be self-contained, no way to refer to anything that's not literally passed to the function?
Regards,
Maxi

Dear Max,
in BaseX, the eval() function ignores the existing context. This decision was taken to simplify numerous optimizations. As an example, in the following query, local:n() will be inlined as removed by the dead code detector:
declare function local:n() { 1 }; local:n()
Some code optimizations could be suppressed if eval() functions are encountered in the query. This is subject to further work, though.
Sorry; hope this helps anyway, Christian

Hi there,
I am using basex 6.2.7 (gui version) from the maven repo.
Using eval (see below) gives me: Fehler: [XPST0017] Unknown function "local:name1(...)".
If I call local:name1() directly, it works. Running the same script with Saxon (using saxon:evaluate) works, too.
declare function local:name1() { let $msg := "hello from name1" return <msg>{$msg}</msg> };
declare function local:dispatch($e as element()) { let $func := local-name($e) let $res := basex:eval(concat("local:", $func, "()")) return $res };
let $elem := <name1>bla</name1> (: return local:name1() :) return local:dispatch($elem)
