I just got a Ethernet Shield for Christmas 
I want to now make a Multifunction LED Matrix (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1275865385)
How would I do this but instead of using serial use the ethernet shield to connect to the internet and send the data to the led matrix.
If you look at my previous posts you can see how I have the led matrices set up.
Thanks... Chris
The ethernet shield needs to be running as a client, doing a GET operation, on some regular schedule.
The URL that the client gets needs to contain the data to be parsed to define the data for the matrix to display.
So after doing much research I have decided that I want to make an RSS Feed and display that feed on an LED Matrix. What can I do?
Please, Can some one help me?
Well, if you can provide the technical operating details of an RSS feed, then maybe somebody can provide possible options for interfacing it with an arduino.
Most of those were tutorials on how to display an RSS feed on an LCD. If it is simple to switch the lcd with led matrices how could I do that?
If I could get at least a library or a link that explains how to send rss via ethernet to an led matrix that would be great.
It should be obvious that this is a two step process. First, the data needs to be send to the Arduino. Then, the data needs to be sent to the LED matrix.
Which part do you need help with? If the answer is both, I think it's time you got out of the deep end of the pool, and learn to do some things on your own.

Do you wat to send or receive the rss feeds? A logical point would be to use dummy strings to get your led matrix working, then work on capturing the rss feed.
I want t recieve a custom made rss feed (weather, date, time) and display it on an led matrix.

So, now you have 4 things you want to do. Construct the RSS feed. Send that data to the Arduino. Receive that data on the Arduino. Send that data to the LED matrix.
Which of those things can you do?
retrieve RSS feed from internet (via ethernet shield) -----> display rss feed on LED matrix
retrieve RSS feed from internet (via ethernet shield) -----> display rss feed on LED matrix
If you can get the feed from the internet, and display that on the LED matrix, what do you need help with?
No, I cant get the feed setup, and I cant display it on the led matrix. That is what I need help with.
I still cant figure it out.
Well, the below indicates the rss file is an xml file that probably could be obtained with a get request. While the file is downloading you probably would have to extract the desired data, and send it to the display. Bottom is a recent discussion on extracting data.
How do I create a Live XML File? I want to download the data from that and display in on the LED matrix. (I am finally getting the idea!)
Would I be able to create a xml file with pachub?

From the example in the link provided, I think you could make an xml file just using notepad and saving as .xml. As to pachub, maybe there is a pachub discussion group somewhere with info.
Ok, How would I host a live xml file on the internet?

You will need to provide technical details as to what a "live xml file" is, and "host" is usually closely connected with the term "server".
