Hope I didn't miss understand your question. To setup a RSS export you only need to access your eZ Publish siteadmin interface.
Go to: <b>Setup -> RSS -> New export</b>
Fill out information about your RSS feed. Pay specially notice to the <i>“Site URL”</i> parameter that will be used for all links in your RSS export. Also pay notice to that you need to click the <i>“set”</i> button after changing class that you want to export before the <i>Title</i> and <i>Description</i> drop-down box updates.
By default <i>Anonymous Users</i> don't have access to read RSS feeds. You will need to update the policy for the <i>Anonymous role</i> to access the module <i>“RSS”</i> and function <i>“feed”</i>
Here is an example that shows how we been exporting the Article class in our sub-folder News:
your reply was a big help and I have now managed to create a news feed, which I can access if I put the url directly into the address bar.
However this rss feed is not being picked up by the link.tpl and turned into a link. Instead I am getting a reference to a dummy rss feed that was already set up called my_feed. I have deleted this on the setup > rss but it is still (despite clearing caches several times!) showing in the links:
I guess you use the websiteinterface or ezflow, in that case login to your front page and click site settings to change the rss url among other things.
Changing the rss feed in the site settings is great for one rss feed. But what about when you have several of them (as the ez.no site does). Is it necessary to edit/override link.tpl or is there another way?
