Sayed,

I guess, although you don't say so, you are using child sequences in 
XPointers to locate the elements and attributes of interest to you.

I suggest that you consider (at least going forward) adding an ID attribute 
to relevant elements. If the document structure changes then the value of the 
ID attribute remains the same and provides a stable point for an XPointer to 
use.

I hope that helps a little.
