Simply :

"<first parameter>value</first parameter> <second parameter>value</second parameter>
...... "
"</stateWiseHospitalName> /n "

iOS doesn't have any built-in support for SOAP, so you may want to find a library to help with creating and interpreting SOAP messages. If you're comfortable doing that yourself and just need help to post the message to a server, you can use NSURLRequest and NSURLConnection for that.

I don't recommend using SOAP. Been there, done that, it's a gruelling experience.

I prefer using JSON for web services. The folks at http://www.three20.info have a comprehensive framework to dealing with it.
