how to incorporate types from a XSD to the WSDL in NuSOAP

I'm trying to create a webservice for a PHP app (with CodeIgniter) using NuSOAP, and I'm finding some difficulties since creating a WS from scratch is new to me. I have some XSDs that I should use to validate the input (which will be an XML with many records of one of 3 complexTypes just inside the root). Now, I know I could use the addComple开发者_开发技巧xType method and put each one of these myself, but isn't there an easy way to import the definitions from the XSD? besides, isn't there any Nusoap reference? I can't find one! just tutorials and question threads =/

You can just add the xsd directly into the <wsdl:types> tag in the WSDL, that would add all the complex types. By the way, if you have a fixed WSDL, then you're probably better off not using NuSOAP at all.
