Regarding whois query in xml format

[Rajat <myself_rajat@xxxxxxxxx>]

Hello all,
I am in process of finding the location of a given IP
address. So I made some queries to the whois
servers(using TCP@43), but whatever response I got is
in human readable text formate. More over the response
format of each server is of different form. I compiled
following servers,

whois.arin.net
whois.apnic.net
whois.ripe.net
whois.lacnic.net

I am not able to parse the response and get the
relevent information.

Is there any way to get the response in proper xml
format. So that I can easily parse it. I got one mail
in a message archive, in that it was stated that if we
sand whois query in XML format then will get the
response in XML format only. Other wise simple text
response will be returned.

Does any body know that how we can query the whois
srevr in xml format? And is it depends on servers xml
compatibility??

Thanks in advance.

Regards,
Rajat
