Hi,
I am extensively using a function wrapping xquery:eval. My use case is
roughly the following :
declare function local:eval_helper($exp,
$args){xquery:eval('$xml'||$exp,map{'$xml' := $args})};
declare variable $test := <toto><tata>1</tata></toto>;
local:eval_helper3('//tata', $test)
Since the following correction : [1]
https://github.com/BaseXdb/basex/issues/833, the previous code raises now a
[XPST0008] Undefined variable $xml.
I have tried several combinations to find a workaround, none are working :
- declare function local:eval_helper($exp,
$args){xquery:eval(''||$exp,map{'' := $args})};
([XPDY0050] Root of the context item must be a document node.).
- declare function local:eval_helper($exp, $args){xquery:evaluate($arg||$exp)};
[XPTY0019] Steps within a path expression must yield nodes; xs:integer
found.
-- declare variable $xml external := "xml", : [XPST0008] Undefined variable
$xml.
What is the correct workaround ?
Cheers
Jean-Marc
