Compare two XML files
Let’s say we have two files:
<!-- first file --> <?xml version="1.0" encoding="UTF-8"?> <sometag attr="1" attr2="2"> Hello </sometag>
<!-- second file --> <?xml version="1.0" encoding="UTF-8"?> <sometag attr2="2" attr="1"> Hello </sometag>
After cleaning with xmllint we can compare them.
xmllint --noblanks --c14n file_one.xml >file_one_tmp.xml;\ xmllint --format -recover file_one_tmp.xml > file_one_canonical.xml xmllint --noblanks --c14n file_two.xml >file_two_tmp.xml;\ xmllint --format -recover file_two_tmp.xml > file_two_canonical.xml diff file_one_canonical.xml file_two_canonical.xml
As you can see, the only difference lays in comments
2c2 < <!-- second file --> --- > <!-- first file -->
XML files were transformed into normal form (http://en.wikipedia.org/wiki/Canonical%5FXML).
