That heavily depends on your datatypes. Just create an XML sample for your datatype and copy it into the variable or a part. Once the structure is available in your variable, you can access and replace the values of these elements using xpath.
Try adding this copy statement before yours: <copy> <from><literal><return/></literal></from> <to>$Out.parameters</to> </copy> HTH, Tammo [email protected] wrote: > What do you mean about "copy a structural skeleton into the variable" > can you > suggest me a link about or an example... > thank you. > > > >> ----Messaggio > originale---- >> Da: [email protected] >> Data: 17/09/2009 16.42 >> A: <u...@ode. > apache.org> >> Ogg: Re: fault selection error (variable intialization problem) >> > >> Hi, >> >> the response variable must be initialized before a specific xpath can > be >> accessed.
