using RouteOnAttribute
Hi,
I was trying to use RouteOnAttribute to distribute my data based on the type and configured it as below. But the below configuration didn’t work.
I’d like to understand how the regex needs to be defined in the value field. Is it java pattern matching?

Anup,
Sorry, I'm coming to the party a bit late here, but wanted to point out
a couple of things that may be useful to you.
Corey is correct - the Expression Language Guide should be in the help
menu. This is written very much as a reference guide.
Another NiFi feature that could be very useful for you, though, is the
"auto-complete" feature. When you are editing a property value, after
you type "${", you can press Ctrl + Space. This will give you an
auto-complete feature where you can choose which function you want to
use, and it will also provide you documentation on each function. I.e.,
what the function does, what arguments it expects, return value, etc.
Hope this helps!
-Mark

Good morning Anup,
The expression language guide should be under the help link in the upper right corner of you instance. Or you could right click on a processor, select usage and then scroll to the top of the list. I believe it is the second link, just below the user guide.

Thanks Brandon, That worked. It would be great if you could point me towards the expression language guide.

Anup,
In this case you would want to use the "matches" function as opposed to
"equals". Also, in the email I'm not seeing a closing quote on the value
inside the parentheses. Please let us know if you have any other
questions. Thanks.
All,
I thought we had an expression language guide, but I couldn't find it on
the site... Does anyone have that link, or am I just wrong?

Configuration used:
Routing Strategy: Route to Property name
Added two custom properties:
csv = ${filename:equals(‘.*.csv)}
log = ${filename:equals(‘.*.log)}
