Don't let the title scare you: Livingston teaches SOAP from scratch. But he does take you to some pretty "advanced" territory. Livingston covers all of the standards that complement SOAP, including WDSL, UDDI, and even Disco, Microsoft's local solution for web services discovery.
There's detailed coverage of SOAP and RPC (including a chapter on XML-RPC, essentially a simpler, stripped-down SOAP with much shared history. You lose goodies like user-defined data types, but XML-RPC still lets you solve the core problem: transmitting, processing, and returning complex data structures).
Chapter-length projects walk you through setting up SOAP servers, clients, and web services. There's a full chapter on SOAP troubleshooting, and another on SOAP language bindings. The focus is on getting results -- and you will. (Bill Camarda)
