Change the elements displayed on the RSS Feed

Question

I turned on the 'Show Feed Link' located in the 'Integration' tab of a Menu item which then adds the following in the document head:

  <link href="/link?format=feed&amp;type=rss" rel="alternate" type="application/rss+xml" title="RSS 2.0" />
  <link href="/link?format=feed&amp;type=atom" rel="alternate" type="application/atom+xml" title="Atom 1.0" />

Clicking on either takes to either a RSS or ATOM feed which by default shows 5 latest Article. Here is a sample output:

<channel>
    <title>Feed Title</title>
    <description>
        <![CDATA[]]>
    </description>
    <link>http://www.domain.com/link</link>

    <generator>Joomla! - Open Source Content Management</generator>
    <atom:link rel="self" type="application/rss+xml" href="http://www.domain.com/link?format=feed&amp;type=rss" />
    <language>en-gb</language>
    <managingEditor>Editor</managingEditor>
    <item>
        <title>Page Title</title>
        <link>http://www.domain.com/link/item-1</link>
        <guid isPermaLink="true">http://www.domain.com/link/item-1</guid>
        <description>

</channel>

I am trying to modify what is outputted (remove a few elements) but I can't find any settings in the Global Configuration except for number of Feed Items. Is there a way to do it in the backend configuration?

I am also trying to find out where is the code that generates this. I looked in the plugins directory but could not find anything that may generate the above code when the 'Show Feed Link' is selected in the Menu Item 'Integration' Tab.

Answer 1

the file that generates the feeds is located at:

/libraries/joomla/document/feed/renderer

****Joomla 3.x***

But its a core file - so never change that.

You are able to assign a feed module to each categorie for example and then change it via overrides.
