I have implemented rss feed for my site.Took help from http://www.script-tutorials.com/how-to-easily-make-your-own-rss-feed/
Now it shows only title and description in feed page.But i want to show more info like property location and property type.So i have used
<location>
<![CDATA[ example ]]>
</location>
<property_type>
<![CDATA[ example]]>
</property_type>
I have used it inside the item tag.But on feed page it doesn't shows but after pressing ctrl+u i can see the xml code.
You can't invent your own elements (that aren't part of RSS) and expect an RSS client to do anything with them.
If you want to display additional content in a generic RSS client, you need to write it in HTML and make it part of the regular content.
