How to read an XML file on the internet using a servlet & to upd ate an internet database

Hi all,

I have a scenario in which a servlet reads an XML file located on the
internet. I know the IP address of the machine on which the XML file is
located. I have to read that XML file and do some processing and then update
another database located on the internet, the IP address of which is also
known to me.

Please tell me how to do all this, and what kind of set up( web server, etc)
i need on the servers hosting the XML file and the database.

regards

ashish sarin
