Currently the exceptions are returned in the content of the faultdetail. You will need to do perl string searches to extract the relevant codes. We were limited with the SOAPv1.1 schema in how we could include detail in the faults so we segmented them on separate lines in the faultdetail so line greps code be done for the exception elements (primary_error_code, secondary_error_code, error_string), then the string can be cut at the ":" for the relevant data. I will look into getting some perl code to do this later today and post it as a reponse to this thread.
BTW, With the upcoming SOAP v1.2 faults, more detail will be able to be included in the soapfault elements!
