Properties
In the list below required Properties are shown with an asterisk (*). Other properties are considered optional. The table also indicates any default values, and whether a property supports the NiFi Expression Language.
| Display Name | API Name | Default Value | Allowable Values | Description |
|---|---|---|---|---|
| XSLT file name | XSLT file name | Provides the name (including full path) of the XSLT file to apply to the FlowFile XML content.One of the 'XSLT file name' and 'XSLT Lookup' properties must be defined. Supports Expression Language, using FlowFile attributes and Environment variables. | ||
| XSLT Lookup | xslt-controller | Controller Service: StringLookupService Implementations: DistributedMapCacheLookupService ElasticSearchStringLookupService PropertiesFileLookupService SimpleCsvFileLookupService SimpleDatabaseLookupService SimpleKeyValueLookupService SimpleScriptedLookupService XMLFileLookupService | Controller lookup used to store XSLT definitions. One of the 'XSLT file name' and 'XSLT Lookup' properties must be defined. WARNING: note that the lookup controller service should not be used to store large XSLT files. | |
| XSLT Lookup key | xslt-controller-key | Key used to retrieve the XSLT definition from the XSLT lookup controller. This property must be set when using the XSLT controller property. Supports Expression Language, using FlowFile attributes and Environment variables. | ||
| Indent * | indent-output | true |
| Whether or not to indent the output. |
| Secure processing * | secure-processing | true |
| Whether or not to mitigate various XML-related attacks like XXE (XML External Entity) attacks. |
