XPath for mediation flows

The XPath standard is well-suited for creating simple data-driven expressions. Most mediation primitives have properties that are specified with an XPath expression. For example, the root property takes an XPath 1.0 expression that specifies the part of the message that is available to the primitive for processing.

You can also use an XPath 1.0 expression to identify one or more fields in a message and use these fields to filter or select by specifying a value.

You can use the XPath Expression Builder to visually create an expression, or you can write them manually.
