[xquery-talk] Update bug?

[Leo Studer]

Hello

I am using Oxygen 17.0 with Saxon EE 9.6.0.5 as the xQuery Update processor.

I want to move an attribute one level deeper.

In the example I want to move att="att” from <a> to <b>

<?xml version="1.0" encoding="UTF-8"?>
<a att="att">
    <b/>
</a>

Here my code:

delete node doc("xml.xml")//@att,
insert node doc("xml.xml")//@att into doc("xml.xml")//b

Each of these two statements work correctly alone but when I try both together I get java.lang.NullPointerException.

Can anyone explain what happens here?

Thanks in advance
Leo
