[xquery-talk] XQuery Update: replacing element content with a sequence of nodes

[Jonathan Robie]

What assumptions can you make about the possible content of that element?

The target of replace needs to be a single node. If the element can 
contain multiple nodes, or none, and you don't know in advance, you may 
be better off deleting the children of the parent element, then 
inserting your content.

In a real application, what you insert may depend on the original 
content, of course, so you might test what's there and respond 
appropriately.
