I'm using IBM WESB in my project. In one of the scenario I would like to validate the content of the object,.(For example: I'm using a simple dataobject <acc id>. If the <accid> tag has value then proceed the flow else return to fail terminal. I'm using message validator. According to my knowledge the validator just check the schema and not the value inside the tag. Is there any method or primitive that I can use to validate the content in the xml tag. ?
