WSDL and SOAP?

[tobiah]

I need to link an event registration site to
a housing site. From what I can gather, I
make a call to some url that ends in WSDL, and
get some XML back from the housing site. Now I'm
supposed to make this into an object and call it
here and there through SOAP? Is that how it works?

Is this the best place to start?:
