See also comparing XML files.

I still use the following bash script to compare XML files and usually find its output informative enough, if not more readable than various XML oriented diff tools. 

#!/bin/bash

a=($@)
b=$#
f2=${a[$((--b))]}
f1=${a[$((--b))]}
diff "${a[@]:0:$b}" \
   <(xmllint --c14n "$f1" |xmllint --format -) \
   <(xmllint --c14n "$f2" |xmllint --format -)
