        Hi All,

        In a orchestration for handling message validation errors, I use a Receive port with Direct binding, and it recieves a message of type XmlDocument. Since it is Direct binding the well formed ness of the document is not checked and whatever there is comes into the orchestration. In the orchestration I want to check if the document is well formed or not, if it is I return the message body with the response message to the client, so that he can check where the message went wrong. Other wise if the document is not well formed, I just tell him that your xml was not valid.

        The problem is I cant use try catch in Expression shape to check for the well formedness of the xmldocument. Please tell me a way using which I can check its well formedness in the orchestration.

         

        Regards,

        Sajid.

          It depends on how you are loading the XmlDocument object…

          LoadXml does not perform validation, and Load would require you to utilize a XmlValidatingReader and ValidationEventHandler for validation…you could consider using either method within a Pipeline Component and manage any exceptions at the disassemble stage before it hits your port.

          My $.02, but I'm sure the actual Guru's may have a solution as well.

              You can create a try/catch block in the orchestration using a scope.

              In an expression shape in the scope

              xmlDocVariable = incomingMessage;

              Add an exception handler to the scope to catch System.Xml.XmlException
