Is there a way to do something like this?

declare function local:insert(

$doc as node(),

$at-location as xpath(), (: I know, there is no 'xpath' type, this is just for demo :)

$what as node()*

) as node() {

copy $c := $doc

modify insert node $what into $at-location

return $c

};

let $xml := <xml><body><p>This is a paragraph.</p></body></xml>

let $nd := <this><is><a>Test</a></is></this>

return local:insert($xml, xpath("/body"), $nd)

As I see it, it would need a dynamic xs:string => XPath expression conversion or a defer XPath expression, which both do not exist, for $at-location. I managed to do this, however:

declare function local:insert($doc, $at-location, $what) {

let $update := ``[

declare variable $doc external;

declare variable $what external;

declare variable $at-location external;

copy $c := $doc

modify insert node $what into `{$at-location}`

return $c

]``

return xquery:eval($update, map{

'doc':$doc,

'at-location':$at-location,

'$what':$what

})

};

let $xml := <xml><body><p>This is a paragraph.</p></body></xml>

let $node := <this><is><a>Test</a></is></this>

return local:insert($xml, "$c/body", $node)

Ideally (for me), there would be a 'defer' XPath expression, that starts its life as a string (when passed) and then unfolds upon call. Or a type (or function) fn:xpath(), that behaves that way.

Or am I just blind and don't see the obvious, and there is a simpler solution?
