XQuery/Registered Modules

Motivation

You want to check to see if an module is loaded in your runtime systems.

Method

Some modules that you may need are not loaded into the runtime engine when the server starts. If this is the case you may have to dynamically load a module.

Listing current modules in the runtime

xquery version "1.0";
 
let $modules := util:registered-modules()
return
<results>{
   for $module in $modules
   order by $module
   return
      <module>{ $module}</module>
   }
</results>

Run
