Pre-Req
convert utility :sudo apt-get install imagemagick
curl utility :sudo apt-get install curl
Any wallpaper : it's called rss.jpg here

The idea is pretty native :
Step 1 : Get the rss feed URL
Step 2 : Scrap for the data
Step 3 : Set the data as wallpaper

Code template

#!/bin/bash
<b>convert -font helvetica -fill white -pointsize 36 -draw \
'text 500,500 "This is the data from the rss feed"' \
rss.jpg rss-current.jpg</b>
while [  1 ]; do
        COUNTER=0
        while [  $COUNTER -lt 10 ]; do
        <b># grep for text as per your requiremnet</b>
        text=`curl -s $URL | grep CDATA` 
    <b>cmd="convert -font helvetica -fill white -pointsize 40    -draw 'text 500,500 \"$text\"' rss.jpg rss-current.jpg"</b>
 eval $cmd       
   temp=$(stat -c%s black-current.jpg)
                if [[ $temp > 1000 ]]
                then    
           eval $cmd
                break
                fi
                sleep 5
                let COUNTER=COUNTER+1 
        done
        sleep 3
done

Now just run the coe as background process :
$ ./rss.sh &
You will find a new image called rss-current.jpg in the same path as your script, set it as a wallpaper and stay updated.
