Hello CHristian,

Thank you for help. Understood.

Structure <rest:response> was serialized to empty string. Now It is clear for me why data is lost.

Best Regards

If you change the return type of an XQuery function to xs:string, your nodes will be implicitly converted to strings.

This is the standard behavior of XQuery and no particular feature of RESTXQ. Play around with the query that I presented in my previous answer.

You need to remove the xs:string* return typeb you can replace it with item()*.
