xdmp:node-insert-child

xdmp:node-insert-child(
   $parent as node(),
   $new as node()
) as empty-sequence()

Summary

Adds a new last child to a node. For XML documents, only element nodes and document nodes can have children. For JSON documents, object nodes and array nodes can have children. Element nodes, object nodes, and array nodes cannot have document node children. Document nodes cannot have multiple roots. On-the-fly constructed nodes cannot be updated. The parameters must specify individual nodes and not node sets.

Example

(: create a document :)
xdmp:document-insert("/example.xml",
    <a/>);

(: insert a child of a :)
xdmp:node-insert-child(doc("/example.xml")/a,
    <b>bbb</b>);

(: look at the new document :)
fn:doc("/example.xml")
 =>
<?xml version="1.0" encoding="UTF-8"?>
<a><b>bbb</b></a>
