Once you have all the Departments in your PaternMatch multivalue token, then assign the values to a multivalue token using the Remove Duplicates function in the token editor.

Note: you may have to loop through each department value in the PatternMatch tocken to trim them before removing duplicates.

**********************************************************

Sorry, you had stated QF and I gave you Workflow...  In QF, besides you original Pattern Match, add 4 more Pattern Match activities below the first.

In the 2nd Pattern Match, first, apply the Trim function and then apply the Index to return all values separated by the Bar (|) and a pattern of ^\s*(\S.*\S)\s*$ to return all the departments as a single string separated by the Bar.

Note that I am assuming your token from the first Pattern Match that gets all the Department lines is called pmDepartment

In the 3rd Pattern Match, use the Pattern of ([^|]*) to split the single line token back into a multivalue token.

In the 4th Pattern Match, first, apply the Index to return all values separated by the Bar (|) and then apply the Remove Duplicates function and a pattern of (.*) to return all the trimmed departments as a single string separated by the Bar.

In the 5th (final) Pattern Match, use the Pattern of ([^|]*) to split the single line token back into a multivalue token.

Important:  The order of the Function and Index is critical.  You may have to manually arrange them after the functions/index is added.  Note the syntax in the screenshots.

@████████, I appreciate you taking the time to include all these steps.  I haven't tried it yet, but just wanted to be sure we were on the same page.

Are all these steps necessary when looking for the first group of text between Department: and Department: in my line of text above?

Thanks
