Description:

This processor evaluates one or more XPaths against the content of FlowFiles. The results of those XPaths are assigned to FlowFile attributes or are written to the content of the FlowFile itself, depending on how the user configures the Destination and Return Type properties in the processor. XPaths are entered by adding user-defined properties; the name of each user-added property maps to the attribute name into which the result should be placed. The value of the property must be a valid XPath expression.

Properties:

In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. If a property has a default value, it is indicated. If a property supports the use of the NiFi Expression Language (or simply, "expression language"), that is also indicated.

Modifies Attributes:

This processor adds user-defined attributes if the <Destination> property is set to flowfile-attribute.
