Thank you, Christian! The problem is that this way I lose the base URI! The only way how to retain it which I am aware of would be the insertion of @xml:base, but this amounts to a change of the document I may not be authorized to do by the context.

Is there any way how to change a document (as modified copy, not via copy/modify/return) and retain or control the base URI of the result, without inserting @xml:base?

Kind regards,

Hans-Jürgen

Hi Hans-Jürgen,

The insertion of namespace nodes has not been defined in the XQuery Update spec. You may need choose the classic element constructor for that:

let $doc := <doc><a/></doc>

return element { node-name($doc) } {

$doc/@*,

namespace xyz { 'https://basex.org/ns' },

$doc/node()

}

Hope this helps,

Christian

Betreff: [basex-talk] Add namespace bindings via copy/modify/return

Dear BaseX people,

I cannot use copy/modify/return in order to add a namespacing:

let $doc := <doc><a/></doc>

return

copy $doc_ := $doc

modify

insert node namespace xyz {'https://basex.org/ns'} into $doc_

return $doc_

<doc>

<a/>

</doc>

Is this a bug?

Kind regards,

Hans-Jürgen
