Testing the message content (Filter node)

This topic describes how you can use the Filter node to determine the path taken by a message through the message flow based on its content.

You can customize the Filter node using ESQL statements to determine if the message content meets some condition. The condition tested must yield a Boolean result, that is it must be true or false (or unknown). You can create the test to reference information from a database, if applicable.

You can connect nodes following the Filter node to the corresponding terminals of the Filter node, and process the message according to its content.

Look at the following samples to see how to use the Filter node: You can view samples only when you use the information center that is integrated with the Message Brokers Toolkit.
