Getting the pages in a given category. - Mediawiki-api

19 Jul 2009


      Hi all,
using the mediawiki API, I can list the pages  in a given category. For example:
http://en.wikipedia.org/w/api.php?action=query&list=categorymembers&...
returns:
<?xml version="1.0"?>
<api>
   <query>
     <categorymembers>
       <cmpageid="22939"ns="0"title="Physics"/>
       <cmpageid="24489"ns="0"title="Outline of physics"/>
       <cmpageid="1653925"ns="100"title="Portal:Physics"/>
       <cmpageid="3445246"ns="0"title="Glossary of classical physics"/>
       <cmpageid="22950086"ns="0"title="Britney Spears' Guide to Semiconductor Physics"/>
       <cmpageid="2129107"ns="14"title="Category:Fundamental physics concepts"/>
       <cmpageid="4769321"ns="0"title="Timeline of fundamental physics discoveries"/>
       <cmpageid="694942"ns="14"title="Category:Physicists"/>
       <cmpageid="1198"ns="0"title="Acoustics"/>
       <cmpageid="1913676"ns="14"title="Category:Applied and interdisciplinary physics"/>
     </categorymembers>
   </query>
   <query-continue>
     <categorymemberscmcontinue="Atomic, molecular, and optical physics|"/>
   </query-continue>
</api>
I now want to limit my query to only one MW namespace. I have tried to use the cmnamespace parameter. But
http://en.wikipedia.org/w/api.php?action=query&list=categorymembers&...
returns the same result. How should I use this namespace parameter ?
