Hi Computer Software Developer,

I had a look at your issue - I attached my setup for reproduction,
to make sure there aren't any errors on my side. You can start
it by calling

'java -cp BaseX.jar org.basex.BaseX < commands.txt'

For me it works fine with the actual release you can get
from [1]. Which version of BaseX are you using?

Regarding the insert issue: Are you trying to insert something
into an APPLICATION element which is deleted by the delete
statement - in this case the insert operation is not carried out
at all - as a result of optimization processes. Depending on
what you want to do, I'd be happy to help you out ... just let me
know.

Feel free to ask for more.

Regards,
Lukas

Hi,

I have a collection MyData/Test and another collection MyData/Real.  I
have the following XML occurring about five times in total, 4 times in
collection MyData/Test and once in MyData/Real:

<APPLICATION>
<APPLICATION_ID>1</APPLICATION_ID>
</APPLICATION>

When I seek to delete this application only from MyData/Test using
updating xquery like so:
xquery version "1.0";

declare namespace fn="http://www.w3.org/2005/xpath-functions";

let $dataSet := 'Test'
let $databaseName := 'MyData'
let $applicationID := '1'

let $finalURL := fn:concat($databaseName, "/",$dataSet)
let $applicationsModified := &lt;APP-DATA-ROOT
xmlns:xforms="http://www.w3.org/2002/xforms"&gt;
&lt;APPLICATION&gt;
   &lt;APPLICATION_ID&gt;2&lt;/APPLICATION_ID&gt;
 &lt;/APPLICATION&gt;
&lt;/APP-DATA-ROOT&gt;

for $all in fn:collection($finalURL)
       for $anApp in $all/APPLICATION[APPLICATION_ID=$applicationID]
return
(
delete nodes $anApp
)

The application gets deleted from MyData/Real collection as well!

Moreover, an insert statement to insert an APPLICATION element in the
return block above, such insert statement placed after the deletion
statement above, does not appear to insert anything.
