I am trying to use xquery replace but cannot, it seems, figure out the correct syntax. As I understand it, the replace query should be of the form: "xquery replace expr with node", so I'm trying to do the following:
xquery replace root()/child with <child>new data</child>
Stopped at line 1, column 15: Syntax: XQUERY [query] Evaluate XQuery.
I've tried a number of variations but I get the same error. Any ideas? Thanks.

Also, is the 'replace' operation atomic?

Hi Travis,
all xquery operations are atomic.
If you want to replace the value of the node you have to write the query as following:
-> xquery replace value of node root()/child with "new data"
I hope this helps, as first advice.

Ok, thanks for the quick response. I wanted to make sure repalce wasn't just an insert/remove sequence which would make it unatomic.
How would I replace the node with a completely new one? So if I didn't want to just replace the 'value of', how would I do that?

…just omit the "value of" keywords; find more at e.g.
