Feed Reader using AJAX, DOM and JavaScript

Hi all..
This is gonna be my first Technical Post..

Lets say, that you want to write a simple RSS Feed Reader for yourself.
And you dont want to create it using any of the Server Side Web Technologies [ PHP, Servlet, ASP or ASP.NET ]

So, Lets say you want your Feed Reader to be written using only HTML and JavaScript
[ And also lets assume, that you have permissions for making XML HTTP Calls from JavaScript (AJAX) ]

If that is the case, then it goes very simple :

• Make either a synchronous/asynchronous XML HTTP call to ur Feed URL from JavaScript
• Get the response Text of the URL and load it in a DOM Object from JavaScript
• Write a JS function; that parses your DOM Object in the desirable way you need and have the data which u got added to your HTML Page

So, its as simple to write a Feed Reader in minutes with just HTML and JavaScript
I thought of these things, and also implemented the same to read the Recent Blogs of BlogSpace and display their Titles in My Site . It all worked well in my System, but then when i uploaded to Geocities it alarmed with a "Permission Denied" Error, after all am using a free web host and how can i expect them to give me permissions for making Ajax calls from my Html pages.. Huh :( Got little disappointed, though..

But still wanted to share that here, so that it might be useful for some dudes around..
If u need, a sample working model of the same which i hosted in my site.
You can juz save the page of my Sites' Blogspace link and then check and try it out.

Until next post.

[PS: Am not very sure whether i will be posting any more Technical Posts, as long as there are no Tomotoes/Stones being thrown at me for this particular post.. He he he :) ]
