Thank you very much, Christian, a tip much appreciated! It works. In case
(quite improbable) that someone else faces the requirement to add namespaces,
retaining the base URI, I add the code of a function I wrote for this operation.
Kind regards,Hans-Jürgen
PS: Is it not simply oversight that the Update spec does not support the
insertion of namespace nodes, although XQuery 3.0 does define their
constructors? Would a feature request have any chance?
(:~ : Adds namespace nodes to a node, retaining its base URI. : Note that
the namespaces are added to the root element of : the incoming document or
fragment. :) declare function f:addNamespaces($node as node(),
$namespaces as
namespace-node()*) as node() { let $root := $node ! root() let
$fnElem := function($n) {$n/descendant-or-self::*[1]} let $prefixes :=
$namespaces ! name(.) let $uris := $namespaces ! string(.) return $root
update { for $p at $pos in $prefixes let $uri :=
$uris[$pos] let $attName := QName($uri, $p||':_') return
insert node attribute {$attName} {()} into $fnElem(.) } update {
let $elem := $fnElem(.) for $p in $prefixes
return delete node $elem/@*[name() eq $p||':_'] }};

It feels a bit clumsy, but adding a prefixed attribute and removing it again
should do the job:
let $xml := doc('x.xml') let $updated := $xml update { insert node <a
xmlns:prefix='URI' prefix:attr=''/>/@* into * } update { delete node
*/@attr } return ($updated, base-uri($updated))
Best,Christian

Betreff: Re: AW: [basex-talk] Add namespace bindings via copy/modify/return
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,ChristianVon: Hans-Juergen Rennau via BaseX-Talk

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
