One idea might be to save all values of c in a variable in a format that allows you to differentiate them from one-another, and then every time you encounter c, you check to see if that value is contained within the variable. If it is, skip to the next node. If it isn't, continue processing the current node.

Tell me if you need more specific information

EDIT: As an alternative, and probably an easier method (I've been using NAnt recently, so I might be giving you a NAnt strategy) is to sort all the nodes by their s values. Then just have a variable that stores the current value of c and compare until the value you're looking at isn't equal to the stored value. Then reassign the value and do it again!
