[MarkLogic Dev General] External Functions

[Colleen Whitney]

Hi Gary,
 
If I understand your question correctly, what you need to do is write a
library module, then import it in a main module.
 
  
(: common.xqy :) 
module "http://www.w3.org/2003/05/xpath-functions" 
define function uris() as xs:string* { 
  for $n in collection() 
  return xs:string(xdmp:node-uri($n)) 
}

In XQuery Specifications they allow for functions that are defined as
external.  I have read through the documentation but do not see how to
call them in MarkLogic.  Ideally I would like to develop a interface
type of functionality to allow another module to define the
implementation of the module and allow that called module to use that
function.  But I don't see how this can be implemented.

 

Ex. 

 

Module "urn:my-hello-world"

 

define function hello-world($name as xs:string) as xs:string external

 

??How would you call this module???
