NiFi Expression - Multiple OR - AND Conditions

Explorer

Hi,

I am using RouteONAttribute Processor and i defined a property and its value contains multiple OR and AND conditions like the following:

Property Name: ROUTE1

Property Value:

${text.tag.type:equals('XXX'):and(${txt:contains('YES')}):or(${text.tag.type:equals('YYY')}):and(${txt:contains('NO')})}

The Issue i am facing is that after generating a flow file with attributes text.tag.type = XXX and txt = YES CORRECT it always route to unmatched while it should route to ROUTE1

Thanks ...

Method1:Using UpdateAttribute+RouteOnAttribute Processors

it would be easier if you introduce new update attribute processor before RouteOnAttribute and prepare two new attributes in UpdateAttribute processor.

Configs:

Then in RouteOnAttribute processor use or function to
Configs:

Now processor will route the flowfile to ROUTE1 relationship.

(or)

Method2: By using RouteOnAttribute processor:

Use the below expression in ROUTE1 property value

ROUTE1

${literal(${text.tag.type:equals('XXX'):and(${txt:contains('YES')})}):or(${text.tag.type:equals('YYY'):and(${txt:contains('NO')})})}

Both Methods will result the flowfile into ROUTE1 relationship, Choose the method which best for your case.
