Setting up Route for Category-based RSS Feeds I think that I need to set up a few routes to handle my category based RSS feeds. I have a current url structure as follows

http://something.com/shows/wmr/marketing pr

http://something.com/categoryGroup/parentCategory/childCategory


I need rss feeds from both the parent and child categories

http://something.com/categoryGroup/parentCategory/feed
http://something.com/categoryGroup/parentCategory/childCategory/feed


The rss template i am using is stored in 

categories/_shows.rss


I have munged something together in the cp routes settings but I would prefer to have this in routes.php. Having access to the parentCategory and childCategory values without doing a segments thing would be nice.
Okay, I think that I have figured it out. Posting here for posterity. Based on the requirement above, I put these in my routes.php file.

'shows\/(?P&lt;parentSlug&gt;[a-zA-Z0-9\-\.]+)\/(?P&lt;childSlug&gt;[a-zA-Z0-9\-\.]+)\/feed' =&gt; 'categories/_shows.rss',


and

'shows\/(?P&lt;parentSlug&gt;[a-zA-Z0-9\-\.]+)\/feed' =&gt; 'categories/_shows.rss',


This gives me two variables. parentSlug and childSlug
