Hello,
I found some code by Craig B to navigate recursivly through an unknown xml tree to find a tag, http://www.mqseries.net/phpBB2/viewtopic.php?t=10065&highlight=lastmove+procedure. I have changed this a little to search for specific content of a tag in an unknown tree. The trace shows that this is working. However I need to return the reference from the procedure so that I can continue processing the data(parse the embedded swift). So far I have not been able to do this, does anyone have a possible solution? My code is below, please note that at present to quicky validate the success/failure i am just testing the FIELDNAME of the reference.
Many Thanks

DECLARE foundMatch BOOLEAN FALSE;
DECLARE OutboundMsg REFERENCE TO InputRoot.XML.TPCIMessage.OutboundMessage;
CALL navigate (OutboundMsg, foundMatch, '{1:');
IF foundMatch = TRUE THEN
SET OutputRoot.XML.TPCIMessage.Tag = FIELDNAME(OutboundMsg);
END IF;
CREATE PROCEDURE navigate (INOUT OutboundMsg REFERENCE, INOUT foundMatch BOOLEAN, IN searchText CHAR)
BEGIN
DECLARE MatchingPattern CHARACTER;
DECLARE cursor REFERENCE TO OutboundMsg;
SET MatchingPattern = SUBSTRING(OutboundMsg FROM 1 FOR 3);
MOVE cursor FIRSTCHILD;
IF LASTMOVE(cursor) THEN
ELSE
IF MatchingPattern = searchText THEN
SET foundMatch = TRUE;
END IF;
END IF;
WHILE LASTMOVE(cursor) AND (foundMatch = FALSE) DO
CALL navigate(cursor, foundMatch, searchText);
MOVE cursor NEXTSIBLING;
END WHILE;
END;
