Thanks to Jimmy’s post in http://www.infopathdev.com/forums/p/17807/97253.aspx#97253, I’m able to remove adjacent duplicates from a string created from repeating table with this formula: 

eval(eval(groupName, 'concat(my:fieldName[not(. = preceding::*)], "; ")'), "..")

A sample result looks like this:  Jones, Jerry; ; ; Landry, Tom; ; ; ; ; Johnson, Jimmy; ;

Is it possible to get rid of the duplicate semicolons? 

Thanks SOOO much. 

Yes, you can simply put the predicate with the groupName path rather than the eval path:

  eval(eval(path/to/my:groupName[not(my:fieldName = preceding-sibling::my:groupName/my:fieldName)], 'concat(my:fieldName, "; ")'), "..")

Just what I needed. Thank you SOOO much!  Ya'll are amazing!
