I dont have a reputation, so I cannot add comment to accepted answer by Blender. But his answer will not work in general. Correct version is

//x[.//z]/@name

Explanation is simple - when you use filter like [//z] it will search for 'z' in global context, i.e. it returns true if xml contains at least one node z anywhere in xml. For example, it will select both names from xml below:

  
  
  
     
        Z 
        Z__2
        Z__3   
     
  

Filter [.//z] use context of current node (.) which is xand return only 2nd name.
