Customizing RSS Feed

I have children pages that I would like to display in rss xml using page.feed.rss.xml. I placed the /feed.jsp and /feedentry.jsp from /libs/foundation/component/page into my /apps/[project]/component/page and to change the defined atom:link and atom:publish. However, the rss feed is not picking up the change. It does not appear to be pointing to the feed jsp under /libs/foundation/components/page which the sling resource resolver for /page.feed shows /libs/sling/servlet/default/feed.jsp. I have even tried creating feed.rss.xml.jsp in my project page component with no success.

Also the sling servlet resolver referenced com.day.cq.commons.servlets.FeedRendererServlet and I wondering if the returned atom xml goes through this render to get the resulting xml page.feed.rss.xml. If that is the case, I would I go about making changes to the atom:publish and atom:link.

I was doing a similar thing.
It is possible to override the "foundation/components/primary/cq/Page/feed.jsp" to control you own way of what should be included in the feed from the page that you "start from", in you case "/content/tod.feed.rss.xml". There you can then make you own iterator to further specify which pages under the root page that should be listed. If you don't want any pages at all or just properties from the page itself you can implement that there as well.

I might have missed something but if there are only things under the jcr:content it would be quite easy to just extract them from the page you are iterating over in your new overlay of the feed.jsp.
Either you overlay the feedentry.jsp as well and then you can change what goes into all the different elements such as:

<atom:entry id="<%= myCustomUrl %>" updated="<%= myCustomDate1 %>" published="<%= myCustomDate2 %>" > <atom:title><%= myCustomTitle %></atom:title> <atom:link href="<%= myCustomLink %>"/> <atom:content><%= myCustomContent%></atom:content> </atom:entry>

You could also have it in the same file i guess if you don't want to include the feedentry.jsp for the page. But that I guess is entirely up to you.

One heads up for working with these files is that they are VERY sensitive when it comes to line breaks and extra spaces that you are not allowed to have in your jsp files.

Hi Anjali,

if your facing special characters issue in atom. For this you need over ride the existing feed servlet and create own class. It solved my problem. Atomfeed.java class which implements feed interface create your own class which implements feed and write your logic. Hope it helps

Thanks,

Haarsh

Try with [1] which includes jcr:content & it works. To avoid jcr:content in the url create a proxy example Page.feed.jsp with text from [2].

[1] http://localhost:4502/content/tod/jcr:content.feed.rss.xml

[2] /libs/foundation/components/primary/cq/Page/proxy.jsp
