Modified XML of Variables won't change after importing to Editor

Hi. I have a Group of variable which are made of a structure datatype. I need to edit some of variables properties, to be exact : Limits[1] and Limits[2] text values.
I exported them as XML , and edited via a XML editor. when i import it back, it is not changed at all. What should i do?
