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
