I mean apply Expression Language on content : now(), gt, ge
Some more use case details might be helpful to understand what you are trying to do.
While the dynamic properties a user creates in the RouteOnContent processor do support NiFi's Expression Language, the result of that EL is expected to be a Java regular expression which is executed against the content of the FlowFile.
If you want to route a FlowFile using NiFi's EL, you can use the ExtractText processor to extract the relevant part(s) from the content to an FlowFile attribute(s) and then use the RouteOnAttribute processor instead.
Otherwise you will need to create a Java Regular expression to that will accomplish what you want without the use of NiFi's EL functions.
Depending on what your input looks like, you might be able to use QueryRecord as its query supports Expression Language and allows you access to individual fields in the content.
Thanks you!!! In my case need route “CSV” content, example: Id date_col name 1|2018:06:2108:40:00|Ukraine 2|2018:06:2108:15:00|USA If date_col less then 25 minutes of now(), route to rule1 If date_col great equivalent 25 minutes of now(), route to rule2 now() = 2018:06:21 08:50:00 Result 2018:06:2108:40:00 to rule1 <<<<<<<<< 2018:06:21 08:15:00 to rule2 <<<<<<<<<
