InfoPath Dev

I have a stored procedure that returns a comma seperated value.  Actually a web service returns the value from the stored procedure.  example string:  PC, Mouse, Monitor

is there a simple way to make that populate into a drop down on an infopath form  PC as one option, Mouse the other and Monitor the last. 

ideas?  i might try to do what i need  in the webservice, but got to learn that as well.

i solved my problem not for just this project but for many others.  i just declared an array, populated it with the values in the webservice and added it as a secondary data source...works great.
