Blake,

The rules are simple: just cut out entire tags (anything goes except the outer <HDDM> tag itself) to kill what you don't want.  I think this is too clear to risk mistakes.  Simply if you kill a tag then all of its contents disappear with it.  It 
sounds to me like you still want to kill the <reaction> ... </reaction> tag and the <mctrajectory> ... </mctrajectory> tag.  After that, you are down to basically just what you want.
