XPath Filter

1. Overview

The XPath Filter service can filter a message using an XPath expression. The XPath expression returns a boolean value. Based on this value and the Inverse value, the message is either let through or sent to the discard flow.

In the table below, you will find an explanation of these properties.

All attributes with a * are mandatory.
