29 ;;; Commentary:
31 ;; To use the SOAP client, you first need to load the WSDL document for the
32 ;; service you want to access, using `soap-load-wsdl-from-url'. A WSDL
33 ;; document describes the available operations of the SOAP service, how their
34 ;; parameters and responses are encoded. To invoke operations, you use the
35 ;; `soap-invoke' method passing it the WSDL, the service name, the operation
36 ;; you wish to invoke and any required parameters.
38 ;; Ideally, the service you want to access will have some documentation about
39 ;; the operations it supports. If it does not, you can try using
40 ;; `soap-inspect' to browse the WSDL document and see the available operations
41 ;; and their parameters.
