How to use conditional and pattern matching together

Quick Fields

Updated July 2, 2015

asked on June 25, 2015

I have a document class that I'm using pattern matching to pull the date from. The date can appear one of two ways:

Passed and Approved this 6th day of May, 2015

Passed, Adopted and Approved this 6th day of May 2015.

I want QuickFields to run the first pattern match. Then run a conditional process if the first pattern match returned an empty token run the second patter match.

I've got all that setup what I don't know is how to get the tokens combined as one result and what to put in the metadata field?

Any suggestions?

You can do that but you don't really need to. You can make the comma optional in your first pattern by adding a "?" after it to indicate "0 or 1".

Thank you Miruna, how do I make the whole word "adopted" optional?

You can try the following expression:

\w*\,?.*

That would put either value in the token.

Sorry for the late reply. Try this:

Passed(?:, Adopted)? and Approved this (\d\d?)..(\s)day of (.+),(.+)

It returns 6 May 2015 for both examples above.

(?: text) is a non-capturing group construct for pattern matching and the ? after indicates it may or may not be there.
