David JaramilloSubject: namespace information with XQuery

Hello,
Does anybody how to output the standard namespace information for xml in Xquery using the element construct?

I use for instance:

declare namespace xs="http://www.w3.org/2001/XMLSchema-instance";

and use a construct like:

element root { attribute name2 {value2}, element name3 {value3}}

to build the root element. I want the declaration

xmlns:xs="http://www.w3.org/2001/XMLSchema-instance

to be output in the root element. How do I achieve this?
Any help would be greatly appreciated

Thanks,
David

Hi David,

The beauty of XQuery is that you can create literal XML

<root xmlns:xs="http://www.w3.org/2001/XMLSchema-instance name2="value2">
<name3>value3</name3>
</root>

If you need to evaluate an expression placed inside {}

Hope this helps

Hello Ivan, thanks for the reply.

I need a solution for the element construct not the literal one, The reason I am trnasforming from one structure to another with Xquery and in somtimes little or no change is made to a complex structure, so I don't want to built everthing literally.
Is there any solution for the element constructor?

Thanks,
David

My understanding is that is the processor responsibility to generate the in scope name-space definitions when they are referenced. It seems like that our built-in processor doesn't honor that but you if try the following with Saxon it should work fine.

declare namespace xs="http://www.w3.org/2001/XMLSchema-instance";
element root {
attribute name2 {"value2"},
attribute xs:test {"value2"},
element name3 {"value3"}
}

So in short if and only if you use the prefix the declaration will be create for you.

Hope this helps
