MediaWiki

User:DaSch/generateSitemap.php

< User:DaSch

Because the given generate Sitemap from MediaWiki is not the best solution I made some changes to give the possibility to generate the sitemap the way you may want it to be. For example I can generate sitemaps for my six domains wecowi.de, wecowi.com, wecowi.org, wecowi.net, wecowi.eu and wecowi.info and put them into different directories.

Another case is that all pages could have a different priority, so I made it random because I'm not a PHP-Coder and do not know how to create a better solution.

I put this here because my bugreport was ignored. I hope I can help you with this.
