Hi all, do you have any idea how to solve following problem:
We have input xml MessageSet1 with elements:
element1, element2 .. element15
Output xml MessageSet2 with elements:
element1, element2 .. element10
The element names from MessageSet2 are the same as in MessageSet1, MessageSet2 is subset of MessageSet1.
MsgSet1--> Flow --> MsgSet2
How to create output message generaly, when we do not want to name elements directly in ESQL (we have a lot of such a situations, so we would like to solve it generaly). We need to go through MsgSet2 elements and look for such an elements in MsgSet1.
How could we go through all output MessageSet elements? |

Use a Mapping node.

Thanks a lot for a quick answer.
The problem is that I do not know exactly the MsgSet1. (you can imagine that MsgSet1 is sequence of xsd:any). I know only MsgSet2.
I want to create output message matching the MsgSet2 and fill its elements from input message, if they are included in input message with the same name.
This is what I want to do for many MsgSets2, so I'm looking for general way how to do it. |

The only possible way to do this is to create a fully formed, but empty, message from message set 2.
Then loop over the fields in Msg2 and use the fieldname to get the same named field in the input message (based on MsgSetX) and set the value into the output message.
Your requirements, by the way, are completely ridiculous. There's absolutely no good reason that a random message that shows up on an input queue that happens to have a field called "AccountID" (for example) will in ANY WAY have the same business meaning as the field called "AccountID" in your output message.
And then there's the whole question of what if there are TWO fields called "AccountID" in the input message, and only ONE field on the output message.
