One way you might solve this problem is to create a new result that combines
the original results with the new results. You can then save the new result as
the final step. The code below shows how this could be done. The input
parameter contains the node that will be inserted into the <results/> node.
------------------------------
xquery version "1.0-ml";
declare function local:updatenodes($insertnode)
{
let $uri := "/test.xml"
let $original := fn:doc($uri)
let $results :=
if(fn:exists($original)) then
(: Use the original results - note that we need the first element node :)
$original/element()
else
(: Create some initial results :)
<results foo="bar" bar="baz"/>
(: Add some information to the results :)
let $modifiedResults :=
(: Use a computed constructor - dynamically get the node name to avoid hard
coding :)
element {fn:node-name($results)}
{
(: Add back the original attribute nodes :)
$results/@*,
(: Add back the original child nodes :)
$results//*,
(: Add the new results :)
$insertnode
}
(: Save the newly created node to the database using the same uri name :)
let $save := xdmp:document-insert($uri, $modifiedResults)
return $modifiedResults
};
let $insert := <oneResult a="b"/>
return local:updatenodes($insert)
-----------------------------------------
Note that this function can only be called once for a given transaction. If
you need to make more than one modification, then you might need to modify the
function to make all of the changes at once.
Hope this helps.
