Web App based on google maps

[Ricardo Triana]

Hello:

I just started my research for my first google maps based web app. Im
looking to do something like this:

http://www.mapnificent.net/

But all i need to do is to have only external info loaded from an RSS
or an XML file (Not sure). I kno i can do this, I just havent been
able to find the way to do it. Also I would like to style my map (I
know I can only do so much with this, but its ok) and I would like to
integrate a small internal search engine(limited tags) for my users to
be able to surf for the info.

Im sure this is a pretty simple matter, but I would love for you guys
to point me into the right direction.

Thanks for your time and understanding.
