Re: [Exist-open] Computed Namespace Constructor

[Joop R. <jo...@lc...>]

You could create a qualified name and leave out the namespace
declaration:


let $prefix := "gc"
let $URI := "http://www.example.com"
let $elementName := "test" 
let $attributeName := "attribute"
let $attributeValue := "value"
let $elementContent := "This is the element's content"
return

element { QName( $URI, $elementName ) }
             {
              attribute { $attributeName } { $attributeValue } ,
              $elementContent
              }

The result will be correct (assuming you wanted an element with local
name 'test' in the first place!), but the namespace is default and not
with a prefix:

<test xmlns="http://www.example.com" attribute="value">This is the
element's content</test>
