      Hi clovertechs experts,

      I have a problem with the iterate function of XLATE.

      I have to translate one XML to another using XLATE.

      I am using the iterate function and gererating two xml. Below are my simplified samples



      [code]

          My guess would be the position of the ITERATE variable in the address path of the COPY(s) does not match the position specified in the basis for the repetition.

          So the ITERATE does walk over the repetitions but the COPY(s) point to only the first repetition.

          I would need more information to be more help.

            As procedure B doesn’t have an observation, the translation will not find the observation and totally skip the COPY statement as there is no input. So in the second iteration the observation is not touched and the output remains ” Some Observation”.

            Try putting a

            Code:

            COPY @null -> order_element.newobservation.#text


            before you fill newobservation with the value. This should help.

              Unless XML is different doesn’t the Xlate treat non existent fields as null and thus complete the copy using null?

                XML translating is different from HL7 translations and I have seen this behaviour in our translations before.

                You will get a @null result if the inbound XML is

                Code:


                  1
                   
                     
                        Procedure A
                        Some Observation
                   
                   
                      Procedure B
                     
                   
                 


                or even

                Code:


                  1
                   
                     
                        Procedure A
                        Some Observation
                   
                   
                      Procedure B
                     
                   
                 

                But if the ‘tag’ is not there, the Xlate COPY will not be performed. I guess because the field is not there, the translation can’t even perform the COPY.

                Can’t test it quickly right now though.

                    The two examples that you mentioned worked as expected. And I will put this @null before each copy statement.

                    Thank you Robert Kersemakers

                    it works.
