Example

• Retrieve the modules stored in the current collection as non-XML data:

  declare namespace ino="http://namespaces.softwareag.com/tamino/response2"
  root(
   for $a in collection("ino:source")/ino:module
   where $a/@ino:targetNamespace="http://www.examples.com/tree"
   return $a
  )

  The query returns all those modules as document nodes that are in the namespace http://www.examples.com/tree.
