RSS by user and Forum

[Burgy]

Hello, and Greetings;
since 2005 I am looking for a possibility to view an RSS Feed in an MediaWiki. The feed should look like an query such as:

select posts where forum="XY" and User="Peter Example"

How do I solve the RSS part of the deal. Don?t bother with the look and inclusion I just need the external.php or something else Part of getting this kind of feed out of vBulletin 3.X

Sincerely yours and thank you very much
Yours Burgy
