explode an array to hirarchical taxonomy terms and add to imported nodes

how can i import an array that looks like this: Term1 > Term2 > Term3 to xml-file that the texonomy terms are only added to the seperately made nodes?
the addon hiercrchicel taxonomy terms works perfectly but litererally it's writing the terms only into the vocabulary and not also into the nodes.
i did a lot of configurations with the tamper but still i'm not getting through.

does anyone have an idea what to do?
