overly-complicated macro text/xml transformation

So I have formed a solution for the problem I was having, but I have a strong feeling that it is probably NOT the best way of going about this. So I have a employee folder at the root of my site content tree, and it has all the employees for the whole company in it. Then under specific state and location pages, there is a reference for that employee in every location where the employee belongs. Locations can have many employees, employees can have many locations. On the original employee page under the employees folder, I want to have a repeater that repeats fields from all of it's linked page's parents. I am able to do this with the following macro:

{%
stringBuilder = "";
for (i = 1; i < CurrentDocument.Links.Count; i++) {
  stringBuilder += "Linked Document's Parent's Name: ";
  stringBuilder += CurrentDocument.Links.GetItem(i).Parent.DocumentName;
  stringBuilder += "<br><br>";
}
return stringBuilder;
%}

Placing this into a transformation and applying that transformation to a repeater on my page gives the desired result:

Linked Document's Parent's Name: ParentPageA

Linked Document's Parent's Name: ParentPageB

Although this works, I can't help but feel that it's extremely error prone, and that there should be a better way. Any suggestions?
