Hi All,
My code
| Code: |
IF (InputRoot.XMLNSC.breakfast_menu.food[vIntCount].sex = 'M') THEN
SET vINTFoodCount = CARDINALITY(InputRoot.XMLNSC.breakfast_menu.food[]);
WHILE vIntCount <= vINTFoodCount DO
SET OutputRoot.XMLNSC.menu.food[vIntCount].name = InputRoot.XMLNSC.breakfast_menu.food[vIntCount].name ;
SET OutputRoot.XMLNSC.menu.food[vIntCount].price = InputRoot.XMLNSC.breakfast_menu.food[vIntCount].price ;
SET OutputRoot.XMLNSC.menu.food[vIntCount].description = InputRoot.XMLNSC.breakfast_menu.food[vIntCount].description ;
SET OutputRoot.XMLNSC.menu.food[vIntCount].calories = InputRoot.XMLNSC.breakfast_menu.food[vIntCount].calories ;
SET vIntCount = vIntCount + 1;
END WHILE;
ELSEIF (InputRoot.XMLNSC.breakfast_menu.food[vIntCount].sex = 'F') THEN
SET vINTFoodCount = CARDINALITY(InputRoot.XMLNSC.breakfast_menu.food[]);
--
--
WHILE vIntCount <= vINTFoodCount DO
SET OutputRoot.XMLNSC.menu.food[vIntCount].name = InputRoot.XMLNSC.breakfast_menu.food[vIntCount].name ;
SET OutputRoot.XMLNSC.menu.food[vIntCount].price = InputRoot.XMLNSC.breakfast_menu.food[vIntCount].price ;
SET OutputRoot.XMLNSC.menu.food[vIntCount].description = InputRoot.XMLNSC.breakfast_menu.food[vIntCount].description ;
SET OutputRoot.XMLNSC.menu.food[vIntCount].calories = InputRoot.XMLNSC.breakfast_menu.food[vIntCount].calories ;
SET vIntCount = vIntCount + 1;
END WHILE;
--
-- --SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueName = SIMPLE_OUT;
END IF; |
Problem with this code is it just checks for the first child under'food' and outputs it.Can somebody help me with this?

If this is an attempt to get the training and tutoring you ask for here, then it's going to end badly for you.
Two points:
From a pure code point of view, you have the increment (and general handling) of vIntCount wrong if you want it to check all the elements - this wouldn't work in Java or anything else;
Writing code in broker that uses CARDINALITY and an index like this is hideously inefficient - look up REFERENCE variable and the CREATE statement.
This last is why you need to spend a lot of time reading the documentation and/or getting some proper training. Broker is not a straightforward thing.

You should use reference variables instead of cardinality counts.
A user trace would show how the loop is executing and might show where your counter is not being used correctly.

| what is the point of writing if and else if condition when you are applying same processing mechanism for both. |
