I just wanted to do a follow-up on my earlier post. I worked on this for almost a month mostly because I'm a newb. I searched the forum for answers but couldn't find a way to loop thru a repeating table without code. Hilary provided me a sample which was a big help however I was still stuck. While her sample found and compared items from .xml files, the expression/condition/rule would only see the first item in the repeating table. In short, I wanted to pay it forward and post the two rules I found to work.
contains(xdXDocument:GetDOM("SharePointLibrary")/dfs:myFields/dfs:dataFields/d:SharePointListItem_RW/d:Title[(../d:Month = xdXDocument:get-DOM()/my:myFields/my:Month and ../d:Year = xdXDocument:get-DOM()/my:myFields/my:Year) and (. = current())], .)
boolean(xdXDocument:GetDOM("SharePointLibrary")/dfs:myFields/dfs:dataFields/d:SharePointListItem_RW/d:Title[../d:Month = xdXDocument:get-DOM()/my:myFields/my:Month and ../d:Year = xdXDocument:get-DOM()/my:myFields/my:Year and . = current()])
Hilary, once again, thank you for your help pushing me in the right direction.
Sincerely,
the TOE_CHEESE
