Converting Delimited string to XML message

Question

Hi,
We are trying to convert pipe delimited string into a xml schema using a XSD and BPEL funtion. Consider a scenario in which message has 5 fields with last as 2 optional fields. So the incoming string message can be like "1|2|3" or "1|2|3|4|5". In this case how the XSD should look like, since for each field we have to give "terminatedby" option in the XSD. So the issue is coming for element 3 where the delimiter can be "|" or "eol" (end of line). How to specify that ? Is there any option to use like "optionally terminated by?"
Any help will be appreciated.
Thanks,
Ramesh

<!--NXSDWIZ:D:\DBIN\ReadFile.txt:-->
<!--USE-HEADER:false:-->But in your case if you are getting 5 elements instead of 3 elements in some other file....Use the same and maipulate the last element afterwards.
I think we can not have an element definition for two scenarios.
Update you if i get any..
