I know how to connect to web server using an iPhone but now I have to connect the iPhone to a web service. I don't know how to do it and there is no demo or class available online.

Does anyone have any ideas?

You might find this tutorial, called Intro to SOAP Web Services useful. He shows how to package a request, send it to a web service, and read the response.

If you need some help with XML parsing, there is the TouchXML library which will give you a nice xml "document" to work with. Just be cautious of memory usage.

If you have to parse large XML message this tutorial about libxml and xmlreader in Cocoa will show you how to parse XML with the lower-level event-style parsers.
