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.
