De methode viewHistory geeft een string terug als resultaat. Hoe kan ik nu deze methode oproepen en het resultaat in een lokale variabele opslaan?

Greetz!

Ehrm, als je je webservices specificeert in een WSDL spec kun je de skeletons en stubs toch gewoon laten genereren???

ook XML-RPC niet vergeten - dat was bij mij 3 lines of code en geen gezaag (en voor simpel dingen veel handiger dan bloated SOAP)
