Web service in Delphi 5

Question

Using Delphi 5, can I call a function in a web service that is developed in VB.Net and has some parameters and returns XML? If so, which components will I use to call the web service function and the XML that this function will return?

Answer 1

I think that support for web services (SOAP) was introduced in Delphi 6.
Switching to a new version of Delphi will certainly be the easiest way.

If you cannot, you need an external library that implements SOAP support.
