I need to find the cardinality of the REQUEST elements

later split the XML into each <MESSAGE/>

Since the message is a large size message can any one give sample for Java compute node.

Please clarify: which cardinality are you looking for: within the message tags or across message tags...

If you are looking for a cardinality across message tags you are SOL with parsing for big messages...

BTW why would you want to use cardinality when you can use references to walk the tree?

I need the total count of <REQUEST> Elements in the whole XML

also it is a large message and I have to split it to each <MESSAGE> and propogate to next queue that too using Java compute node.

Why Java?

This would be very simple in ESQL.

Just setup a reference to the first REQUEST and then loop until there are no more. You can count them as you loop.
