RSS feeds - How to read a tag like "dc:creator"

To dealing with the "News Feed" Items, I have installed a plugin called "RSS". 

I find that there is a "Items" List which includes the attributes like "Title", "Link", etc. 

However, my "News Feed" includes a tag <dc:creator>, E.g.
<dc:creator><![CDATA[Tomáš Foltýn]]></dc:creator>

I would like to know if it's possible to read the content by the RSS plugin ????

Many Thanks in advance ~~~
