[xquery-talk] Namespace conflict ?

[Christian Grün]

Hi Leo,

> I thought the function local-name() produces an output  without namespace binding? Can anyone explain?

You are completely right. The problem is that your original document
uses the default namespace "http://www.mygym.com", and your query uses
"http://www.gym.com". In other words, the error is raised because the
namespace binding of your target name conflicts with the existing
namespace binding.

Here is a recursive approach to change the default namespace of a document:
______________________________________

declare function local:update($root as node(), $ns as xs:string) {
  if($root instance of element()) then (
    element { QName($ns, local-name($root)) } {
      $root/@*,
      for $node in $root/node()
      return local:update($node, $ns)
    }
  ) else (
    $root
  )
};

let $ns := 'http://www.gym.com'
let $root := doc("FitnessCenter.xml")/*
let $updated := local:update($root, $ns)
return replace node $root with $updated
______________________________________

Hope this helps,
Christian
