Creating namespace free Element in xquery

Question

I have created an element as mentioned here XQuery: Create a new element with a given name?.

The code for creating element is below

declare function local:remove-tag-if-empty($elem as element(), $name as xs:string)
{
if(not($elem/node()))
then ()
else
(
element {$name} {$elem/text()}
)
};

Now what I am getting from the generated XML is something like this (I am using the above function to create DOB tag)

<DOB xmlns = "">2012-10-14+03:00</DOB>

I don't want xmlns="" to be the part of the generated xml. Can anyone tell me that how to create element without namespace? Thanks in advance.

Answer 1

Why do you want to create:

<DOB>2012-10-14+03:00</DOB>

It is functionally the same as below:

<DOB xmlns="">2012-10-14+03:00</DOB>
