Hi

I have this weird issue with my xquery script.
The below script returns XML where the namespace prefixes are changed to weird generated namespace prefixes.
The result is valid, but is looking weird.
The namespace changes are located within the output for all elements included in the for loop, resulting in elements looking like this:

<ddtek-me1:DespatchLine xmlns:ddtek-me1="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2">
<ddtek-me2:DeliveredQuantity xmlns:ddtek-me2="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" unitCode="STK">1</ddtek-me2:DeliveredQuantity>

This is the script:

declare namespace b = "urn:oasis:names:specification:ubl:schema:xsd:DespatchAdvice-2";
declare namespace a = "http://generic.xml.eetgroup.com";
declare namespace cbc = "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2";
declare namespace cac = "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2";

declare option ddtek:serialize 'indent=yes,omit-xml-declaration=no';

for $Dispatch in /a:DispatchAdvice/a:Dispatch
return
<b:DespatchAdvice xmlns:b="urn:oasis:names:specification:ubl:schema:xsd:DespatchAdvice-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2">
<cbc:UBLVersionID>2.1</cbc:UBLVersionID>
<cbc:CustomizationID>somthing</cbc:CustomizationID>
<cbc:ProfileID>gggggg</cbc:ProfileID>
<cbc:ID>TODO: dispatch ID missing from Generic file</cbc:ID>

<cbc:IssueDate>{ year-from-date(current-date())}-{ month-from-date(current-date())}-{ day-from-date(current-date()) }</cbc:IssueDate>

{
for $DispatchLine in $Dispatch/a:DispatchLines/a:DispatchLine
return
<cac:DespatchLine>
<cbc:DeliveredQuantity unitCode="{ $DispatchLine/a:UnitOfMeasure/text() }">
{ $DispatchLine/a:DeliveredQuantity/text() }
</cbc:DeliveredQuantity>
<cac:bcOrderLineReference>
<cbc:LineID>
{$DispatchLine/a:OrderLineReference/text() }
</cbc:LineID>
</cac:bcOrderLineReference>
<cac:Item>
<cbc:Description>
{ $DispatchLine/a:Item/a:Description/text() }
</cbc:Description>
<cac:SellersItemIdentification>
{ $DispatchLine/a:Item/a:VendorsItemNo/text() }
</cac:SellersItemIdentification>
<cac:ManufacturersItemIdentification>
<cbcID>
{ $DispatchLine/a:Item/a:ManufacturerPartNo/text() }
</cbcID>
</cac:ManufacturersItemIdentification>
<cac:StandardItemIdentification>
<cbc:ID>
{ $DispatchLine/a:Item/a:EAN/text() }
</cbc:ID>
</cac:StandardItemIdentification>
</cac:Item>
</cac:DespatchLine>
}

</b:DespatchAdvice>

Appreciating any input, thanks.

You can obtain what you want avoiding to clash namespace prefixes

In the query prolog, you have the following definitions:

declare namespace cbc = "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2";
declare namespace cac = "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2";

The literal element has the same namespace definitions:

<b:DespatchAdvice
xmlns:b="urn:oasis:names:specification:ubl:schema:xsd:DespatchAdvice-2"
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"

Simply renaming the namespace prefixes to cbc1, cac1 as following, prevents the XQuery engine to create additional namespace declarations in the query output

declare namespace cbc1 = "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2";
declare namespace cac1 = "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2";

In this specific query, you can safely remove the namespace declarations all together

declare namespace a = "http://generic.xml.eetgroup.com";
declare namespace b = "urn:oasis:names:specification:ubl:schema:xsd:DespatchAdvice-2";

(:
declare namespace cbc1 = "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2";
declare namespace cac1 = "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2";
:)

declare option ddtek:serialize 'indent=yes,omit-xml-declaration=no';

Thanks, now I can see that I only need to declare the namespaces in the ingoing document.
