Can someone clarify something for me please.
I thought a ResetContentDescriptor, with 'XML' set as the domain and all the other values set to blank, with all the reset boxes checked, was the same as coding in eSQL:-
SET OutputRoot.Properties.MessageDomain = 'XML';
SET OutputRoot.Properties.MessageSet = '';
SET OutputRoot.Properties.MessageType = '';
SET OutputRoot.Properties.MessageFormat = '';
but the ResetContentDescriptor works, whereas the code doesn't.
Could someone explain the difference to me, or point out what is missing from the eSQL to make it work?
There is no real reason for needing this info, other than cosmetic and greater personal understanding!
Many thanks |

Changing the properties of the message doesn't actually cause the message to get a new parser assigned to it.
Using the Reset Content Descriptor does.
You might be able to do everything in a compute node, if you created the new parser in the Output Root and did a couple of other things...
But the RCD node is a) easier, b) more "obvious" what you're doing, c) guaranteed to continue to work as long as the RCD node exists...
So I personally stick with the RCD.
