Hi,
I'm trying to create a msgset that defines a generic CVS with unknown number of repeats. specifically, I want to model a message that can accommodate the following syntax:
ServiceName,parm1,parm2,parm3,...,parmN, with N unknown, only ServiceName is manditory.
So I defined a msg GenCSV with two elelemts,
ServiceName occurance 1, 1
Parms - a complex element containing element parm.
I set parm's occurance to 0, -1. However, based on documentation, "repeating element delimiter" cannot be the same as "Delimiter".
Of course, I can avoid setting the "Delimiter" at messageset level and remove the first element "ServiceName", and use the first element of Parms as ServiceName, and set parm's occurance to 1,-1 and use ',' as repeating element delimiter. But this is not as straightforward for developers.
So here the question: is there a way to get around of the above limitation?

Hi kimbert, thanks for stepping in. Now I know an answer is available.

Are you saying I can use the same delimiter ',' for data element separation and repeating element separation? Or do you mean, I put them all under a single parent element?
- I got it. You mean using a single parent element, containing a first element SvcName with (1,1) occurence, and second element with (0,-1) occurence. This way there should be no confusion for the parser.
But then, why not doing the same at the root level? Will try it out now.

I was suggesting a model like this
| Code: |
Element name="message"
complexType DataElementSeparation="All Elements Delimited" Delimiter="<cr>"
element name="line"
complexType DataElementSeparation="All Elements Delimited" Delimiter=","
element name="ServiceName" ...
group DataElementSeparation="All ElementsDelimited" Delimiter="anythingYouLike"
element name="parameter" maxOccurs="-1" RepeatingElementDelimiter=","
