OK, then - now we have enough information to provide some guidance.
Start with your previous transaction, and we'll make some modifications.
1. Let's add another transaction input called 'GroupSize", of type integer, and let's give it a value of 2.
2. Let's also add another Local property of type XML, called "Location", and give it an initial value of:
<Location/>
3a. After the sequence/action in which you assigned the individual fields of the Campaign element, add a new sequence with a Conditional action.
3b. Delete the sequence containing the "append xml" link where you were appending individual Campaign items to the CampaignDetails element. We'll replace this with something else in a few moments.
4. Assign an input link to the Input1 property of the Conditional, with the following expression (which will trigger the "true" sequence each "GroupSize" items):
((CampaignRepeater.CurrentItem % Transaction.GroupSize) == 1)
5. Add three child sequences to this conditional (one for the true, one for false, one for "always").
6. Add an an assignment action of type "Append Xml" to the first child sequence below the conditional (the "true" branch) with the following target and expression:
Target: Local.Location{/Location}
Expression: Local.CampaignDetails
This will append an empty CampaignDetails element to the Location element each time a new set of "GroupSize" items are encountered.
7. Add an assignment action of type "Append Xml" to the last child sequence below the conditional (the "always" branch) with the following target and expression:
Target: Local.Location{/Location/CampaignDetails[position() = last()]}
Expression: Local.Campaign{/Campaign}
This assignment will always append the Campaign item to the most recently added CampaignDetails element - this is the effect of position() = last().
You owe me 1000 points now.
