XQuery Update

[nikolayo]

Hi,

Saxon-SA (included in oXygen 10) already supports XQuery Update.
Is oXygen going to support it too? When?

The support for XQuery Update is scheduled for one of the minor releases of the actual version 10.

It would be great if this was enabled in oXygen soon.

Thanks!

Thank you very much for implementing XQuery Update support in 10.3.
Transform expressions ("copy - modify")do not seem to work. They
always fail with a message saying that node is not modifiable. Would
you mind telling us whether this is a "feature" of Saxon-SA or of the specific integration within Oxygen?

Example:

declare variable $target := <whatever>some text</whatever>;
copy $t := $target
modify rename node $t as "something"
return $t

Fails with message "Node to be renamed is not an updateable node".

Hello,

Thank you for reporting the problem. We fixed it and uploaded a new build on the Download page. Please reinstall Oxygen 10.3.

I was just testing out XQuery Update in oXygen and came across this thread. Using build 2009090215, I tried the example:

declare variable $target := <whatever>some text</whatever>;
copy $t := $target
modify rename node $t as "something"
return $t

But this fails for me with the following error:

SystemID: /Users/joe/Downloads/Untitled9.xquery
Severity: error
Description: Expression class net.sf.saxon.instruct.TraceExpression is not an updating expression

By the way, I was working in the XQuery Debugger window with Saxon-SA XQuery 9.1.0.7 selected as the Debugger engine.

I wonder if this is an XQuery error or an error with oXygen/Saxon?

Thanks for any suggestions,
Joe

Hello,

The query works correctly in the Editor perspective (just XQuery execution without debugging) but not in the XQuery Debugger. I think it is a bug in the Saxon SA processor. I reported it to Saxonica and we hope they will fix it soon.

Thanks, Sorin. That's good to know. I'll look out for a future update on this issue.

Hello joewiz,

Michael Kay fixed the problem on the Saxon 9.2 code branch. The current version is 9.2.0.2 so the fix will be included in the next Saxon 9 version that will be released by Saxonica. We will include that Saxon 9 version in Oxygen after Saxonica will release it.
