Hello,

writing a RESTXQ application, I have the following code in a module:

module namespace page = 'http://localhost/web-page';

declare %rest:path("/list/{$category}") %rest:GET %rest:query-param("page:category", "{$category}") %output:method("xhtml") %output:omit-xml-declaration("no") %output:doctype-public("-//W3C//DTD XHTML 1.0 Transitional//EN") %output:doctype-system("http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd") function page:list($page:category as xs:string) { () };

I get:

[basex:restxq] Variable $category is not specified as argument.

If I replace *every* '$category' with '$page:category' I get:

[basex:restxq] Variable $page:category is specified more than once.

But the only place I use '$page:category' in this module is at this point.

The rules are, as far as I have understood:

1. In a module, only one namespace can be used for the functions and variables defined therein, foreign namespaces can be sourced via module imports only. 2. This namespace can not be in the {http://www.w3.org/2005/xquery-local-functions%7D namespace, but must go into my own namespace, here {http://localhost/web-page%7D. 3. All variables must be in the relevant namespaces *(global or local only?)*.

I now have tried several approaches. As I see in the XQM modules in the BaseX DBA application, it seems, that neither the '%rest:query-param' is needed nor is it needed to prefix variable/parameter names, that are local to that function. This can be found, for example, in 'dba/common.xqm':

module namespace dba = 'dba/common'; (:~ : Shows a "page not found" error. : @param $path path to unknown page : @return page :) declare %rest:path("/dba/{$path}") %output:method("html") function dba:unknown( $path as xs:string ) as element(html) { html:wrap( <tr> <td> <h2>Page not found:</h2> <ul> <li>Page: dba/{ $path }</li> <li>Method: { Request:method() }</li> </ul> </td> </tr> ) };

So, I am disturbed by now. What am I doing wrong here?
